MultiPASS C530/C560 Chapter 1: General Description

1. FEATURES

1.1 Overview

This product is a G3 transreceiving facsimile based on the ITU-T recommendations. It can be used in telephone networks.

*: This mark indicates a new function.

Picture Quality Color Printer

High quality printing can be accomplished with the Canon Bubble Jet (BJ) method using the maximum

720dpi

×

360dpi resolution. Various kinds of media can be printed with the high speed of a maximum 4.5

pages per minute. The printing paper tray can hold up to 100 sheets of plain paper, 50 sheets of OHP film, or 10 back print films or envelopes.

*Plain paper fax which can transmit/receive in color

Conforming to ITU-T recommendations, this fax is able to transmit/receive in color. Due to containing extremely high-speed 14.4kbps (MultiPASS C530) / 33.6kbps (MultiPASS C560) modems, transmission time can be shortened. Pictures and photographs can both be send and received clearly by UHQ(Ultra

High quality), Canon’s vivid image processing technology. Up to 20 letter- or A4- size sheets, or up to 10 legal-size sheets, can be set in the ADF. 12 one-touch dial entries and 100 speed dial entries can be registered, and group dial and broadcasting transmission can also be done. When paper and ink run out, the data is saved to memory, so there is no worry. When a external-phone is attached, fax communication and normal telephone reception are possible due to DRPD service and FAX/TEL switching.

BJ Cartridge See Page 2-18

Printing quality superior to photos is produced by use of BC-20 and BC-21e/BC-22e BJ cartridges.

*Out-of-Ink Function See Page 2-18

This machine has a function which detects when ink has run out. It also detects when the cartridges of machines equipped with color communications are out of ink. After printing each received page, the ink is ejected in front of a photo sensor in order to detect the presence/absence of remaining ink.

Copy Function

This machine can be used as a 360dpi

×

360 dpi high resolution full color copier. With a monochrome document (including half-tone), up to 99 pages can be copied at one time at the speed of a maximum of 3 pages/minute.

Full Color & 256 Gradation Grayscale Scanner See Page 2-33

Using graphics or OCR software which conforms to the TWAIN standard, full color and 256-gradation grayscale images with a quality of 30dpi ~ 600 dpi can be read into a computer. Reading in can be done at a resolution of 300dpi, and can be enhanced to 600dpi using the included MultiPASS Desktop Manager.

PC Fax

By connecting this machine to a computer, a fax can be transmitted from the included MultiPASS

Desktop Manager or from a Windows application, and a received image can be saved to the computer asis without printing it out.

5.1.1 Electrical shock

Electrical shock hazard

• To prevent electrical shock, be sure to disconnect the power cord and modular jack before disassembly.

• Remove grounding wrist straps before servicing this unit while the FAX’s power is on.

Otherwise, electrical shock may occur.

NOTE

Power supply unit

When power is supplied to this unit, 120 VAC will be supplied to the primary side.

Telephone line

If a telephone line is connected to this unit, 48 VDC will be supplied by this line. When a call signal is received, a voltage of 90 VAC Vrms will be supplied.

5.1.2 High-temperature parts

High-temperature warning

To prevent skin burns, disconnect the power cord and let this unit stand for at least 10 minutes to allow hot parts to cool.

NOTE

NOTE

How to treat burns

Heat of about 122°F or more causes burns. Also, the longer the contact, the more severe the burn.

When treating a burn, the first minute after receiving the burn is the most important.

Cool the burn immediately with cold running water. In case of a serious burn, seek medical attention immediately.

The parts which get hot during operation are indicated. For the location of these parts, refer to the figures.

(Ambient temperature 80°F (27°C) continuous copy operation)

Document feed motor (approx. ~ 104°F (40°C))

Paper feed motor (approx. ~ 118.4°F (48°C))

Carriage motor (approx. ~ 152.6°F (67°C))

Power supply unit (Max. ~ 172.4°F (78°C))

SPCNT board assembly (approx. ~ 176°F (80°C))

BJ cartridge (max. ~ 212°F (100°C))

1-26


5.1.3 Fire hazards

Do not dispose in fire.

Do not dispose of lithium batteries in fire. Doing so may rupture the battery and expose flammable materials.

Follow applicable local regulations when disposing of the SPCNT board assembly’s lithium battery.

Fire hazard

When using IPA or other solvents during servicing, heat or sparks from internal electronic circuits can ignite the solvent. Before using such solvents, be sure to turn off the power source and wait until the high-temperature parts cool. Use the solvent in a well-ventilated area.

5.1.4 Moving parts

Moving parts

To prevent mishaps due to moving or rotating parts during servicing, be sure to disconnect the power cord before disassembly.

Since the this unit does not have a sensor on the printer cover, the carriage and rollers will not stop even if the printer cover is opened during a printing operation. If the printer cover must be opened during printing, beware of the moving parts.

Figure 1-16 shows the driving section’s location.

5.1.5 Preventing ink stains

Avoid touching the BJ cartridge ink nozzles, ink pad, head cap, head wiper, and ink absorbers. The ink can stain your hands, clothes, etc. Although the ink is water soluble, it is permanent and will permanently stain clothing, etc.

NOTE

Although the ink is not toxic, it contains an organic solvent (isopropyl alcohol 67-63-0).

If the ink enters the eyes accidentally, flush the eyes with running water and see a doctor.

If the ink is swallowed accidentally, see a doctor immediately and give the information printed on the BJ cartridge label.

MultiPASS C530/C560 Chapter 1: General Description b) Unpacking the BJ cartridge

Do not open the BJ cartridge packaging unless you are ready to install the new BJ cartridge. Before installing the BJ cartridge, gently remove the orange head cap and the orange protective tape from the nozzles.

NOTE

Storing an opened BJ cartridge

If the BJ cartridge packaging has been opened and the BJ cartridge is not to be installed immediately, store the cartridge in the SB-21 cartridge container, to prevent the printing head from drying out and clogging.

As much as possible, do not open the packaging until the BJ cartridge is to be installed immediately.

5.3 Servicing Cautions

5.3.1 Damage from static charge

This unit contains contact sensors and printed circuit boards equipped with ROM, RAM, custom chips, etc. These electronic components are susceptible to damage caused by static charge.

When disassembling this unit, take care to prevent static charge.

Static electricity

Static charge can damage electronic components or alter their electrical characteristics.

Even plastic tools and hands without grounding wrist straps can generate damaging static charge.

The following items are required to prevent static charge:

• A grounded, conductive mat

• Grounding wrist straps

• A cord with alligator clips to ground this unit’s metal chassis

If you do not have any of the above on hand (during on-site servicing), follow the alternate measures below:

• Use a grounding bag to store and transport printed circuit boards and electronic devices.

• Avoid wearing silk or polyester clothing and leather-soled shoes. Wear cotton clothing and rubbersoled shoes instead.

• Avoid servicing this unit in a carpeted room.

• Before servicing this unit, touch this unit’s grounded terminals to discharge any static charge.

• Wear grounding wrist straps and ground this unit’s metal chassis.

• Always handle the circuit boards and devices along their edges. Do not touch the components and terminals with your fingers.

Shock hazard during power on

If servicing must be performed while this unit is turned on, do not wear any grounding wrist straps. This is to prevent electricity from passing through your body.

5.3.2 Scanner unit a) General Precautions

• Handle contact sensors with care to prevent scratching or smudging of the scanning surface.

Scratches or smudges can cause vertical stripes, etc., to appear on the scanned image.

• Be careful not to scratch the ADF rollers. If the rollers are scratched, paper jams may result.

MultiPASS C530/C560 Chapter 1: General Description a) General precautions

Lubrication points

Do not touch the greased parts of the carriage guide frame, carriage shaft, idler roller and some parts.

Doing so will wipe off the grease which has been applied for the smooth operation of the printer unit.

Do not apply grease to any unspecified parts and surfaces. If grease is on the purge section’s rubber cap or the wiping assembly’s blade, it may cause the BJ cartridge’s nozzles to clog, rendering the BJ cartridge unusable. Also, do not use any grease other than the specified type. Using a different type of grease may dissolve or deform plastic parts.

If you accidentally touch a greased surface, reapply the grease. See the PARTS

CATALOG (provided separately) .

NOTE

Spurs

During servicing, be careful not to damage or deform the spur assembly’s spur tips. If the spur tips are deformed, the area of the paper coming into contact after the printing increases, causing vertical black stripes on the paper.

Carriage ribbon cable assembly

Do not pull or bend the carriage ribbon cable more than is necessary. Doing so may disrupt the cable’s continuity and prevent the printing signals to be sent properly to the cartridge.

Power off during printing

During servicing, do not disconnect the power cord during a printing operation or while the cartridge is being replaced. Otherwise, the cartridge will stop at a position where the ink nozzles cannot be protected by the rubber cap. The ink may then dry and clog the nozzles. During servicing, be sure the cartridge is properly positioned for nozzle capping.

1-49


5.3.4 Paper feed section a) General precautions

Setting the paper size

For fax operations, the user sets the paper size in the PRINTER SETTINGS menu. The unit cannot detect the paper size automatically. Therefore, if the paper size is altered during servicing, be sure to set it back to the user’s paper size setting.

If the paper size setting does not match the size of the paper installed. One of the following two operations will be executed:

(A) If the paper size setting is the same or smaller than the actual size of the paper installed, the following will be executed:

The document will be printed to fit the length of the paper size that has been set.

Even if the paper size setting is smaller than the actual paper size, printing will be executed and no error will result. Depending on the document, large blank areas may result on the printout.

(B) If the paper size setting is larger than the actual paper size, the following will be executed:

As with (A), the document will be printed to fit the length of the paper size that has been set. Since the actual paper size is shorter than the paper size setting, the document's contents would be broken up to fit the paper size setting. “CHECK

PAPER SIZE” will therefore be displayed and printing will be canceled.

5.3.5 Control boards a) Adjustable volume

• The MODEM board’s volume resistor VR1 has been factory-adjusted. Service personnel are not to alter its setting.

• The power supply unit’s adjustable volume VR101 has been factory-adjusted. Service personnel are not to alter its setting.

b) Replacing the SPCNT board

The SPCNT board stores the user data, service data, and other data. Therefore, when replacing the

SPCNT board, print out the stored data and then enter this data into the new SPCNT board.

The memory of the SPCNT Board retains the data on the amount of waste ink the absorbent has drawn and the data used to correct discrepancies in vertical alignment correction. In the light of this, it is important to generate a system dump list before replacing the SPCNT Board.

Using the list, find out how much waste ink the absorbent has drawn; then, after replacing the board with a new one, enter the data, and correct any discrepancies in vertical alignment correction as necessary.

REFERENCE

The SPCNT board replacement precaution is described in “5.4.5 SPCNT board replacement precautions” on Page 1-60 .

MultiPASS C530/C560 Chapter 1: General Description c) Precautions when attaching/detaching the flat cable

Attaching or detaching the flat cable while the machine is turned ON may cause a short in the connector, resulting in malfunction. Always turn the power OFF before attaching/ detaching the flat cable.

5.3.6 Detaching the outer covers

How to open the upper cover

Unless the correct procedure is followed when removing the upper cover, the outer covers may be damaged, and the plastic claws may be broken. Be sure to use the correct tools for the job. If any of the outer covers are damaged during the work, they must be replaced with new ones.

You will have to use a recommended tool or the like when detaching the outer covers (e.g., connector cover, rear cover, upper cover), i.e., to free claws.

To detach the upper cover, you will need to detach other covers first. Particularly, you will not be able to detach the upper cover unless you have detached the connector cover. (For the locations of the claws, see the following diagram.)

• Use a tool whose diameter is less than that of the holes. (hole:3mm

×

1.5mm)

Using lager diameter tools may damage the surface around the holes.

• Be careful not to cause any damage around the holes.

• When detaching the upper cover, take care not to insert the tool more 20 mm in an attempt to free the claw on the left side. Otherwise, you could damage the flat cable inside the machine.

• When detaching the upper cover, be sure to free it from the lower cover by pulling its front toward the front after freeing the claw with the tool. For details, see the Figure 1-23 Opening the Upper Cover .

NOTE

The cover opener (round-tip screwdriver) has been set as a special tool, but any precision screwdriver with a tip diameter of 1.5 mm or less would do instead. If using a substitute, be careful not to scratch any surfaces.

5.4 Data-related Precautions

The memory IC on the circuit board stores the user’s registration data and values for various counters, etc., required for servicing. Although this data is normally retained in memory, it can be deleted by mistake.

When handling this data during servicing, note the following precautions.

EEP ROM

(IC1)

Lithium Battery

SRAM

(IC14)

SPCNT board

Figure 1-25 Memory IC and Backed up Devices

NOTE

PC registration function

Using the MultiPASS Desktop Manager that comes with this product, the user setting items stored in the SRAM can be reprogrammed. The contents of these items are stored as necessary in the settings files in the PC, and at the same time are rewritten into the user setting items in the SRAM, via bi-centronics interface. This function means that, when replacing the lithium battery, or performing repairs that normally entail the loss of data, if the user's PC contains valid settings files, there is no need to reenter user managed data. Refer to the MultiPASS Desktop Manager User's Guide for details of this function. However, please note that service data are not saved.

1-53


5.4.1 Data in the image storage memory (DRAM)

DRAM stores image data which was read other than by a direct transmission. It also acts as a buffer memory to store the image data received. If power is turned off, the memory clear list is printed automatically the next time the power is turned on. The user is thereby notified of the images that were erased from memory.

NOTE

Reception image data

This product is not equipped with image data backup, so that if the power supply is cut, data in memory reception will be lost.

When image data are set to be printed, they will be stored in the DRAM as memory reception images, and “REC'D IN MEMORY” will be displayed. This product does not have a memory reception image transfer capability. If printing is disabled due to a fault in the printing section, check the Memory Clear List, after turning off the power to repair the fault, and request the other party to retransmit the message.

If the setting is for the received image data to be transferred to PC, instead of being printed, the data will be saved as a file in the DRAM, and “RECEIVED IN FILE” will be displayed. To print the contents from the main unit only, press Memory

Reference button then select “FILE PRINT” with the numeric keys. If printing is disabled due to a fault in the printing section, connect to the PC, and start up MultiPASS

Desktop Manager. The file will be exported to the PC, and the contents can be verified on the PC display and saved.

1-54


5.4.2 Data in the control processing memory (SRAM)

SRAM is backed up by a lithium battery. It can retain the stored data for 5 years after the power is turned off. SRAM stores the following data: All the data the user entered with the menu system, the activity reports and other report-generating data, the redial data containing the redial destinations set with the

Redial key, the servicing data set by repair personnel with the service soft switch, and the CS LED lightson duration data. SRAM stores almost all of the data which can be entered or set.

These stored data can be checked with various reports.

NOTE

Jumper Plug Precautions

The data in the SRAM mounted on the SPCNT Board is retained by means of a lithium battery. However, it is important to keep in mind that, for the SPCNT Board supplied as a service part, the jumper plug (JP3) is not shorted so that power is not drawn, thereby preventing unnecessary consumption of power during storage.

When mounting the SPCNT Board, be sure to remove the shorting plug from one of the two shorting pins, and then put it so as to span the two shorting pins.

Further, for the SPCNT Board that comes originally with the machine, a chip jumper

(R90; on the back of the board) is used for shorting instead of a shorting plug; and power is always flowing from the lithium battery of any SPCNT Board that came with the machine. If you want to stop the power for PCB repairs, remove the R90 chip jumper before starting the work; after the work, be sure to solder the chip jumper back in place, and check the voltage of the battery to make sure that it has not been exhausted. If the battery has reached the end of its life, replace it with a new one.

Jumper plug (JP3)

Figure 1-26 Attaching the Jumper Plug

NOTE

Lithium battery life

The lithium battery can last for over 5 years after the power is turned off.

When the power is on, the lithium battery’s power is untapped. Therefore, the actual battery life can be much longer.

When the lithium battery becomes exhausted, “DATA ERROR” will be displayed after the power is turned off or on. When this happens, replace the lithium battery. Since the data in SRAM will be lost when the battery is replaced, it cannot be printed out.

After the lithium battery is replaced and the power is turned on, “DATA ERROR” will be displayed. Press the Set button to discard the contents in SRAM and initialize it to the factory defaults.

Refer to Chapter 3: 3.1 CS LED lights-on Duration Adjustment on Page 3-6 to reset the CS LED lights-on duration.

1-55


5.4.3 Data in the EEPROM

The EEPROM stores the absorption amounts of the waste ink absorber and vertical alignment data. The non-volatile EEPROM does not require any electrical power to retain the data it contains.

Calculation of the total waste ink amount of the waste ink absorber starts immediately after the printer is used. When the absorption amount of the waste ink absorber reaches 100 percent, the waste ink full error is generated and the printing operation is stopped to prevent the waste ink from leaking out.

The vertical alignment data is for correcting any vertical misalignment during bi-directional printing.

The data in the EEPROM can be checked or altered.

REFERENCE

Checking or altering the data in EEPROM

Waste ink absorption amount:

To check the amount, use the service report’s System Dump List. For details, see

Chapter 3: a-2) System dump list on Page 3-63 .

To enter the amount, use the service data #7 PRINTER 3. INK ABS CAPA. For details, see Chapter 3: 5.2.5 New SSSW's/parameters added to this model on

Page 3-39 .

Vertical alignment data:

To adjust the vertical alignment, see Chapter 3: 3.2 Vertical Alignment Correction on Page 3-7 .

Re-entering the waste ink absorber’s ink absorption amount.

The amount data is calculated waste ink absorber. The waste ink absorption amount displayed in the SYSTEM DUMP LIST indicates the percentage of the respective absorber’s maximum capacity that has been reached. The percentage can be indicated and entered in 1% increments. When the waste ink generated immediately after the printer is used reaches 100 percent of the waste ink absorber’s capacity, a waste ink full error is generated for each absorber and the printing operation is stopped. Therefore when replacing the SPCNT board, be sure to check the current absorption amount and enter it in the new SPCNT board.

If the SPCNT board assembly malfunctions and the current waste ink absorption amount cannot be checked, replace the ink absorber and set the waste ink absorption amount to 0%. To replace the ink absorber, see d) Recovery methods for codes indicated as “New” on Page 3-22 .

5.4.4 Replacing ROM

Observe the following precautions when replacing the ROM on the SPCNT board, for example, when replacing a defective ROM or when upgrading the software.

a) Precaution

Print out all battery backed up data.

Reception image data in image memory are erased when power is turned off.

For details on battery backed up data, see Chapter 1: 5.5.1 Data battery backup function on Page 1-62 .

REFERENCE b) Replacement

(1) Make sure that the power cord is disconnected.

(2) Put on the grounding wrist straps to counter electrostatic discharge.

(3) Remove the upper cover, referring to the Parts Catalog (supplied separately) .

(4) Remove the ROM mounted on the SPCNT board using the ROM extractor etc..

(5) Insert the new ROM, making sure that the notches on the ROM package and IC socket are aligned.

When Replacing the ROM

The machine’s SPCNT Board comes in two types: main ROM and printer ROM. If you mounted a main ROM designed for 3.3 V to the socket of a printer ROM designed for 5 V by mistake, you could damage the ROM, requiring extra care during replacement work.

Further, be sure to refer to the following diagram whenever you need to mount a printer

ROM (42-pin IC socket, 40-pin ROM).

Mark

1pin & 42pin not used

MultiPASS C530/C560 Chapter 1: General Description c) Post- replacement precautions

(1) When ROM replacement is performed to replace a faulty ROM, service work is completed after reassembling the fax and turning the power ON.

(2) After ROM replacement is performed to upgrade the ROM version and software switches such as service data and user data settings must be changed, following operations must be performed. This is because the pre-replacement settings stored in the memory have been saved by the battery backup function.

• Perform an ALL CLEAR operation.

After performing ALL CLEAR, reregister the battery backed-up data which you printed out earlier.

5.5.2 BJ cartridge maintenance features a) Cleaning

To maintain high printing quality, the fax unit has a cleaning feature that wipes off dust from the BJ cartridge nozzles with a head wiper and fills the nozzles with fresh ink.

b) Nozzle capping

The fax unit caps the BJ cartridge nozzles with the Capping section cap after the carriage returns to the front of the Capping section on the right side. This protects the nozzles from dust and prevents the ink from drying out or leaking.

c) Maintenance jet

The fax unit has a maintenance jet feature which purges ink from all the ink cartridge nozzles to the purge unit. This prevents the nozzles from clogging and ensures high printing quality.

1-62


5.5.3 Heat protection mechanism

The BJ cartridge head’s aluminum panel becomes hot during printing. It also gets hot if printing continues even after the ink in the cartridge has been depleted. The aluminum panel’s temperature is detected by the BJ cartridge’s head temperature sensor.

• When the carriage is to be moved to the cartridge replacement position, the following applies:

If the detected temperature exceeds 50°C, “WAIT COOLING” is displayed and the carriage does not move. This is to prevent the user from touching the BJ cartridge’s aluminum panel. After several minutes when the temperature decreases, the cartridge replacement procedure must be executed again.

• When a temperature exceeding the standard temperature is detected, the following applies:

During printing, the printing head temperature is monitored every 50 ms. If the printing head temperature exceeds 75°C, a 3.5-second wait period is inserted after each printed line for 20 seconds.

This is to allow the printing head to cool. After 20 seconds, the head temperature is checked. If the temperature has dropped below 75°C, normal printing resumes without any wait period inserted.

However, if the head temperature is still above 75°C, the wait period is inserted after each printed line until the printing head cools sufficiently.

If a head temperature exceeding 100°C is detected for 0.2 sec. during printing, it will be deemed as a BJ head abnormal temperature error and “CHECK PRINTER ##336” will be displayed. The printing operation will also stop.

If a head temperature exceeding 100°C is detected for 1 sec. during printing, it will be deemed as a BJ head temperature sensor error and “CHECK PRINTER ##337” will be displayed. The printing operation will also stop.

5.5.4 Overcurrent protection

The fax unit has an overcurrent protection circuit with a built-in fuse to prevent an abnormal temperature increase if an overcurrent flows to the motors and power supply due to a driver IC problem, software lockup, or short circuiting.

Names and functions of parts

1. Paper Guide

When properly adjusted to the width of the documents, the guide will hold the documents in the horizontal direction to prevent them from skewing when fed.

2. Document Feed Motor

This motor drives all the rollers in the scanner section.

3. Document Sensor (DS)

This sensor uses an actuator to detect the presence of documents to be scanned, and sends that information to the SPCNT board by way of the gate array in the operation panel unit.

4. Document Stopper

This stopper is located to the side of the separation rollers, and prevents documents from entering too far inside the scanning section. This stopper is located here to improve document loading and prevent double feeding or non-feeding due to defective loading of documents.

5. Separation Guide

Separates the documents to prevent double-feeding.

6. Document Feed Lever ➔ See next page.

This lever switches between automatic document feed and manual document feed. Damage to the document caused by the separation roller can be minimized by switching to the manual document feed position when sending single sheets such as thick-stock paper or photographs.

7. Separation Roller

This roller uses differences in the coefficients of friction of the separation guide, document and separation roller to separate each of the sheets in a multiple-page document.

8. Upper Document Feed Roller ➔ See next page.

When the separation roller starts to rotate, the upper document feed roller raises the document stopper so that documents can be fed.

9. Document Edge Sensor (DES)

Using an actuator, the DES detects the edge of a document just before it reaches the contact sensor, and sends this information to the SPCNT board.

10. Document Feed Roller

This roller feeds documents to the color contact sensor after they are separated by the separation roller.

11. White Sheet

This white sheet is used as a whiteness reference when pre-scanning documents.

12. Color contact Sensor ➔ See page 2-32.

The color contact sensor scans the image data from the document, converts it to serial data, and transmits it to the SPCNT board as electrical signals. The color contact sensor has a scanning resolution of true 300 dpi and outputs Red, Green and Blue analog image data.

13. Upper Document Eject Roller

Holds the document between the document eject rollers, and then ejects it.

14. Document Eject Roller

This roller ejects documents fed from the document feed roller.

15. Static Eliminator Brush

Removes static electricity which may have built up on the document in the scanning process, and guards against roller jams.

2-4


NOTE

Initializing the upper document feed roller

When the separation roller starts to rotate, the position of the upper document feed roller is simultaneously initialized to raise the document stopper. Initialization is carried out when the power is turned ON, when documents are inserted and when documents are ejected.

Document feed lever

Switching between automatic document feed and manual document feed is carried out by the document feed lever above the left side of the LCD. During automatic document feed, documents are gripped between the separation guide and the separation roller.

Switching the lever to manual document feed raises the separation guide and frees it from the document. Manual document feed can therefore minimize the possibility of damage caused by pinching between the separation guide and separation roller when feeding documents such as thick-stock paper or photographs. However, because document separation does not occur in manual document feed mode, only one sheet at a time may be loaded. Loading multiple sheets will result in double feed.

Document feed error detection

There are three types of document feed errors which may occur.

a) Feed jam error

When the leading edge of the document is not detected by the document edge sensor

(DES) within 15 seconds after the start of document feed, a feed jam error is detected and document feed is terminated.

b) Document extraction error

When a document is extracted after document feed has started but before the DES is turned on, a document extraction error is detected, and feeding is terminated.

c) Eject jam/document too long error

When the trailing edge of the document is not detected within one meter of feeding after the document’s leading edge is detected, an eject jam/ document too long error is detected and feeding is terminated.

When one of these types of jams occurs, all data which have been read and stored in memory (which are not part of a page that has already been completely transmitted or copied) are erased.

Names and functions of parts:

1. Paper guide

The paper guide which slide manually is fixed align with the left side of the paper, to prevent skew.

2. Lifting Plate

This plate moves upwards by the force of the springs and the release cam mechanism, lifting the paper stack until it touches the Pickup Roller. After separation, it moves back down to its original position.

3. Pickup roller ➔ See Page 2-8.

The pickup roller has a semi circular roller. This roller is rotated once, and sends the paper once sheet at a time, as a result of corresponding operation with the lifting plate.

4. Pickup Roller Sensor (PRS)

This sensor monitors the initial position of the Pickup Roller position.

5. Paper Separator ➔ See Page 2-9.

The paper separator catches the corner of the recording paper or envelope, and holds the extra paper back.

6. Paper Edge Sensor (PES)

This sensor monitors the paper feed state, and detects jams and misfeeds.

7. Paper Feed Roller ➔ See Page 2-8.

The Paper Feed Roller transports paper, which has been picked up by the automatic sheet feeder, to the printing position in the Printer Section. It then feeds the paper one line at a time, in coordination with the carriage movement.

8. Paper Feed Motor ➔ See Page 2-8.

The Paper Feed Motor drive the paper supply mechanism and purge unit.

9. Transmission Roller

The transmission roller transmits the driving force of the paper feed roller to the paper eject roller.

10. Paper Eject Roller

A roller used to eject the paper.

11. Spur

This spur is used to transport the printed paper properly, without damaging its printed surface. It is shaped so as to make it difficult for ink to stick to it.

12. Cleaner Roller

NOTE

Paper feed motor drive switching

Power from the paper feed motor is switched for separation and feed of the paper, and nozzle cleaning mechanisms by the direction of paper feed motor rotation, the slide lock pin on the purge unit and swing gear. When the carriage moves in front of the purge unit, the carriage pushes the control pin, and releases the swing gear driven by the paper feed motor. When the paper feed motor rotates in the paper feed direction in this state, the swing gear rotates and moves up to the auto sheet feeder drive gear to drive the auto sheet feeder. Alternately, when the paper feed motor rotates in the reverse direction, the swing gear rotates and moves up to the purge drive gear to drive the purge unit.

When the control pin is locked, the paper feed roller is driven to feed the paper.

NOTE

Paper Separation Mechanism (Automatic feed)

This model has no paper selection lever on the automatic sheet feeder.

If the paper meets specifications, it can be fed without selecting operation the paper type.

The paper is loaded in the auto sheet feeder such that a corner of it is caught by the paper separator. When printing starts, the pick-up roller starts to rotate through the drive of the paper feed motor. Plain paper is fed with its corner held by the paper separator, and then pushed into the paper feed section. When printing on thick paper like envelopes, as the paper is stiffer than the return force of the paper separator’s spring, the paper separator is pressed down to feed the paper.

Initial position of the pick-up roller is detected when the flag is sensed by the pick-up roller sensor on the SPCNT board.

When the paper is sensed by the paper edge sensor for over a second, it is fed automatically until it reaches the starting position for printing.

If the paper is not sensed even when the paper pick-up operation is executed, it is executed again. If the paper is still not sensed, it is assessed as a paper feed error.

NOTE

Paper feed error detection

There are three types of paper feed error which may occur: a) No paper error

Occurs when the Paper Edge Sensor does not detect the paper’s leading edge the start of the paper picked up operation is executed, it is executed again. If the paper is still not sensed , it is assessed as a No paper error.

b) Eject delay jam

Occurs when the Paper Edge Sensor does not detect the paper’s trailing edge after the page has been printed, or after 22 inches (558.8 mm) of paper eject operation has been performed.

c) Paper size error

When the size of the paper being fed is different from that registered in the user data, and the page being printed is divided during printing, a paper size error will occur.

When a paper feed error occurs, memory reception begins from the page at which the paper feed error occurred.

When copying, the data are erased from memory as soon as an error occurs.

Names and functions of parts

1. Home Position Sensor (HPS) ➔ See Page 2-13.

This sensor detects the home position edge and carriage position. Also, at the capping position, the on/ off of purge sensor flag during the pump operation is detected.

2. Carriage Motor

This is a stepping/pulse type motor, which is controlled with pulse width modulation. It moves the carriage by belt drive.

3. BJ Cartridge ➔ See Page 2-18.

4. Carriage

Driven by the carriage motor, the carriage moves horizontally across the paper. Through the carriage ribbon cable, the printing signals from the logic board are transmitted to the BJ cartridge in the carriage.

By controlling the purge unit’s slide lock pin, the carriage controls the engagement of the paper feed motor’s drive power between the paper feed/purge unit and the sheet feeder.

5. Paper thickness adjustment lever

Adjust the gap between the print head and paper according to the thickness of the paper.

6. Purge unit ➔ See Page 2-13.

In order to maintain the BJ cartridge’s high print quality, the BJ cartridge’s nozzles and spray orifices are cleaned by a wiper and pump. When in standby mode, the BJ cartridge’s spray orifice section is covered by a rubber cap to prevent the nozzles from drying out and ink from leaking.

The purge unit controls the swing gear. This gear switches power from the paper feed motor for separation of the paper, paper feed and nozzle cleaning.

7. Ink Detection Sensor ➔ See Page 2-16.

Ink is ejected directly over the optical axis of a pass-type photosensor, which detects the change in light intensity to determine whether or not ink is being ejected.

8. Waste ink absorbers

Absorb waste ink from cleaning or ink empty detection.

NOTE

BJ head protection

In order to always maintain good print quality, this model performs cleaning of the BJ head at appropriate times.

There are three types of cleaning operations: pump suction, wiping, and maintenance jet. Also, the print head is capped after printing, to preserve the head.

• Cleaning operation (pump suction)

Cleaning operation is performed using the cap and pump of the purge unit.

The cleaning operation is performed at the following times:

• When the user initiates a cleaning operation

• At power-on

• When the BJ cartridge is changed

• At the start of a print operation when at least 72 hours has passed since the last cleaning

(However, when using the BC-21e/BC-22e, the first cleaning after changing the BJ cartridge/ink cartridge will occur when a print operation begins after 24 hours or more.)

• Wiping operation

When the carriage passes by from left to right, the wiper blade drops down so that it does not touch the print head. When the carriage passes by from right to left, the blade rises to contact the print head and wipe away paper fibers and ink residue.

The wiping operation is performed at the following times:

• At the start of printing when less than 72 hours has passed since the last cleaning operation

• Every 60 seconds during printing (or after a fixed number of dots have been ejected)

• During a capping operation

• Maintenance jet

The maintenance jet operation prepares the nozzle spray orifice ink surface shape by performing an ink test, firing at the maintenance jet absorber.

The maintenance jet operation is performed during a cleaning operation, after a wiping operation, and after a fixed time (BC-20: 12 seconds; BC-21e/BC-22e: variable, between 5 and 20 seconds) while printing.

• Capping after print completion

The capping operation is performed at the following times:

• When a fixed amount of time passes after the completion of printing without new print data being received by the Printer Section

• During printing, after the second wiping operation (i.e. after 120 seconds) with no print data received by the Printer Section

• After changing the BJ cartridge

2-14


NOTE

Print Shift Correction

Print gaps can occur when doing bidirectional printing, due to changes in the weight of the BJ cartridge and mechanical errors. This gap is corrected by adjusting the carriage drive motor load and the carriage position, which is determined logically from the number of stepping pulses. Gap detection is performed before the start of printing, during the home position detection operation.

2-15


NOTE

Ink empty detection

Ink empty detection during fax operation is performed by firing ink between the light source and receptor of the ink sensor, located on the left side of the printer. This function does not work with the BC-22e, only with BC-21e or BC-20.

When ink passes between the source and the receptor, as shown in Figure 2-10 , the sensor output will be a pulse waveform. The presence of ink may be determined from the pulse generation time.

Ink empty detection is performed at the end of each received page of printing. If ink is not detected on the first detection attempt, the ink nozzle is shifted slightly, and the detection operation is repeated to double-check the first detection operation. If it is determined that there is ink remaining, the image data for that page will be erased from memory. If the cartridge is out of ink, the message “REPLACE CARTRIDGE” (with

BC-20) “BLACK INK EMPTY”/“COLOR INK EMPTY” (with BC-21) will be displayed to inform the user that the cartridge is out of ink, and the page will be

“received” to memory again from the image data.

Method of Remaining Color Ink Detection

The method for detection of remaining color ink is the same as that for the detection of remaining black ink. Sensor output is changed by passing each color (Cyan, Magenta,

Yellow) in front of the ink sensor after the received image is printed. By counting the time of this change, the presence or absence of ink is detected. The sensor output also changes according to color, so the threshold value of the sensor is adjusted so that it can be reliably detected as normal. If one of the CMY colors is detected to be absent,

"COLOR INK EMPTY" displays, informing the user that there is no more ink. When color ink has run out, the image is not printed as a BW image, no matter whether there is black ink available or not.

The timing of the check for remaining volume of color ink is only either after the cartridge replacement button is pressed, or when a received image is automatically output. Also, when the BC-22e cartridge is being used, the check for remaining volume of color ink is not performed when copying is done, when PC printing is done, or in corresponding circumstances.

The detection level of the ink detection sensor is adjusted automatically by means of a feedback circuit, and thus requires no manual adjustment. If the sensor output does not reach a standard level, even after performing feedback control (such as if the receptor is completely blocked, or if a sensor defect occurs), the ink sensor failure will be reported with the display of the “CHECK PRINTER” (error code ##348) message.

NOTE

Waste Ink Absorbers

This model has a single ink absorber which absorbs waste ink as follows.

• Suction waste ink

Waste ink sucked from the cap

• Maintenance jet waste ink

Waste ink from the test firing used to adjust the nozzle condition

• Ink detection waste ink

Waste ink fired to detect the presence of remaining ink during fax receipt

The amount of ink absorbed is counted as a total of all of these. When the counted absorption levels reach 100%, the “CHECK PRINTER” message (error code ##342) will be displayed, and printing will stop to allow the absorber to be changed. To clear the error, it is necessary to replace the absorbers and to reset the waste ink absorption level counts. The waste ink absorber should be replaced after this. For the method of resetting the waste ink absorption level counts, see Page 1-56.

5. BJ CARTRIDGE

This model accepts three types of BJ cartridges, the BC-20, BC-21e and BC-22e.

5.1 Structure a) BC-20 Black BJ cartridge structure

The black BJ cartridge contains a 360 dpi

×

128 nozzle bubble jet print head unit, on-demand thermal ink jet type, containing 44 ml of ink. The black ink contained in the ink sponge is filtered with a meshed ink filter to remove dust, and sucked into bubble jet print head unit through a joint pipe.

b) BC-21e Color BJ cartridge structure

The color BJ cartridge has a printing head equipped with 360 dpi/720 dpi

×

136 nozzles through which the four ink colors are ejected (24 nozzles each for yellow, magenta, and cyan; 64 nozzles for black). The ink cartridge (one for black and one for the other three colors) are removable and replaceable. The BCI-

20 black ink tank contains 9 ml of black ink. The BCI-21 color ink tank contains 5 ml each of yellow, cyan, and magenta ink.

When drop modulation technology is used, small dots are printed in low density areas to minimize the graininess and large dots are used for high density areas. Using this technology allows the printer to retain its printing speed and achieve high quality printing.

c) BC-22e Photo Color BJ cartridge structure

The photo color BJ cartridge has a printing head equipped with 360 dpi

×

136 nozzles through which the four ink colors are ejected (24 nozzles each for yellow, magenta, and cyan; 64 nozzles for black). The BJ cartridge contains 9 ml of black ink , 5 ml each of yellow, cyan and magenta ink. Adopting drop modulation technology, the photo BJ cartridge prints small dots in low density areas to minimize the graininess and large dots in high density areas to retain its printing speed and achieve high quality printing.

5.2 BJ Head Driver Block Diagram

• 128/136 bit shift resistor

Stores the printing data (HDATA) transferred from the control board at HCLOCK’s timing.

• 128/136 bit latch

Latches the printing data (HDATA) converted by the 128/136 bit shift resistor.

• Block enable decoder

After the BENB (Block enable) 1, 2, and 3 code signals are input, the specified heat timing signal is output. The heat timing signal is divided into eighth.

• Heater (1 to 128 and 1 to 136)

The heater generates the bubbles required for the nozzles to eject the ink. The heater heats the bubble jet nozzles. Heating is executed with the timing signal produced by the block enable decoder and the even nozzle heat enable (EvenENB), odd nozzle heat enable (OddENB), and heat enable (HENB0 to 3) signals.

• Sub heater

This heater maintains the optimum conditions in the nozzle for ejecting ink.

• Temperature control heater

This heater controls the head temperature to stabilize the ink ejecting amount.

• Rank resistor

To execute optimum heat control of each BJ cartridge, production-related deviation in heater characteristics is classified into 13 types which are identified by changing the rank resistance. From the printer MPU’s analog port, the printer MPU detects the different rank resistance as voltage values and converts them from analog to digital for detection. The heater’s characteristics are thereby recognized.

• Head temperature sensor

Temperature changes in the nozzle’s heater are detected by the diode to prevent the bubble jet head from overheating.

• Cartridge ID

With the ID0, ID1 and INKS2 combinations, the BJ cartridge type (color or black or photo or Multi Drop) is recognized.

5.3 Printing Signal a) Black BJ cartridge drive control

The black BJ cartridge driving control is executed by dividing the head’s 128 nozzles into 8 blocks (16 nozzles each). These blocks are further divided into odd and even blocks (8 nozzles each). The odd blocks eject ink simultaneously, and the even blocks do so as well. The control signals for the former are the block enable 1, 2, and 3 signals (BENB 1, 2, 3), and for the latter the signals are the even/odd enable signals (Even/odd ENB).

The heat enable 0 and 1 (HENB 0, 1), which are the heater drive control signals for ejecting the ink, comprise the pre-pulse and main pulse. To constantly achieve optimum ink ejecting, the internal conditions such as the head’s rank, printer temperature, head temperature are monitored, and the heater drive pulse width is varied before the pulse is output. Also, the printing drive signal from the printer controller is transferred to the BJ head’s shift resistor according to the HLATCH timing.

The printing drive signal (HDATA) is latched and when the printing control signal and heater drive control signal are output together, the heater for the applicable nozzles is driven, and the ink is ejected.

b) Color BJ cartridge drive control

The color BJ cartridge head’s nozzle configuration differs from that of the black BJ cartridge. (The black has 64 nozzles while the color has 24 nozzles each for Y, M, and C.) Therefore, the number of nozzles in each control block is different from that of the black BJ cartridge. Also, since the heaters are driven simultaneously for each color, the heater drive control signals used are the heat enable (HENB) 0, 1, 2, and 3 signals. Otherwise, everything else is the same as with the black BJ cartridge.

For heat enable, the HENB 0, 1, and 2 signals drive the nozzle heaters for Y, M, and C. The HENB 3 signal drives the nozzle heater for black ink.

H ENB 3 c) Color BJ Cartridge (Multi Drop) Drive Control

The multi drop type color BJ cartridge’s printhead has 136 nozzles and each nozzle has two heaters located one infront of the other. The printing operation using this multi drop type color BJ cartridge is

(dependent/influenced) by how these heaters are controlled.

The sequence of ink ejection is as follows. The 136 nozzles has 8 function blocks (16 nozzles/block) and each block is separated into two functional units. Hence, each functional unit has 8 nozzles. Ink is consecutively ejected from each unit.

Selection of the nozzles to be ejected is done by BLOCK ENABLE signals 1, 2 and 3 (BENB 1, 2, 3) and the EVEN/ODD ENABLE signal (Even/Odd ENB). HEAT ENABLE (HENB 0, 1, 2, 3) is the heat drive control signal for ejecting ink.

The HEAT ENABLE signal controls ink ejection as follows:

HENB 0: signals the nozzle (black) at the back

HENB 1: signals the nozzle (black) at the front

HENB 2: signals the nozzle (color) at the front

HENB 3: signals the nozzle (color) at the back

The HEAT ENABLE signal is made of up the prepulse and the main pulse. To optimize ink ejection, the head rank, printer’s inner temperature and head temperature is constantly monitored. The ink is ejected by varying the HEAT ENABLE pulse width.

8. NEW FUNCTION

8.1 High-speed Transmission

The image transmission time is reduced drastically compared with the previous models by the V.34 modem

(maximum transmission speed 33600 bps) recommended by ITU-T.

8.1.1 V.8/V.34 protocol a) Outline

• The V.8 protocol is used as the startup protocol to move to V.34. The V.8 protocol enables connection with fax machines, data modem and equipment using existing V-series modems. The

V.34 modem contains a modem circuit based on the previous recommendation to connect with the previous modems and has upper compatibility.

• The actual data transmission speed is improved entirely on average by speeding the modulation method and utilizing new techniques, such as the pre-emphasis technique *1 for increasing the S/N

(signal-to-noise) ratio and the probing technique *2 for measuring line characteristics and optimizing the modem operation according to the line condition.

• The V.8 protocol, V.34 pre-protocol and post-protocol use full-duplex transmission to speed the processing.

• Fourteen image transmission speeds *3 are available:

33600, 31200, 28800, 26400, 24000, 21600, 19200, 16800, 14400, 12000, 9600, 7200, 4800, and

2400 bps

• The modulation speed (baud rate) *4 can be selected from among 2400, 3000, and 3200 symbols/sec

(required) or 2743, 2800, and 3429 symbols/sec (option). The data transmission speed can be set more finely than the previous modems.

NOTE

*1 The output level of a high-frequency zone with comparatively high noise is raised, and then the transmission signal is sent.

*2 A tone signal known as a probing signal (L1 and L2) is output, and the receiving side measures the characteristics of the line.

*3 The data signaling rate is recorded in the ITU-T standards manual. Image transmission speed means the same as data signaling rate.

*4 The symbol rate is recorded in the ITU-T standards manual. Symbol rate means the same as moderation speed and baud rate.

2743 symbol/sec cannot be used with this fax.

2-36


NOTE

1. The V.34 protocol uses ECM. If the ECM SW in user data is set to OFF, the V.8

protocol is not executed. Therefore, the V.34 protocol is not used, and V.17 or a lower protocol is selected.

2. If the transmission speed is set to 14400 bps or lower, the V.8 protocol is not executed and V.17 or a lower protocol is selected.

3. After the V.21 protocol is selected first, it can be changed to V.8 or V.34. (See c-1) )

4. When the V.34 protocol begins, it falls back within the V.34 protocol, but it does not fall back to the V.17 mode or lower.

8.2 JBIG Image Compression Encoding Method

8.2.1 Outline of the JBIG image compression encoding method

The JBIG Image Compression Encoding Method is recommended in ITU-T T.82/T.85 as a new bi-level

(bi-level: White and Black) image compression encoding method developed by JBIG (Joint Bi-level

Image experts Group).

The JBIG Image Compression Encoding Method has the following characteristics with regards to text documents, quasi-gray scale images with little continuous black and white, and gray scale images which use a dithering method: a higher compression rate (1.1 ~ 30 times higher) than the conventional MMR compression method, the encoded volume will not exceed the volume of original image information after compression, and when decoding, the image can be completely re-assembled to its original condition in the same way as with conventional MR/MMR.

The JBIG Image Compression Encoding Method contains Progressive Bi-level Image Compression for searching image databases, recommended in ITU-T T.82, and Single Progression Sequential Bi-level

Image Compression for facsimile, recommended in ITU-T T.82 and T.85.

Images will take on the form shown below.

Sequential

Figure 2-31 Images

2-50


NOTE

The characteristics of Progressive Bi-level Image Compression are explained below as a reference. First of all, after the original image has been read in at high resolution, it is converted to low resolution, and this low resolution image data proceeds to be encoded

(compressed). On the receiving end, the overall original image can be quickly recognized by the steps in which this low resolution image compression data is received.

Next, to improve the quality of the low resolution image already sent, only information needed to improve the resolution is forwarded. The previous low resolution image is decoded on the receiving side with this information, and following this, the high resolution image is displayed on top of the previous low resolution image.

It is easy to quickly recognize the original image in the process of displaying the image from low resolution to high resolution in order by using this method, with a CRT display for example. Also, according to the situation, it is possible to interrupt the image transfer at the point where the original image is recognized to some degree by the receiving side.

This method requires a page buffer memory for the low resolution image because the low resolution images are used for the purpose of high resolution image encoding.

8.2.2 Single progression sequential bi-level image compression method

The Single Progression Sequential Bi-level Image Compression Method used in this fax is explained below.

The Progressive Bi-level Image Compression Method uses multiple resolution layers on a single page

(multi-level layers, low resolution layers~high resolution layers) to perform encoding/decoding. In the

Single Progression Sequential Bi-level Image Compression Method, encoding is done in units of horizontal bands (a number of lines) called stripes, and is performed from left to right, top to bottom (this condition is called sequential), and in one resolution layer (single layer).

In this method, the encoding is done in stripe units, so it is completed with a buffer memory much smaller than a page buffer memory.

NOTE

The methods by which encoding takes place and by which image data is constructed after encoding are explained below.

2-51


8.2.3 Encoding method

In the JBIG encoding used in the Single Progression Sequential Bi-level Image Compression Method, uses in the encoder shown below to encode to the original the results of comparison of the line currently being processed and the previous line, as well as the predicted value of an image pixel (white or black) used in a model template.

The study table used in the prediction makes the next prediction more accurate by learning and correcting the study table every time the model template moves to the adjoining pixel. It is characteristic of this method that if the prediction is accurate the amount of encoding will not increase, and if the prediction is off the amount of encoding increases, so the increase in prediction accuracy of this study table is very important.

An outline of the encoding procedure is shown below.

Output of image data encoded by JBIG

Figure 2-32 Encoder and Flow of JBIG Encoding a) In the pattern prediction section, the line currently being processed and the current line are compared, and judged to match or not match. A flag showing whether or not the lines match (1 bit, 0: match, 1: don't match) is attached to the head of each line according to this judgment. When the lines match, only this flag is encoded in the arithmetic encoding section as a suspected pixel, the pixel of the line being currently processed is not encoded. When the lines do not match, the pixel of the line currently being processed is encoded in the arithmetic encoding section based on the results of a comparison of the value of the actual pixel and the pixel (white or black) which is predicted using the model template and the study table.

NOTE

When the lines are judged to match, the line currently being processed is said to be

"typical". When the lines are judged to not match, the line is said to be "not typical".

When the very first line of an image is predicted, the background color is used as the previous line.

MultiPASS C530/C560 Chapter 2: Technical Reference b) In the model template, the combination (10-bit pixel pattern) of 10 pixels is output to the arithmetic encoding section using the template shown below (inside the bold outline).

All of the 10-bit pixel patterns inside this template exist in the study table. This 10-bit pixel pattern is used by the arithmetic encoding section to refer to the predicted value of the pixel and the status number in the study table which correspond to the 10-bit pixel pattern.

NOTE

There are two types of model templates ~ 3-line and 2-line, and the one selected is designated by the LRLTWO inside the Bi-level Image Header section (BIH). The pixel shown by "X" is an encoded pixel and is outside of the template.

The pixel shown by "AT" is a special pixel known as an AT pixel. The AT pixel becomes a Adaptive Template by having its position moved, and is very effective when encoding a periodic pixel, similar to a dither pattern image.

The position of AT in the figure is the beginning position of the AT pixel.

In this fax, it remains fixed in this initial position, so Adaptive Template is not used.

c) The study table, as shown below, is constructed by all of the 10-bit pixel patterns output by the model template, and their corresponding status numbers and predicted values of the pixel to be encoded.

The predicted value of the pixel to be encoded and the status number is compared to the actual pixel in the arithmetic encoding section every time the model template is moved to the adjoining pixel.

The result of this comparison (matches / does not match predicted value) and the status number are then checked by comparison to the probability estimation table, and the study table is corrected

(learned) to a new prediction value and status number which will be used when the same pixel pattern is found again.

By learning in this way, the probability of the study table matching the next time is increased, and the need for encoding decreased.

Example:

A brief explanation of how the study table works is given below.

It is assumed that each of the model template pixels 1~10 in the image below are white.

1. In this case, the model template pixel pattern is 000h.

2. The predicted value of pixel pattern 000h for pixel "X" is "white," but it is actually black. Thus the prediction is "inaccurate."

3. The status ST is "0", so the probability estimation table is consulted, and the next status is moved to

"1." At the same time, by the reversal of the predicted value, the next prediction is for "black."

4. Next, the model template is moved to the adjoining pixel in order to perform the next prediction. At this time, pixels 1~9 of the model template are white, and pixel 10 is black.

5. In this case, the model template pixel pattern is 001h.

6. The predicted value of pixel pattern 001h for pixel "X" is "white," and it is actually white. Thus the prediction is "accurate."

7. The status ST is "0", so the probability estimation table is consulted, and the next status is moved to

Figure 2-36 Study Table Study Example 2

The study table is constantly updated in this way, increasing the probability of accurate predictions.

2-55

MultiPASS C530/C560 Chapter 2: Technical Reference d) The probability estimation table, published in the ITU-T T.82. Its contents are fixed, differing from those of the study table.

NOTE

This table shows probability of accuracy/inaccuracy in the form of a range, according to the accurate/inaccurate results of a given status prediction value.

The plan of the probability estimation table is such that if the prediction is accurate, the range of the next status number will be smaller than would be the case in an inaccurate prediction.

The status number with this smaller range will be selected to be the next status number.

e) After the predicted value is found to be accurate/inaccurate by the actual pixel, the model template, and the study table, that accuracy/inaccuracy is encoded in the arithmetic encoding section, and the encoded image data is output.

f) In the encoding (mathematical encoding) done in the arithmetic encoding section, there is no conversion table for encoding as is the case in encoding with conventional MH and MR. Using the

LSZ (probability estimation value of an inaccurate prediction: the form of a range) of the probability estimation table and the accuracy/inaccuracy of the predicted value as a base, encoding is done by showing the position of the progress of the prediction on an integer line (between 0~1.0). Encoding shown as a position on this integer line, take a position under MPS in the case of accurate predictions, and under LPS in the case of inaccurate predictions, as shown in the figure below.

Furthermore, there is a concept of range (A) in this arithmetic encoding. This range (A) *2 is shown as an MPS range in the case of accurate predictions and as an LPS range in the case of inaccurate predictions for each pixel. When these ranges (A) are below a certain range *3 , the leading edge bit

(which excludes the encoding "0". shown by the position on the integer line) shifts one position to the left as encoded image data, and is output. At this time, the limit of this range (A) which was below the certain range is narrow and it is difficult to show a position more detailed than this, so the range (A) is magnified *4 to show it in more detail. This operation is called "Renormalization", and this range (A) is reset to a value above a certain range *3 .

2-56


The concept of alithmetic encoding is simply explained below.

The following assumptions are made in order to make the explanation easy to understand.

The probability of accuracy will be 50%, and the probability of inaccuracy will be 50%.

Figure 2-37 Arithmetic Encoding Conceptual Diagram

The special characteristic of this arithmetic encoding is that an additional encoding bit is not needed because the integer line position is the same as the integer line position of the previous encoding data in the case of an accurate prediction. It follows that the amount of encoding will not increase if accurate predictions continue, and the rate of compression will increase. Conversely, with inaccurate predictions, an additional encoding bit will be necessary to show the position of the inaccuracy in detail, and thus the amount of encoding will increase and the rate of compression decrease. In this way, the study table learns in order to increase the rate of accurate predictions and to reduce the amount of encoding and raise the compression rate during the encoding process, and then corrects the table parameters.

NOTE

*1 The actual probability varies with the status because of the extent to which LSZ occupies in the range (A).

*2 The actual range is hexadecimal 8000~10000.

In the case of an accurate prediction, range A1= hexadecimal 10000-LSZ, A2=A1-

LSZ, and A3=A2-LSZ.

In the case of an inaccurate prediction, range A=LSZ.

*3 Actually, hexadecimal 8000.

*4 Actually, the hexadecimal value will be shifted to the left two times, and the hexadecimal will be over 8000.

2-57


Next, the encoding for continuos accurate predictions will be simply explained.

The assumptions below will be made for easy understanding.

The value of an accurate LSZ will be decimal 100 *1 in all statuses.

Range A will have limits of decimal 8000~10000 *2 , and when range A is below decimal 8000 *3 , the lead encoding bit will be pushed out, and the encoded image data will be output.

At this time, Range A will be adjusted so that it is over decimal 8000 *3 (decimal 1000 *4 added).

An accurate range will be MPS, and an inaccurate range will be LPS.

8.3.2 Reading color documents

When scanning a line of a color document, the LED’s are sequentially lit: first Red, then Green, then

Blue. The corresponding image data of the line are then read and stored to memory. The Red, Green and

Blue LED’s are mounted on the white LED board at the right side of the contact sensor. The light emitted from the LED’s passes through the optical guide, where it is reflected, gathered, and projected at the document.

During color copying, the SPCNT board’s system control IC (IC 4) uses the 8-bit data stored in memory for each LED color to generate print image data for the colors Cyan, Magenta, Yellow, and Black

(CMYK data). Generation of CMYK data is independent from the reading contact sensor data. When

CMYK data generation is slower than the reading process, reading is halted until CMYK data generation is completed.

When using the unit as a color scanner, the Red, Green and Blue data which were scanned and stored to memory are converted to parallel data and sent to the PC via the Centronics interface.

8.3.3 Reading black & white documents

When scanning black and white documents, the Red, Green and Blue LED’s are lit sequentially for 1/3 the duration used for color scanning, providing illumination equivalent to the same duration of white light.

b) Interface Functions

This machine supports 3 bi-directional Centronics modes - compatible mode, nibble mode, and ECP mode. These are included in IEEE-P1284 D2.00, which was published on September 10, 1993. Where the host computer supports ECP mode, this machine will transfer data in ECP mode. When the host computer does not support ECP mode, this machine will transfer data in compatible mode and nibble mode. Some host computers must have ECP mode set.

Compatible Mode

This mode conforms to conventional Centronics interfaces. The host computer transfers 8 bit-data (in sequential direction) a peripheral machine in 8 data lines.

Nibble Mode

A peripheral machine transfers data to the host computer with this mode. The 8-bit data is divided into 2

4-bit units, and transfers the 4-bit data to the host computer 1 unit at a time by 4 control lines.

Bi-directional transfer can be accomplished by simultaneously using both of the methods mentioned above - compatible mode (sequential direction transfer), and nibble mode (reverse direction transfer).

ECP Mode

ECP stands for Extended Compatibility Port. High-speed data transfer can be accomplished with ECP mode. Data can be transferred faster than in nibble mode because data lines can be used in both directions without changing modes. Optionally, transfer of compressed data can also be done.

8.5 Color Communications

A scanner capable of color scanning and a printer capable of color printing are combined, and a color document is transmitted/received. Communication procedures are basically the same as conventional ECM communications procedures, but the JPEG compression encoding method used in the compression of color images is adopted as the compression method. This machine is capable of full color image transmission/ reception through conformation to the ITU-T standard. Because it conforms to the ITU-T standard, it can communicate with other manufacturer's machines.

NOTE

CIELAB color spacing

In the JPEG compression used in G3FAX, it is necessary to compress/decompress images with color spacing called L*, a*, b*. CIELAB is defined color spacing by CIE

(Commision Internationale de l'Eclairage). It is the space which holds the optically near-equivalent and distinguishable difference in the interval between points of equal space. Here, L* shows the brightness (luminosity index), and a* and b* show the variation in color (a* shows tones from green to red, b* shows tones from blue to yellow.)

L*,a*,b* are the color ranges expressed by real numbers determined as shown below:

L*=[0, 100] a*=[-85, 85] b*=[-75, 125]

It is inconvenient to digitally process this as-is, so the colors are handled by rounding off the values to the closest integer. The method used to calculate expressions for 8bit pixels is as below.

L=(L*)*(255/100) a=(a*)*(255/170)+128 b=(b*)*(255/200)+96

Sub-sampling

The smallest unit processed by JPEG is called the MCU (minimum coded unit). This is an image unit of 16

×

16 dots. Also, the MCU is separated into L*/a*/b*, and the resulting 8

×

8 dots units are called blocks. The sample ratio called 4:1:1 means the information returned when L* is compared with 4 blocks and a* and b* with one block sections.This a* and b* get information by taking the average value from the 4 pixels around them. This makes use of the characteristic of human eyes that they are sensitive to brightness and insensitive to variations in color.

This process is called sub-sampling.

8.5.2 The JPEG encoding method

The JPEG encoding method (called JPEG below) originated from the group named "Joint Photograph coding Experts Group," which is a technical organization formed by ISO and ITU-T, and is an encoding method which is widely popular in the computer world as a method of compressing full color still image data.

As an outline, JPEG processing compresses images in 3 levels: DCT conversion, quantification, and entropy compression. JPEG decompression makes an image reappear by following the 3-step procedure in reverse: entropy compression, quantification, and reverse DCT conversion. The compression ration of

JPEG image data depends on the type of image, however compression to a degree of 1/7 to 1/30, undetectable to the naked eye, is possible. However, since the parts of the data which do not affect the viewing eye are discarded at the time of compression, it is impossible to restore the image to its 100% original condition when de-compressing. The characteristic of this type of compression is called bad reverse compression method, and is one of the biggest characteristics of JPEG. Other characteristics of

JPEG are emphasis on image quality by change in sample comparision and quatization paramaters, and the merit of being able to choose the compression ratio at the time of compression.

Discrete Cosine Transformation (DCT)

DCT is a transformation by the below method.

DCT Transformation

NOTE

Reverse DCT transformation

Figure 2-44 Discrete Cosine Transformation

For an 8

×

8dot image, DCT transformation dissects the image into cos(n

π

/16),

(n=0,1,2,.....,7) wavelengths both length-wise and width-wise.

For natural images such as pictures etc., when doing wavelength dissection in this way, it has the property of concentrating a comparatively small number of pixels, and giving the other pixels a value close to zero. Even if the pixels close to zero approximate zero, the an image close to the original image can be made to reappear by only the left over pixels. When this transformation is done, low frequency elements gather at the upper left, and high frequency elements at the lower right.

2-71


The characteristics of the JPEG method which are used in ITU-T color communications are shown below.

(1) Can effectively compress data for natural images to that the image quality is minimally affected.

(2) Little noise appears on the boundaries of such images as images and text with borders, monochrome illustrations, etc., and artificial images with clear contrast.

(3) Color spacing adopted from the CIELAB method.

(4) For compatibility with Faxes which do not the width of the scan when starting to scan, a 0 is inserted in the section which shows the number of lines in the scanning width, which is in the SOF0 marker in the JPEG header, and transmission begins. The scanning width is conferred to the receiving side by the addition of a code to the end of the JPEG data which determines the number of lines in the scan, called the DNL marker, which is added to the compressed image data after transmission.

(5) In order to tell the receiving side that it is an image compressed by the G3 facsimile, information such as "G3FAX" as an application name, "200dpi" as a resolution, etc. is set in the JPEG header APP1 marker.

JPEG data is composed of a header section which includes several pieces of information which are necessary for decompression of the image, as well as the section containing the data of the image itself, which is DCT transformed, quantified, and entropy compressed. The header section is comprised of several tables called segments, and 2 bytes of encoding, called a marker, which show the contents of the table, are attached at the head of the segment.

Markers are expressed by "0xFF" and the 1-byte combinations of values peculiar to each marker, so by reading these, the marker and its connected paramaters can be interpreted. These markers are defined by

ITU-T T.81.

8.5.3 Image processing outline

(1) Images scanned by the color contact sensor are read into memory as RGB data.

(2) The read RGB data undergoes color transformation processing, and is converted to L*a*b* data.

Also, after this processing, it is changed into 16x16dot elements called MCU.

(3) Using the fact that the human eye is sensitive to changes in brightness and insensitive to changes in color, the resolution of a* and b* is roughened and the amount of information lessened without affecting the image which is seen by the human eye.

(4) Each block undergoes DCT transformation and the image data is separated into 64 cos waves.

(5) Photos of natural images, etc, have characteristically high numbers of low-frequency elements and low numbers of high-frequency elements. Because of this, an operation table (quantization parameter) is used in which low-frequency elements are left and high-frequency elements are reduced, and unnecessary sections are compressed.

(6) The compressed data is made in a single dimension facing from the upper left to the lower right., and this is encoded with Huffman encoding using a special Huffman table.

(7) The data which has finished being encoded is transmitted in ECM mode using a modem.

(8) At the receiving side, the original image is decompresses using the information in the JPEG image header. First, decoding is done using the Huffman table included in the header. After that, the image is made in two dimensions, facing from the lower right to the upper left.

(9) Reverse quantization is performed using the quantization parameter in the header. During quantization, the high-frequency elements which have little effect on the image seen by the eye are lost, so the original data is not perfectly restored.

(10) Inverse Dispersal Cosine Transformation (IDCT) is performed, transforming into L*' a*' b*' data.

Sub-sampling is done at the time of transmission, so the amount of a*', b*' data is 1/4 that of l*' data.

(11) The L*'a*'b*' data has color transformation processing done, is converted into RGB data (R'G'B'), and stored in memory.

(12) The converted RGB data is transformed into dual-value CMYK data for printing, and printed out with the BJ printer assembly.

The receiving side declares with the DIS signal that it has the ability to communicate in color conforming to the ITU-T standards and that it supports the JPEG encoding method. After confirming the receiving machine's ability to communicate in color, the transmitting side gives instructions to receive as a JPEGcompressed color image with DCS.

After this, error-free transmission of the JPEG-encoded image data is done by the interior modem with high-speed data communications following the ECM procedure.

8.5.6 Operations where other machine does not have color communications ability

When sending a color FAX where the other machine does not have color communications ability, this machine informs the user by displaying "TRY AGAIN IN B/W" (#085).

In other words, it judges whether or not the other machine can receive in color according to the DIS from the receiving machine. It does not automatically switch to BW and re-send. The following measures are necessary for the user to deal with this situation depending on the other machine.

1. When the other machine is a BW FAX

The other machine can only receive BW images, so re-send as a normal BW Fax.

2. When the other machine is an ITU-T color communications-compatible FAX

The other machine is set to disallow color reception, or it is possible that color reception temporarily cannot be done for some reason, so re-send after having the other party check the settings and set them to allow color communication.

8.5.7 Conditions necessary for color reception

User data, types of installed cartridges, etc. Determine whether or not this machine can receive in color as a transmitting machine. A necessary condition is that COLOR RX be set to ON .

Condition 1 : With COLOR RX ON and MEMORY RX OFF

Receives in color when printing can be done with a BC-21e cartridge installed. Color reception cannot be done if a cartridge other than a BC-21e is installed, or if a no color ink error has been detected, etc.

Condition 2: With COLOR RX ON, MEMORY RX ON

If memory reception is possible, memory reception can be done in color regardless of the type of cartridge installed.

When the settings in Desktop Manager are set to forward received data to a PC, memory reception can be done even if MEMORY RX is OFF .

NOTE

NOTE

Forced printing using a cartridge other than a BC-21e BJ cartridge

Images received by color transmission cannot be automatically printed with a BJ cartridge other than the BC-21e. If a cartridge other than the BC-21e is installed,

"CHANGE BC-21e" will be displayed, and memory reception will be done. With this machine, color images received by memory reception may be output according to the user operation. Output of images is done by choosing the desired TX/RX No. from the

Memory reference function's PRINT DOCUMENT menu.

2-76


8.5.8 Specifications for Color Communications

The operations for color communications shown below are specifications, so please take care when fielding questions from users.

Transmission Specifications

· Even if the Color/Black button is pressed and the display changed between pages during transmission, pages of BW images and pages of Color images cannot be mixed.

· Image transmission of JPEG grayscale is not possible.

· Even when ECM TX settings are OFF , this setting is ignored for color transmission, and transmission is done automatically by ECM.

· The TTI header attached to the head of the color image is an image compression specification added when scanning, so the time is the scanning time, not the time that transmission actually begins. This differs from BW transmission.

· Two types of transmission mode for color transmission can be chosen: STANDARD and FINE. These are changed by the compression ratio, depending on the quantization parameter. This varies according to the image, but transmission in STANDARD takes approximately half the time compared to FINE mode.

Reception Specifications

· In the TX REPORT settings, even when PRINT WITH IMAGE is set to ON , the color-transmission image is not attached. Instead a "The color fax image is not printed on this report" message is printed.

· Grayscale JPEG images sent from machines of other companies can be received.

· When an error indicating no color ink appears, a BW FAX is not automatically output even if there is black ink available.

· When the ECM RX setting is OFF , color reception is not performed.

Other Specifications

· With framed tables, text, monochrome illustrations, etc. And sharp contrast artificial images, a small amount of noise may occur in the image border.

· Color transmission are not supported in V3.01 of Desktop Manager.

· Because RX REDUCTION becomes ON when the default setting BOTTOM MARGIN is set to

NORMAL , the scanning width is reduced.

NOTE

Automatic adjustment of CS LED lights-on duration

The CS LED lights-on duration, which can be adjusted via button operation, is also adjusted automatically in the following cases:

• When power is turned ON then SRAM data is corrupted

When this product is shipped, after factory adjusment of the CS LED light-on duration, the exposure control data is stored in SRAM. Because this data is preserved by the Lithium battery even if the power supply is shut off, further adjustment is unnecessary in almost all cases. When the machine’s power switch is turned on, the data stored in SRAM is checked for correctness by Checksum, and if any data in

SRAM has been lost, adjustment of CS-LED lights-on duration is automatically performed at that time. At first, a check is done for the presence/absence of a document, and if there is no document, exposure control is performed automatically.

Exposure control data measured after this is stored in SRAM. When a document is present, scanning is done in an error condition, an abnormal image is output, and the contact sensor is aware that there is an abnormality.

This adjustment is used to eliminate uneven scanning which can result from variations in light intensity between individual LED’s. Performing the adjustment will therefore have an effect on scanned and copied images.

The adjustment value is registered in an SRAM IC which has lithium battery back-up and will not be lost even if power is turned off. However, the SRAM data can become damaged, for example by battery depletion. In this case, the machine checks the data’s validity the next time power is turned ON. If the data is invalid, the adjustment is made automatically. If, at this time, the DES detects a document, an abnormal image is output, and the contact sensor is aware that there is an abnormality. After the document is removed, the message PRESS Start/Scan is displayed. When the Start/Scan button is pressed, the machine performs the adjustment once again. Because the user is automatically prompted, it is almost never necessary to perform this adjustment during normal use. However, if the SPCNT board,

Contact sensory ass’y, or lithium battery is replaced, be sure to perform this adjustment. Also, if the color or brightness of scanned or copied images is faulty, performing this adjustment may correct the problem.

b) Procedure

(1) Check that the operation panel is closed correctly, then perform the adjustment by following the steps described below .

Set BA PATTERN PRINT Set Printing the Test Pattern.

Figure 3-3 Printing the Test Pattern

The test pattern can be printed only when Black BJ Cartridge (BC-20) and Color BJ

Cartridge (BC-21e) are used. Photo Color BJ Cartridge (BC-22e) cannot be used.

NOTE c) How to read the Test pattern

As shown in Fig. 3-5 , the test pattern shows the SHQ, SHQ2 (Not used), HQ (normal mode), HS

(economy mode) and uni-direction printing condition from the top. The respective vertical lines for HQ and HS can be moved left or right on the second row (of three rows). As shown in Fig. 3-6 , adjust so that the vertical lines in the middle are correctly aligned.

Figure 3-5 Correct Test Pattern d) Correction procedure

The misaligned vertical lines in the middle, shown in Fig. 3-6 , are described below.

(1) Check the correction direction for the 2nd line, and check the dot count. (In the example, a 2-dot correction to the right is necessary.)

(2) Determine the dot count required for the correction.

In SHQ, the dot count is roughly 4.55 times. (E.g., 2

×

4.55 = 9)

In HQ, the dot count is roughly 2.86 times.

(E.g., 2

×

2.86 = 6)

In HS, the dot count is 2 times.

(E.g., 2

×

2 = 4)

(3) As shown in Fig. 3-7 , make the correction for all print mode. (The flowchart shows the procedure for making a 2-dot correction to the right for the all print mode, respectively. The actual display may look different from the figure.)

(4) After making the correction, print out the test pattern. If there is any misalignment, do the correction again.

Example: A 2-dot correction on the right is necessary

[Parameter 10]

The "wait time after transmission of a dialing signal ends until a significant signal is detected in transmission" was set as T1 timer with parameter 10.

However, ITU-T recommends that it should be set as T0 timer, so parameter 10 has been renamed to

T0 timer and the default time-out time has been changed from 35 to 55 seconds.

The T1 timer for the transmitter (wait time after a CED, V21 flag, or ANSam significant signal is detected until the next significant signal is detected) is fixed at 35 seconds.

NOTE

[Parameter 11]

Set the T1 timer for the receiver (wait time after DIS transmission starts until a significant signal is received).

If frequent errors occur during reception (2 instances) because of line connection conditions, raise the value of this parameter.

[Parameter 13]

Set the maximum time to receive one line of image data when image data is received.

If the other party is a computer fax and the time to receive one line of image data is long, raise the value of this parameter to increase the maximum reception (2 instances) time.

[Parameter 13]

Sets the bottom margin for color printing. The margin used when PRINT AGAIN in user data is set to NORMAL can be changed by this parameter when color printing. However, when the trailing edge of the recording paper passes through the pinch roller when the margins have been narrowed, there are cases where a small amount of color shift occurs at the bottom edge of the image.

3. INK ABSORBER CAPA

This switch allows the waste ink capacity stored in the SPCNT board to be checked or entered.

[SUCTION]

This allows the waste ink capacity for the ink absorbed during cleaning to be checked or entered.

When entering the waste ink capacity, use the numeric buttons to enter a value 0 to 100 (%).

USER'S GUIDE .

1.1 Setting up

• Choosing a Location for Your MultiPASS

• Do you have everything?

Check that nothing is missing when the unit is unpacked.

• Removing shipping materials

Peel off all strips of tape from the unit. Don't forget to remove the protective sheet from the separation roller, in the scanner section.

• Assembling your MultiPASS

Install the accessories, Document Support, Document Tray, etc.

• Making connections

Connect the Telephone line, Extension phone or Answering machine or Data Modem, Parallel cable (for

PC).

• Powering up

Connect the power cord and check that power is supplied.

• Installing the BJ cartridge

Unseal the BJ cartridge, and load it into the machine. The instructions for this operation are written on the printer cover.

• Loading paper

Set paper in the auto sheet feeder, in PAPER SIZE under PRINTER SETTINGS , set the size of paper that is to be used.

• Setting the TEL LINE TYPE

Choose the setting the matched the type of line being used.

• Entering user information

Enter user information, such as DATE & TIME, UNIT TELEPHONE #, UNIT NAME .etc.

1.2 Checking Operations

• Copy operation

Make a copy, and check that the operation is normal.

• Communication test

Transmit to, and receive from other facsimiles, and check that images are sent normally for transmission, and are printed normally for reception.

What to do when trouble occurs

Very rarely, during use, the display may go out, all the buttons may stop working, or some other trouble may occur because of strong electrical noise or a large amount of static. If such trouble occurs, initialize the RAM. During installation, we recommend that you perform the all clear operation after the power on. Refer to NOTE: "All clear" when nothing works on Page 1-61 .
