1-2 Precautions on Disassembly and Reassembly

Very careful precautions should be taken when replacing parts. Before replacing, please check cables because you cannot put the cables that you removed for replacing parts into the proper place if you would not make sure of where they were connected and in which condition.

Please do the following before disassembling for a repair or replacement of parts.

1. Pull out paper cassette, printer cartridge installed.

Especially careful not to be scratched by the surface of developer or not to expose them to light.

2. Turn the power switch off.

3. Take out the power plug, printer cable from the printer.

4. Use only the same type of part as original when replacing parts.

5. Do not force to open or fasten plastic material components.

6. Be careful that small parts such as screws should not get in the printer.

7. When disassembling, assembling, also observe small components are located in place.

8. If you uncover and turn the machine over to replace some parts, toner or paper particles may contaminate the LSU window. Protect the LSU window with clean paper.

Releasing Plastic Latches

Many of parts are held in place with plastic latches.

The latches break easily : release them carefully.

To remove such parts, press the hook end of the latch away from the part to which it is latched.

1-1

Precautions

1-3 ESD Precautions

Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called

“Electrostatically Sensitive (ES) Devices”, or ESDs.

Examples of typical ESDs are: integrated circuits, some field effect transistors, and semiconductor “chip” components.

The techniques outlined below should be followed to help reduce the incidence of component damage caused by static electricity.

CAUTION:

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

1. Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commercially available wrist strap device, which should be removed for your personal safety reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with

ESDs, place the assembly on a conductive surface, such as aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assembly.

3. Use only a grounded tip soldering iron to solder or desolder ESDs.

4. Use only an “anti-static” solder removal device. Some solder removal devices not classified as “anti-static” can generate electrical charges sufficient to damage ESDs.

5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage ESDs.

6. Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a comparable conductive material.

7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed.

8. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until completely plugged or soldered into the circuit.

9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the brushing together of clothing fabric and lifting one’s foot from a carpeted floor, can generate static electricity sufficient to damage an ESD.

4-1-5 Modem and TX-and RX Related Circuits

MODEM

The Conexant™ FM336 modem is a V.34 half-duplex modem that supports Group 3 facsimile send and receive speeds up to

33600 bps using the V.34 half-duplex mode. Using a V.34 technique to optimize modem configuration for line conditions, the modem connects at the optimal selected data rate that the channel can support from 33600 bps to 2400 bps.

The modem can operate over the public switched telephone network (PSTN) through a line terminator provided by a Data

Access rrangement (DAA). The modem satisfies the requirements specified inITU-T recommendations V.34, V.17, V.29, V.27

ter, V.23, V.21, and meets the binary signal ingrequirements of V.8 and T.30. Internal HDLC support eliminates the need for an external serial input/output (SIO) device in the DTE for products incorporating error detection and T.30 protocol. The modem can perform HDLC framing per T.30 at all data speeds. CRC generation/checking along with zero insertion/deletion enhances

DLC/HDLC frame operations. An FSK flag pattern detector facilitates FSK detection during high speed reception.The modem features a programmable DTMF transmitter/receiver and three programmable tone detectors which operate in the tone mode.

The modem offers lower power consumption and small size to allow the design of compact system enclosures for use in industrial, office, and home environments.The modem is available in a 100-pin PQFP package.

4-1-7 HOST INTERFACE:

Parallel Port Interface

PARALLEL PORT INTERFACE PART KS32C61100 has the Parallel Port Interface Part that enables Parallel Interface with PC.

This part is connected to PC through Centronics connector. It generates major control signals that are used to actuate parallel communication. It is comprised of/ERROR, PE, BUSY, /ACK, SLCT, /INIT, /SLCTIN, /AUTOFD and /STB. This part and the PC data transmission method support the method specified in IEEE P1283 Parallel Port Standard

(http://www.fapo.com/ieee1284.html).

In other words, it supports both compatibility mode (basic print data transmitting method), the nibble mode (4bit data; supports data uploading to PC) and ECP (enhanced capabilities port: 8bits data - high speed two-way data transmission with PC).

Compatibility mode is generally referred to as the Centronics mode and this is the protocol used by most PC to transmit data to the printer. ECP mode is an improved protocol for the communication between PC and peripherals such as printer and scanner, and it provides high speed two-way data communication. ECP mode provides two cycles in the two-way data transmission; data cycle and command cycle. The command cycle has two formats; Run-Length Count and Channel Addressing. RLE

(Run-Length Count) has high compression rate (64x) and it allows real-time data compression that it is useful for the printer and scanner that need to transmit large raster image that has a series of same data. Channel Addressing was designed to address multiple devices with single structure. For example, like this system, when the fax/printer/scanner have one structure, the parallel port can be used for other purposes while the printer image is being processed.This system uses RLE for high speed data transmission. PC control signals and data send/receive tasks such as PC data printing, high speed uploading of scanned data to PC, upload/download of the fax data to send or receive and monitoring the system control signal and overall system from PC are all processed through this part.

Circuit Description

4-2 OPE PBA

4-2-1 SUMMARY

OPE Board is separated functionally from the main board and operated by the micom(HT48C5A) in the board. OPE and the main use UART (universal asynchronous receiver/transmitter) channel to exchange information. OPE reset can be controlled by the main.

OPE micom controls key-scanning and LCD and LED display, detects documents and senses SCAN position. If there occurs an event in OPE (such as key touch and sensor level change), it sends specific codes to the main to respond to the situation and the main analyzes these codes and operates the system.

For example, it the main is to display messages in OPE, the main transmits data through UART line to OPE according to the designated format and OPE displays this on LCD, LED.

OPE’s sensing is also transmitted to the main through

UART line and then the main drives necessary operation.

OPE PBA consists of U1(MICOM, HT48C5A),LCD, key matrix, LED indicators, SCAN position sensor and the document detect sensor. Refer to OPE Schematic Diagram and

Wiring Diagram sections of this manual.

• Display from the controller is received at U2 pin 47

(RX DATA).

• LCD drive signals are sent from P1-x pin group, P1-4~P1-

14 pins.

• Machine status LED drive signals are sent from U2

LED0~LED4.

• Document detect sensor output is received at U2 pin 1.

• Scan position sensor output is received at U2 pin7

Circuit Description

4-4-3 Detailed Spec.

TEL_LINE INTERFACE CIRCUIT

1) TEL_LINE INTERFACE CIRCUIT

• It is an interface that physically connects facsimile to the PSTN (public switching telephone network) through TIP and

RING as in fig. 1.

• ARS 1-3 protects the system from voltage overload such as the surge coming through PSTN. ARS 2 and ARS 3 are used as overload protection in common mode (between TIP/RING and FRAME GROUND). ARS 1 is used as overload protection in normal mode (between TIN and RING) and it uses ARRESTOR for 600V. However, arrestor’s rated voltage differs from European and USA(400v).

• CML (CONNECT MODEM to LINE) RELAY K1 is a switch designed to selectively connect the PSTN to system voice communication path and fax communication path. In STAND_BY MODE and voice communication mode, it is connected to

TEL PART and FAX PART while communicating and dialing.

• CML Relay (K1): CML relay interfaces with T2(600:600) TRANS in communication mode.

• DC Impedance: DC impedance is determined in the DC Feeding Unit. It represents DC characteristic of the computer connected through -48V DC power of the switch and lines. The DC characteristic of required by the communication standards of a number of countries is the DC resistance of 50

Ω

~300

Ω to the current range of 20mA~120mA. (value varies depend on countries).

• AC Impedance or Return Loss: AC impedance is determined by the peripheral circuits of T2 Transformer. It is the standard required for optimum signal transmission between computer and switch. When the AC impedance of the computer for AC signal transmission and the AC impedance of the switch matches, the signal can be transmitted without loss.

Therefore, communication standards specifies the AC impedance of the computer and it implies the return loss. The communication standards of each country, considering the characteristic of their lines, requires 600

Ω or the return loss of 14dB and higher against the AC impedance of Complex and the AC signals of 300Hz~400Hz. The AC impedance of transformer changes depending on the load resistance, the core material, coil inductance and resistance, but generally its characteristic against load resistance is considered.

Circuit Description

RINGER DIAL CIRCUIT

1) Ringer Circuit

• The ring detect circuit detects the ring signal by sending the bell signal sent from PSTN to the primary photo coupler

(PC814). At this point, C(1uF/250V) is used to match the ring impedance and R is coupled directly in order to prevent any damage to the photo coupler due to ring voltage.

2) Dialing Circuit

• Dialing circuit is initiated only when the power is on and it is transmitted to line through the modem of main part (T2 trans)

3) External Hook Detect Circuit

• In the discrete LIU method, the external hook detect circuit is designed to use both the photo coupler and current detector in order to be used in all countries including the countries with low series resistance (Germany, Switzerland, Belgium,

Austria, etc.). To use photo coupler (PC814), you must carefully select the resister connected parallel (75

Ω

) to the photo coupler in order to satisfy the voltage drop standards of England and a few other countries. The diode connected to the current detector pin (5/6) was used to detect the external hook all through when the line parity turns over.

4) Recall Circuit

• In the discrete LIU method, we used the recalling method using low cost photo coupler instead of using photo MOS relay in order to initiate the recalling for handset hook off dialling after the power is turned on. In this case, the time break recall was enabled by switching the power transistor of the telephone circuit using the secondary CPU control.

Circuit Description

4-4 Engine PPA

4-4-1 Engine Configuration

4-4-1-1. Video Controller Board

Video Controller Board receives image data from the host computer and converts it into bitmap (binary) image or receives bitmap image directly from the host computer and sends it to the engine controller board.

4-4-1-2. SMPS Board

It basically receives AC input and generates ripple-free DC level +5V and -5V +24V. Next, it supplies these voltages to each unit appropriately.

It also supplies AC power to heat lamp of fixing unit.

4-4-1-3. HVPS Board

HVPS board generates high voltages of THV/MHV/Supply/Dev and supplies them to the developing unit to create images. It is designed to realize optimum conditions for the images.

This board includes LSU interface unit and cover open sensing unit that it intercepts +24V voltage to the main motor, LSU, fan, clutch and fixing unit when you open the front cover.

4-4-1-4. Developer

Using the digital picture process, developing unit generates visible images. It is comprised of charge roller, OPC drum, developer roller, supply roller and toner.

4-4-1-5. LSU (Laser Scanning Unit)

This is controlled by engine controller. Using laser beam control, exposure of OPC drum and the rotational principle of polygon mirror, it forms electro-static latent image in the OPC drum with the video data received from engine. It is the core part of LBP.

OPC drum synchronizes with the feeding speed of the paper and rotates. When the laser beam inside LSU reaches at the end of polygon mirror, it generates /HSYNC signal and send it to engine. Then the engine detects /HSYNC signal and adjusts the lengthwise row of the image on the paper. After detecting /HSYNC and after set time period, it sends the video data to LSU to adjust the left margin on the paper.

The one side of the polygon mirror is the one line scanned.

4-4-1-6. Transfer

Transcribing unit is comprised of PTL(pre-transfer lamp) and transcribing roller. PTL detects the beam of the OPC drum, lowers the electric potential of the developing unit and lower the adhesiveness of toner to enhance transcription coefficient.

And the transcribing roller transfers the toner (constituting element of video image) on OPC drum to the paper.

4-4-1-7. Fixer

It is comprised of heat lamp, heat roller, pressure roller, thermistor and thermostat. It fixes the toner powder transferred to the paper on the paper using pressure and high heat in order to finish the final printing job.

4-27

Circuit Description

4-4-2. Developing Process

4-4-2-1 Feeder

Engine operates this unit. Solenoid rotates the feed roller and feeds one paper. Then the paper is fed into the set and hits the actuator of the feed sensor. At this point, the engine detects the signal and prepares to spray according to the image data. If any problem happens to this feed sensor operation, the system displays “paper jam error” on the OP panel.

Also, feed sensor unit is closely related to the paper margin.

4-4-2-2. Electrifier

This unit electrifies consistent negative voltage to OPC. When the high negative voltage (-1550V) is allowed to charge roller, the OPC drum surface will be consistently electrified with approximately +1300V. This is the first process in generating the digital picture.

4-4-2-3. Exposer

After receiving bitmap image data from engine board, LSU turns the laser diode either on or off depending on whether the digital data is present or absent in order to expose the OPC drum with the switched laser beam data. The difference between the voltages generated at this point is presented above. In other words, the part exposed to the laser will have -50V and its relative electric potential will increase and form electrostatic latent image.

The part unexposed to the laser as it did not have the video data will consistently retain -800V. Eventually, the image will form in the part electrified and rose to -50V(forms black dot) and the part retaining -800V will be white in order to make the basic condition to form the video data.

4-4-2-4. Developer Unit

On the surface where OPC drum and developer roller (rotate in opposite direction) meet, the toner that has negative electric characteristic moves to the exposed part (-50V) due to the electric potential difference, but it will not move to the unexposed part (-800V).

Toner on the OPC drum is transferred to paper by transfer unit. In other words, the toner on the OPC drum surface is inducted by the transfer roller electrified to approximately +1.3KV(600~2800V variable) to the paper.

At this point, the voltage (600~2800V variable) is determined by temperature and humidity.

The above process is called “transfer”.

4-4-2-6. Anchorage unit

The toner transferred on to the paper is at the electronically low state and it can be easily scattered. Considering this fact, we used heat (180°C) and pressure (4kg) to fix the toner on the paper permanently. Then the image formed will remain on the paper permanently. Heat roller transfers the heat from the heat lamp inside to the paper. The surface of the heat roller specially coated with Teflon repels toner melted by the heat from the surface.

The pressure roller on the bottom of the heat roller is made of silicon resin and its surface is also coated with Teflon. The thermistor of the fixer unit detects the surface temperature of the heat roller and feeds this information back in order to retain 180°C while printing and 135°C, while on standby. The thermostat is used as the secondary safety device and it prevents overheat by shutting the main power when the heat lamp is overheated.

4-4-2-7. Exit

After the digital picture process is finished, the printed paper will come out of the set through the exit sensor. The signal detected will be transferred to the engine and provide the position information. If the actuator and the sensor do not work normally, the system will display “Paper Jam 2 Error”.

Circuit Description

4-4-2-8. MHV (Electrification Output Enable)

Electrification Output Enable is the electrification output control signal 'PWM-LOW ACTIVE'.

When MHV-PWM LOW signal is received, Q401 turns on and the steady voltage will be accepted to the non-inverting terminal of OP-AMP 324. As the voltage higher than the inverting reference voltage of OP-AMP, which is set to R405 and R406,

OP-AMP output turns high.

This output sends IB to the TRANS auxiliary wire through current-restricting resistance Q402 via R408 and C403 and Q402 turns on. When the current is accepted to Q402, Ic increases to the current proportional to time through the T401 primary coil, and when it reaches the Hfe limit of Q402, it will not retain the "on" state, but will turn to "off". As Q402 turns 'off', TRANS N1 will have counter-electromotive force, discharge energy to the secondary unit, sends current to the load and outputs MHV voltage through the high voltage output enable, which is comprised of Regulation– circuit.

4-4-2-9. BIAS (supply/dev output unit)

BIAS voltage output is generated only when electrification voltage is set to output. In the circuit presented above, it organizes enough zener-diodes required to output dev/supply voltage from electrification output.

Supply voltage is output when the supply-ea signal is 'L'. When supply-ea is 'L', Q104 turns off and as Q105 does not turn on, the electric potential of the output unit retains the electric potential of zener and thus -500V is output as the supply voltage.

In case supply-ea signal is 'H', both Q104 and Q105 will turn on and the electric potential of the output unit will not retain the electric potential of zener and become GND level and thus the output voltage will become .

The output condition of developer voltage is the same as that of the supply voltage.

4-4-2-10. THV(THV(+)/THV(-) Output Unit)

Transfer(+) output unit is the transfer output control signal 'PWM-LOW ACTIVE'.

When THV-PWM LOW signal is received, Q203 turns on and the steady voltage will be accepted to the non-inverting terminal of OP-AMP 324. As the voltage is higher than the inverting reference voltage of OP-AMP, OP-AMP output turns high.

The 24V power adjusts the electric potential to ZD201 and ZD202, sends IB to TRANS auxiliary wire through current-restricting resistance R215 via R212 and C204, and eventually Q204 will turn on. When the current is accepted to Q402, Ic increases to the current proportional to time through the T201 primary coil, and when it reaches the Hfe limit of Q204, it will not retain the "on" state, but will turn to "off". As Q402 turns 'off', TRANS N1 will have counter-electromotive force, discharge energy to the secondary coil, sends current to the load and outputs THV voltage through the high voltage output enable, which is comprised of Regulation– circuit. The output voltage is determined by the DUTY width. Q203 switches with PWM DUTY cycle to fluctuate the output by fluctuating the OP-AMP non-inverting end VREF electric potential, and the maximum is output at 0% and the minimum, at 100%.Transfer(-) output unit is THV-EA 'L' enable.

When THV-EA is 'L', Q302 turns on and the VCE electric potential of Q302 will be formed and sends IB to TRANS auxiliary wire through R311, C305 and VR302 via current-restricting resistance R314, and eventually Q303 will turn on. When the current is accepted to Q303, Q303's Ic increases to the current proportional to time through the T301 primary coil, and when it reaches the Hfe limit of Q303, it will not retain the "on" state, but will turn to "off". As Q303 turns 'off', TRANS N1 will have counter-electromotive force, discharge energy to the secondary coil, send current to load and output THV(-) voltage through the high voltage output enable, which is comprised of Regulation– circuit.

Circuit Description

4-4-2-11. Environment Recognition

THV voltage recognizes changes in transfer roller environment and allows the voltage suitable for the environment in order to realize optimum image output. The analog input is converted to digital output by the comparator that recognizes the environmental changes of the transfer roller. It is to allow the right transfer voltage to perform appropriate environmental response considering the environment and the type of paper depending on this digital output by the programs that can be input to the engine controller ROM.

For ML-5000 or ML-5200 series, this environment recognition setting is organized as follows: First, set the THV(+) standard voltage. Allow 200M

Ω load to transfer output, enable output and set the standard voltage 800V using VR201. Then set 78

(CPU's recognition index value) as the standard using VR302. This standard value with CPU makes sure that the current feedback is 4µA when output voltage is 800V and load is

200M

Ω

.If the load shows different resistance value when 800V is output, the current feedback will also be different and thus the index value will also be different. according to the index value read by CPU, the transfer voltage output will differ according to the preset transfer table.

The changes in transfer output required by each load is controlled by PWM-DUTY.
