GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND

SERVICE FOR DP1600/2000/2500 AND GD-1060

The installation and service should be done by a qualified service technician.

1. Transportation

• When transporting/installing the copier, employ two persons and be sure to use the positions as indicated below.

The copier is fairly heavy and weighs approximately 50 kg (110 lb), therefore pay full attention when handling it.

4 portions

2. Installation

• Be sure to use a dedicated outlet with AC 115 or 120V/15A (220V, 230V, 240V/10A) or more for its power source.

• The copier must be grounded for safety.

Never ground it to a gas pipe or a water pipe.

• Select a suitable place for installation.

Avoid excessive heat, high humidity, dust, vibration and direct sunlight.

• Also provide proper ventilation as the copier emits a slight amount of ozone.

• To insure adequate working space for the copying operation, keep a minimum clearance of 80 cm (32") on the left, 80 cm (32") on the right and 10 cm (4") in the rear.

• After having installed the copier, be sure to push the carrying handles into the copier.

3. Service of Machines

• Basically, be sure to turn the main switch off and unplug the power cord during service.

• Be sure not to touch high-temperature sections such as the exposure lamp, the fuser unit, the damp heater and their periphery.

• Be sure not to touch high-voltage sections such as the chargers and the high-voltage transformer.

• Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fans, etc.

• When servicing the machines with the main switch turned on, be sure not to touch live sections and rotating/operating sections. Avoid exposure to laser radiation.

• Use suitable measuring instruments and tools.

January 2001 © TOSHIBA TEC GD-1060 GENERAL PRECAUTIONS

• Avoid exposure to laser radiation during servicing.

– Avoid direct exposure to beam.

– Do not insert tools, parts, etc. that are reflective into the path of the laser beam.

– Remove all watches, rings, bracelets, etc. that are reflective.

4. Main Service Parts for Safety

• The breaker, door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly important for safety. Be sure to handle/install them properly.

5. Cautionary Labels

• During servicing, be sure to check the rating plate and the cautionary labels such as “Unplug the power cord during service”, “Hot area”, “Laser warning label” etc. to see if there is any dirt on their surface and whether they are properly stuck to the copier.

6. Disposition of Consumable Parts/Packing Materials

• Regarding the recovery and disposal of the copier, supplies, consumable parts and packingm a terials, it is recommended to follow the relevant local regulations or rules.

7. When parts are disassembled, reassembly is basically the reverse of disassembly unless otherwise noted in this manual or other related documents. Be careful not to reassemble small parts such as screws, washers, pins, E-rings, toothed washers in the wrong places.

8. Basically, the machine should not be operated with any parts removed or disassembled.

9. Precautions Against Static Electricity

• The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband, because the ICs on it may become damaged due to static electricity.

Caution: Before using the wrist band, pull out the power cord plug of the copier and make sure that there is no uninsulated charged objects in the vicinity.

Caution:

Dispose of used batteries and RAM-ICs including lithium batteries according to the manufacturer's instructions.

Attention: Se débarrasser de batteries et RAM-ICs usés y compris les batteries en lithium selon les instructions du fabricant.

Vorsicht:

Entsorgung des gebrauchten Batterien und RAM-ICs (inklusive der Lithium-Batterie) nach Angaben des Herstellers.

2.2.3 Print mode

The machine provides various print modes to meet various requests from users, such as applicable recording paper types, recording methods, etc.

2.2.4 Recording paper selection algorithm and print algorithm

A) Recording paper selection algorithm

Capable of identifying the above-mentioned recording paper size of a received image, this machine prints on the recording paper of the same size as when sent, as a rule. If no recording paper of the identified size is not available, it selects recording paper for printing according to the set mode. The mode is set by using Func. 15 bit 3.

(1) Automatic reduction mode (Func. 15 bit 3 = 0, Default)

Selects recording paper on which the received document can be printed and prints on it.

(2) Reduction OFF mode (Func. 15 bit 3 = 1)

Selects recording paper on which the received document can be printed in a full size.

B) Print algorithm

A reception print image is basically printed on one page. Consequently, the algorithm of reception print is in the order of same size print, discard extra, vertical reduction print, and divided print.

(Refer to the reception print flowchart.)

(1) Discard printing

Func. 15 bit 2 permits selecting between ON and OFF of the option for discard extra.

Func. 15 bit 2 = 0 : OFF

Func. 15 bit 2 = 1 : ON (Default)

Func. 15 bits 6 and 7 allow the discard parameter to be set.

• When the option for discard extra is ON:

When the length of the received document in the feed direction exceeds the effective recording area and the part exceeding one page is within the discard parameter, printing takes place with the exceeding part discarded. When the length of the received document in the feed direction exceeds the discard parameter range and is within the reduction range of the maximum reduce ratio, vertical reduction print takes place. When it is not within the reduction range of the maximum reduce ratio, divided print takes place. The discard extra takes preference over the vertical reduction print.

A: Effective recording area

B: Record data length outside effective recording area

B

If the length of B is less than the set discard parameter, B is discarded.

• When the option for discard extra is OFF:

The vertical reduction takes preference without performing discard extra print.


(2) Vertical reduction print

Func. 15 bit 5 permits selecting between ON and OFF of the option for Vertical reduction print.

Func. 15 bit 5 = 0 : OFF

Func. 15 bit 5 = 1 : ON (Default)

• When the option for Vertical reduction print is ON:

When the length of the received document in the feed direction exceeds the effective recording area, the feed length is reduced in an appropriate reduce ratio and then the received document is printed on one sheet of recording paper.

The following two patterns of maximum reduce ratio are available according to the setting of

Func. 15 bit 1.

Func. 15 bit 1 = 0 : Max. reduce ratio 90 %

→

The reduce ratio settings of 95% and 90 % are valid.

Func. 15 bit 1 = 1 : Max. reduce ratio 73 %

→

The reduce ratio settings of 95 %, 90 %, 86 %,

80%, 83 % and 73 % are valid.

• When the option for vertical reduction print is OFF:

When the length of the received document in the feed direction exceeds the effective recording area, divided print takes place.

(3) Divided print

When received data cannot be recorded on one sheet, even if reception reduction and reception discard are carried out, the recorded data is divided in the vertical direction and printed on two or more sheets with maximum length set up in the copier, without reduction.

If a long original with length of 216 mm which cannot be recorded on one B4 sheet with the maximum reduction is received, when A4, B4, and A5 paper is loaded in the first, second, and third cassettes, respectively, for example, the maximum recording paper (B4) is selected and received data is divided and printed on two or more sheets without reduction (see Table 5-2-2).

Ex.1 Divided into two sheets Ex.2 Divided into three sheets


(4) Similar reduction print

When recording paper of the same size as that of the received document is not available due to running out of paper or no paper is available to cover the received document, the received document is similarly reduced and printed on recording paper smaller than the received document.

Ex.1 To print A3-size received document on an A4-R sheet because of running out of paper.

Similar reduction

A

B

C

A

B

C

A4-R

A3

(5) Rotation print

When recording paper of the same size as that of the received document exists but the orientations are different on those sheets, the received document is rotated by 270 degrees before being printed. The rotation function is performed after discard extra, reduction or dividing processing.

The rotation function is valid for received documents of A4, LT, A5, and ST-R sizes.

(6) Printing with no recording paper

When recording paper has run out during printing, printing takes place on another printable recording paper starting from the next page, if available. However, if recording paper has run out in the middle of divided print, reprinting takes place on another recording paper starting from the first one of the divided pages. (The same operation is done when recording paper of the same size is set in a different paper cassette.)

For the selection order of recording paper, refer to Table 2-2-1.


(7) RTI

When printing a received document with the RTI setting ON, RTI is printed on each page but RTI is printed on the first page only in the case of divided print.

(ON or OFF of RTI is possible by means of the user setting. Default: OFF)

RTI is created for the LT or A4-R width. When printing RTI on A5, B5 and ST-R smaller than those sheets, the information to be printed is reduced to a printable length.

• LT size or up

• A5, B5, ST-R


(8) Received document and selection of recording paper

The procedure for selecting recording paper handled by this machine is briefly described below.

Recording paper for reception print is selected according to the print recording paper range and priority as listed in Table 2-2-1. A printable print recording paper range is selected according to the scanning width and feed length of the received document. A print recording paper range is selected by taking the discard length and feed reduce ratio into consideration.

Shown is an example where an EU model is used, the discard parameter is 10 mm, the feed reduce ratio is max. 75 %, the scanning width of the received image is A4, the number of lines received is STD or 2000 lines. Since the scanning width is A4, the recording paper range to be selected is one of A5R, A4R, FOLIO, B4 and A3.

Since 2000 lines are converted to 519 mm, a feed length to allow 390 mm to be printed on one page with a max. reduce ratio of 75 % is selected. The recording paper length of A4 is 297 mm, the recording paper length of B4 is 364 mm, and the recording paper length of A3 is 420 mm.

Therefore, an A3 paper range covering 390 mm is selected. After an A3 range is selected, recording paper is selected according to the priority in Table 2-2-1, followed by printing.

3. GENERAL

3.1 Main Functions

This machine has following features.

High-speed scanning:

The GD-1060-NA/TW/AU/EU scans one Letter (A4) size Original page in 1.4 seconds (line density 8 dots/mm x 3.85 lines/mm) and stores it into memory.

High-speed transmission:

The GD-1060-NA/TW/AU/EU uses a V.34 modem designed for 33,600 bps communications.

Multi-access:

Using the multi-access facility, multiple processes can be performed in parallel. Functions, such as transmission reservation during reception, copying during memory transmission/ reception, etc. Maximizing the GD-1060-NA/TW/AU/EU’s high-speed scanning and multi-access capabilities provides maximum office productivity and efficiency. Patterns of the multi-access are as follows:

(1) Scan to Memory during Memory Transmission

(2) Scan to Memory during Reception

(3) Scan to Memory during Substitute Reception

(4) Copying during Memory Transmission

(5) Reception during Copying

(6) Reception during Memory printing

(7) Reception during List printing

(8) Scan to Memory during Memory printing

Statement-R, Computer, A4, A4-R (to NAD model) or A3, A4, A4-R, A5-R, B4, FOLIO, Letter, Letter-

R (to MJD/AUD/ASD/SAD/TWD/CND models) - using a laser beam printer.

Halftone system:

Photographic images are clearly recorded by the 256 grayscales using the error diffusion method.

High resolution mode:

The GD-1060-NA/TW/AU/EU can transmit in ultra-fine mode (406 x 392).

January 2001 © TOSHIBA TEC 3 - 1 GD-1060 GENERAL

Image memory communication function:

Picture data can be stored in the image memory. For a delayed transmission, the picture data created by scanning Originals is stored in the image memory and to be transmitted at the designated time.

Other memory functions include multi-address transmission, substitute reception, ECM communication, etc.

The memory contents will be retained by a backup battery for up to 2 hours if a power failure occurs.

The memory size is 5.7 MB.

75 one touch keys:

The remote party’s address data can be registered to a one touch key. Communication options can be registered for each address. Some one touch keys also operate as direct function access keys. For further details, refer to page 3-9.

300 abbreviated dial numbers:

300 abbreviated dial numbers can be assigned in the range from No. 001 to 999.

Alternate number dialing:

It is possible to assign two facsimile telephone numbers to one abbreviated dial number or one touch dial key (one as the primary telephone number and the other as an alternate telephone number). The facsimile first dials the primary telephone number, then redials if the line is busy until the redialing limit count is reached. It will then begin to dial the alternate number. (Except for Relay/Mailbox/Confidential/

Polling)

Multi-address transmission function:

Transmissions of the same original to multiple addresses (up to 375 addresses) are possible using one operation sequence, in which preset abbreviated dial numbers (300), and one touch dial keys (75) can be used. When the multi-key is specified, key pad dialing of up to 100 locations, is also possible.

Multi-polling reception:

Polling receptions from multiple remote parties (up to 375 parties) are possible using one operation sequence, in which preset abbreviated dial numbers (300), and one touch dial keys (75) can be used.

When the multi-key is specified, key pad dialing of up to 100 locations, is also possible.

Relay transmission request function:

The GD-1060-NA/TW/AU/EU can originate a relay transmission or serve as a relay station in relay transmission transactions.

GD-1060 GENERAL 3 - 2 January 2001 © TOSHIBA TEC

Secure RX:

Secure RX allows reception to memory to secure Originals during unattended periods. The user can select a specific time period and all day (24-hour) operation on selected days. The feature can be activated and deactivated by using a 4-digit security code.

Memory transmission:

Allows you to dial the remote party while scanning the original in memory. The original page data is cleared as the sending of each page is completed. Therefore, the memory is utilized effectively for transmissions. A maximum of 100 jobs of memory transmission are possible.

Public fax box:

An original can be reserved in image memory to be polled by remote stations multiple times. One of its merits is that any remote station (even one with a non-TOSHIBA facsimile) can poll such originals without a password.

Program continuous polling:

By designating the starting interval, time, and day-of-week, an endless polling can be set. Once set, polling receptions are repeated at the same time on the designated day-of-week.

Sub-address communication:

The GD-1060-NA/TW/AU/EU supports communication applications using sub-address (SUB/SEP/

PWD) commands conforming to ITU-T. Sub-address communication is possible by keypad dialing, one touch key dialing, and abbreviated dialing using the sub-address settings in Comm. Options.

Security communication:

For transmissions, the facsimile checks if the telephone number of the remote party’s facsimile CSI matches the number dialed on the unit itself. If it matches, the transmission will start. For receptions, the facsimile checks if the telephone number of the remote party’s TSI matches any number assigned to an abbreviated dial number or one touch key. If it matches, the reception will start. Thus transmissions or receptions with any authorized party will be prevented at the earliest stage.

Substitute reception into memory:

When there is no paper remaining in the cassette(s), when a recording paper jam occurs, the toner is empty, or printing is already in progress, the received data is stored into memory instead of being output to recording paper. When the trouble is corrected, or the active printing job is completed, the received data in memory will then be printed.


Communication options:

If necessary, the function may be changed and options can be selected for page number, line monitoring, turnaround polling, ECM communication and security transmission, etc.

Automatic dialing functions:

(1) Dialing with a time designated

Transmitting a original to a designated party at a designated time.

(2) Redialing

When an automatic dialing has been performed and the destination party is busy, redialing will be repeated as many times as programmed with a certain time interval also programmed.

Cover sheet function:

This facsimile has a facsimile cover sheet preparation feature built in, allowing the operator to enter the destination name, sender name at the time of the original transmission. This cover sheet also allows image data, such as a company logo, to be included.

Account code:

By entering a different account code for each destination at the time of transmission, account codes will identify when, for whom, and to whom a particular facsimile message was sent.

Department code:

Permits assigning 99 department codes to control access and track activity. These codes are set up beforehand, and must be used to access machine functions.

Separator page function:

GD-1060-NA/TW/AU/EU has the feature which divide print jobs (received original) using separator page. Also the customer can program the specified paper cassette for this function.

Auto supplies order

GD-1060-NA/TW/AU/EU has the feature which send a supplies order report to the programmed facsimile number automatically when the terminal detect toner end condition and drum low and/or end condition.

List output:

This allows the operator to print data stored in the memory (reservation list, preset dial number lists, function list, communication journal, transmission report, etc.).


Super power saver mode:

This feature turns off virtually all power to minimize power consumption. Only the sub-MPU remains operation sensing for ringing signals, original insertion, or activation of the [SUPER ENERGY SAVER] key.

Sleep mode:

Reduces power consumption by cutting off power for the fuser during periods when printing is not expected. The fast warm up time ensures the printer section will be ready before a full page of image data can be received.

Recovery transmission:

Originals that have gone through the redial count limit will not be cleared, but stored for a programmed period of time. Such originals can be recovered to be transmitted again.

F-code mailbox/relay box communication:

Bulletin board F-code mailbox transmissions using ITU-T standard protocol is possible. Permitting confidential communications with any other similarity equipped facsimile made by TOSHIBA or some other company.

TCF

• TCF signal

When training is not performed correctly, an error may occur in the picture signal. The Tx station transmits a TCF signal and checks if any error occurs in picture data before the picture data communication to follow. When the Rx station detects an error in the TCF signal, the Rx station sends an FTT signal to the Tx station and request for re-training. When normal, a CFR signal is sent instead.

The modem speed of TCF signal is the same as the training signal, and it transmits all zeros for 1.5

seconds.


4.3 High-speed Transmission Procedure

The V.34 modem recommended by ITU-T (Max. transmission rate: 33.6 Kbps) is used. Therefore, the transmission time of the image data is cut substantially when compared to conventional model.

4.3.1 V.8/V.34 procedure a) Outline

• V.8 is performed as a start up procedure to switch to V.34. V.8 can connect an existing facsimile machine to equipment using data modem or other V series modems. The V.34 modem includes a modem circuit which can also be connected to the previously recommended modems. Therefore, it is downwardly compatible.

• The new techniques such as the pre-emphasis techniques *1 and the probing techniques *2, are fully used. Pre-emphasis techniques not only make the speed of modulation method high, but also gain the S/N ratio. Probing techniques measure the line characteristics and optimize the modem for the line state. Therefore, these techniques do not simply speeding-up transmission momentarily, but do so at the average level when the data transmission is actually performed.

• For V.8 and the pre/post-fax transmission for V.34, the procedure is speeded up by full duplex communication.

• The following 14 types of image transmission speed are available: *3

33.6 kbps/31.2 kbps/28.8 kbps /26.4 kbps /24.0 kbps /21.6 kbps /19.2 kbps /16.8 kbps /14.4 kbps

/12.0 kbps /9.6 kbps /7.2 kbps /4.8 kbps /2.4 kbps

• The modulating speed (baud rate) can be selected from 2400, 3000, 3200 symbol/sec (mandatory), or 2743, 2800, 3429 symbol/sec (option). The data rate can be set more accurately than the conventional modem. *4

*1: A signal is sent by raising the output level in the high-frequency band - in which the noise is relatively loud.

*2: The tone called “Probing Tone” is sent. The receiver measures the line characteristics.

*3: In the ITU-T Recommendation, it is described as “data rate”. “Image transmission speed” is the same as “data rate”.

*4: In the ITU-T Recommendation, it is described as “symbol speed”. “Symbol rate”, “Modulating speed”, and “Baud rate” have the same meaning. This machine cannot use the speed of “2743 symbol/sec”.


Notes: 1. In the V.34 procedure, ECM is used. If the ECM transmission/reception of user data is set to

“Not performed”, the V.8 procedure is not performed. Therefore, the procedure does not switch to V.34, and V.17 or the prior, is selected.

2. Also when the transmission/reception speed is set to 14.4 kbps or less, the V.8 procedure is not performed, and V.17 or the prior, is selected.

3. To switch to the V. 8/V.34 procedure after starting V.21 procedure, see “c-1”.

4. After the V.34 procedure starts, fallback is performed in the V.34 procedure. However, fallback for V.17 mode or before is not performed.

The scanner unit has the exposure lamp’s light irradiated to the original placed for transmission. At this time, it converts the light reflected from the original into electrical signals through the CCD. Then the

A/D converter (IC3) converts the electrical signals into digital signals. The scanner control GA (IC11) converts them into parallel signals and processes them for correction, converts them into raster data

(digital image data), and sends it to the scanner I/F of the PTC GA (IC36).

The raster data is arranged in words (16 bits) by the scanner I/F and transferred in DMA mode to the

PIX-SDRAM (IC9, IC13, IC15, IC19) where it is stored. During this period, this machine also communicates with the destination and determines the coding method for transmit data.

The raster data is transferred in DMA mode through the CODEC I/F-1 of the PTC GA to the CODEC

(IC1) installed on the FAX PWA. Then the CODEC converts the raster data into the coded data (MH,

MR, MMR or JBIG) to meet the destination.

The coded data is transferred in DMA mode through the CODEC I/F-1 to the system-SDRAM (IC32) where it is stored.

The coded data is transferred in DMA mode to the MODEM (IC4) installed on the FAX PWA. Then the

MODEM modulates the coded data into analog signals for the telephone line.

The analog signals are sent to the telephone line network through the NCU PWA. Then the data of the original is transmitted to the destination through the telephone line network.

The MODEM (IC4) installed on the FAX PWA receives analog signals from the telephone line through the NCU PWA. Then the MODEM decodes the received analog signals into coded data.

The coded data is transferred in DMA mode to the system-SDRAM (IC32) where it is stored.

The coded data is transferred in DMA mode through the CODEC I/F-1 of the PTC GA (IC36) to the

CODEC (IC1) installed on the FAX PWA. Then the CODEC converts the coded data into the raster data, and stores it in the SRAM (IC2,3).

The raster data is transferred in DMA mode through the CODEC I/F-1 to the PIX-SDRAM (IC9, IC13,

IC15, IC19) where it is stored.

The raster data is transferred in DMA mode through the CODEC I/F-1 to the CODEC. Then the

CODEC converts the raster data into the data coded in JBIG.

The JBIG data is transferred in DMA mode through the CODEC I/F-1 to the system-SDRAM where it is stored. Then the received data or JBIG data is stored in the SDRAM.

The stored JBIG data is transferred in DMA mode through the CODEC I/F-1 to the CODEC. Then the

CODEC converts the JBIG data into the raster data, and stores it in the SRAM (IC2,3).

The raster data is transferred in DMA mode through the CODEC I/F-1 to the PIX-SDRAM where it is stored.

The raster data is transferred in DMA mode to the PTC I/F of the PTC GA.

The PTC I/F serially transfers the raster data to the EET (IC68). The EET smoothes the raster data and transfers it to the LSU.

The LSU irradiates a laser beam to the drum to form a latent image on it according to the raster data.

Then toner adheres to the latent image on the drum. The toner is transferred to the paper, thereby printing the received data.

The line monitor circuit consists of the CML relay (NAD/SAD/TWD models: RLY2, ASD/AUD/CND/MJD models: RLY3), analog switch (NAD/SAD/TWD models: IC51, ASD/AUD/CND/MJD models: IC3), the I/O port GA-2 (IC6) and analog switches (IC4, IC5) on the Main PWA, and other peripheral devices. It switches the telephone line path with the analog switch and monitors the line status, pseudo-ring signal, and tone signal in facsimile transmission and reception with the speaker connected to CN47 on the Relay PWA. It also switches the analog switch to output a buzzer tone from the speaker.

The signal to be monitored is selected by switching the analog switch (IC4) according to the TONESEL signal and RING/TONE signal, which are output from the I/O port GA-2.

To monitor the line during transmission and reception, the I/O port GA-2 causes the CML1 signal to be

HIGH to switch the analog switch and connect the line to the MODEM side.

For line path switching control, refer to “4. 1 Line Path Switching Control Circuit” in this chapter.

The correspondence between the respective signal levels and monitoring signals is shown in the table below.
