GENERAL PRECAUTIONS REGARDING THE SERVICE FOR GD-1210/1250/1270/1160/1260

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

1) Transportation/Installation

- When transporting/installing the equipment, employ four persons and be sure to hold the posi-

tions as shown in the figure. The equipment is quite heavy and weighs approximately 120 kg (264.55 lb.), therefore pay full attention when handling it. (e-STUDIO2500c/3500c/3510c, e-STUDIO2330C/2820C/2830C/ 3520C/3530C/4520C, e-STUDIO2040C/2540C/3040C/3540C/4540C)

- When transporting/installing the equipment, employ two persons and be sure to hold the posi-

tions as shown in the figure. The equipment is quite heavy, and e-STUDIO205L/255/305 weighs approximately 57 kg (125.66lb.), and e-STUDIO355/455 weighs approximately 60 kg (132.28 lb.), therefore pay full attention when handling it. The equipment is quite heavy, and eSTUDIO206L/256/306 weighs approximately 58 kg (127.87 lb.), and e-STUDIO356/456 weighs approximately 61 kg (134.48 lb.), therefore pay full attention when handling it.

- When transporting/installing the equipment, employ four persons and be sure to move it by the

casters while lifting the stoppers. The equipment is quite heavy and weighs approximately 245 kg (540.12 lb), therefore pay full attention when handling it. (e-STUDIO5520C/6520C/6530C, eSTUDIO5540C/6540C/6550C)

- When transporting/installing the equipment, employ four persons and be sure to move it by the

casters while lifting the stoppers. The equipment is quite heavy and weighs approximately 202 kg (445.33 lb), therefore pay full attention when handling it. (e-STUDIO555/655/755/855, eSTUDIO556/656/756/856)

- Be sure not to hold the movable parts or units (e.g. the control panel, ADU or RADF) when trans-

porting the equipment.

- Be sure to use a dedicated outlet with AC 110 V / 13.2 A, 115 V or 127 V / 12 A, 220-240 V / 8 A

for its power source.

- The equipment must be grounded for safety.

11/12

- Select a suitable place for installation. Avoid excessive heat, high humidity, dust, vibration and

direct sunlight.

- Provide proper ventilation since the equipment 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”) on the rear.

- The equipment shall be installed near the socket outlet and shall be accessible.

- Be sure to fix and plug in the power cable securely after the installation so that no one trips over

it.

2) General Precautions at Service

- Be sure to turn the power OFF and unplug the power cable during service (except for the service

should be done with the power turned ON).

- Unplug the power cable and clean the area around the prongs of the plug and socket outlet once

a year or more. A fire may occur when dust lies on this area.

- When the parts are disassembled, reassembly is the reverse of disassembly unless otherwise

noted in this manual or other related documents. Be careful not to install small parts such as screws, washers, pins, E-rings, star washers in the wrong places.

- Basically, the equipment should not be operated with any parts removed or disassembled.

- The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband

since the ICs on it may be damaged due to static electricity.

Caution: Before using the wristband, unplug the power cable of the equipment and

make sure that there are no charged objects which are not insulated in the vicinity.

- Avoid expose to laser beam during service. This equipment uses a laser diode. Be sure not to

expose your eyes to the laser beam. Do not insert reflecting parts or tools such as a screwdriver on the laser beam path. Remove all reflecting metals such as watches, rings, etc. before starting service.

- Be sure not to touch high-temperature sections such as the exposure lamp, fuser unit, damp

heater and areas around them.

- Be sure not to touch high-voltage sections such as the chargers, transfer belt, 2nd transfer roller,

developer, high-voltage transformer, exposure lamp control inverter, inverter for the LCD backlight and power supply unit. Especially, the board of these components should not be touched since the electric charge may remain in the capacitors, etc. on them even after the power is turned OFF.

- Make sure that the equipment will not operate before touching potentially dangerous places (e.g.

rotating/operating sections such as gears, belts pulleys, fans and laser beam exit of the laser optical unit).

- Be careful when removing the covers since there might be the parts with very sharp edges

underneath.

- When servicing the equipment with the power turned ON, be sure not to touch live sections and

rotating/operating sections. Avoid exposing your eyes to laser beam.

- Use designated jigs and tools.

- Use recommended measuring instruments or equivalents.

- Return the equipment to the original state and check the operation when the service is finished.

- Be very careful to treat the touch panel gently and never hit it. Breaking the surface could cause

malfunctions.

3) Important Service Parts for Safety

- The breaker, door switch, fuse, thermostat, thermofuse, thermistor, IC-RAMs including lithium

batteries, etc. are particularly important for safety. Be sure to handle/install them properly. If these parts are short-circuited and their functions become ineffective, they may result in fatal accidents such as burnout. Do not allow a short-circuit or do not use the parts not recommended by Toshiba TEC Corporation.

4) Cautionary Labels

- During servicing, be sure to check the rating plate and cautionary labels such as “Unplug the

power cable during service”, “CAUTION. HOT”, “CAUTION. HIGH VOLTAGE”, “CAUTION. LASER BEAM”, etc. to see if there is any dirt on their surface and if they are properly stuck to the equipment.

5) Disposal of the Equipment, Supplies, Packing Materials, Used Batteries and IC-RAMs

- Regarding the recovery and disposal of the equipment, supplies, packing materials, used batter-

ies and IC-RAMs including lithium batteries, follow the relevant local regulations or rules.

6) When the option has been installed: When the EFI printer board has been installed, be sure to unplug the power cable before performing maintenance and inspection, otherwise troubles such as a communication error may occur.

Caution:

Dispose of used batteries and IC-RAMs including lithium batteries according to this manual.

Attention:

Se débarrasser de batteries et IC-RAMs usés y compris les batteries en lithium selon ce manuel.

1.3 Features

• A3/LD scanning Scans data across A3/LD width and transmits in A3/LD actual size.

• High-speed scanning Inputs an A4/LT-size transmitted document in about 0.7 seconds (A4/LT document transmitted widthwise).

• High-speed transmission

33.6 Kbps high speed modem Toshiba original high-speed communication modes EX and HS JBIG encoding system

• Dual Access

- FAX transmission

There are two types of FAX transmission: Page-by-page direct transmission and memory transmission that all pages are stored in the memory before being transmitted.

- FAX reception

Basically, all pages are input in the memory before being output. This reduces the time that the FAX communication occupies the machine, making Dual Access between the copying/faxing and printing operation possible.

Namely, the followings are possible:

- Memory input during the memory transmission

- Memory input during the memory reception

- Copying during the memory transmission

- Reception during the copying

- Reception during the memory output

- Reception during the list output

2. LSU-RELATED FUNCTIONS

2.1 Recording Mode

This machine offers various printing modes such as the selection of the applicable recording paper and the recording method, etc. to meet users’ needs. To take full advantage of these features, it is important to understand the concepts of the recording paper selection algorithm and printing algorithm as described in 2. 2.

2 - 1

LSU-RELATED FUNCTIONS

2.2 Recording Paper Selection Algorithm and Printing Algorithm

Before printing the received image, the preset settings are evaluated in the order of the following 1) and

2), and the printing is performed based on the result.

1) Recording paper selection algorithm

- Basically, the received image is printed on a sheet of paper of the same size as the original. However, if this size is not available, this algorithm determines on which size of recording paper the output should be made. (Actual Size Mode/Free Mode)

2) Printing algorithm

- Determines how the received image is to be printed. (Discard printing/Vertical reduction printing/ Regular size reduction printing/Split printing)

2.2.1 Recording paper selection algorithm

It is possible to distinguish the size of each received image (A3(LD)/B4(LG)/A4(LT)/B5/A5). Basically, recording paper of the same size as the original is used for printing. If recording paper of the size is not available, this algorithm selects paper of another size according to the setting in the Setting Mode.

1) Actual Size Mode (13-517: 0)

- Printing is performed when regular size reduction is not applied to the received image. In this mode, an A4/LT received image is printed on a B4 recording paper.

2) Free Mode (13-517: 1)

- Printing is performed on any available recording paper.

2.2.2 Printing algorithm

Recording paper has its effective printing area. Even if the size of the original paper and the recording paper are the same, the length of the original is normally longer. This means that the received image would be divided onto two sheets. To prevent this, the printing algorithm works as described in the following pages.

1) Discard printing

- Since the trailing edge area of the original is normally blank, this blank area is cut off to allow the image fit in one sheet in this mode. Image reduction is not performed.

- Maximum discarding amount: 0 mm: Discard not performed 10 mm: Corresponding to the inside the TTI 18 mm: Corresponding to the outside the TTI 1 22 mm: Corresponding to the outside the TTI 2 34 mm: A4 → LT conversion (TTI: Transmission Terminal Identifier)

When the discard function is ON (13–378:1): Actual size recording is performed with no vertical reduction nor division. The original image is recorded as it is. Namely, the data exceeding the effective printing area are discarded.

A

Area B is discarded.

A : Effective printing length B : Recording data length outside the effective printing area

Discard function Length of B (Discard parameter) Set value

OFF 0 mm 0

ON 10 mm 1

18 mm 2

22 mm 3

34 mm 4

Reference: These parameters should be set by the service technician (in the FAX Function Mode).

2) Vertical reduction printing (13–377: 0)

- The recording data length is reduced so that the image fits in the recording paper. The data can be reduced up to 90/75%, and the machine automatically selects the appropriate ratio.

2 - 4

3) Regular size reduction printing (13–517: 1)

- When the discard and vertical reduction printing cannot be applied to the received image, and any of the combinations A3 → B4, A3 → A4, B4 → A4, B4 → B5, B4 → A5, A4 → B5, A4 → A5, COMP → LT, COMP → ST, LD → COMP, LD → LG/LT, LD → ST, LT → ST, FOLIO → B5, FOLIO → A5 is satisfied, the regular size reduction printing is performed.

In case that the recording data length is within the effective printing length A, but the recording paper of the same size as the original’s or larger size is not available;

In case that the recording data length exceeds the effective printing length A, the vertical reduction printing is not applicable and larger size recording paper is not available; (In the following example, A4/LT original was sent but the recording length exceeds A4 size and the data do not fit in A4/LT even if the vertical reduction is performed. The reduction B4 → A4 or A3 → A4 is applied in this case.)

2.2.3 Setting for the split recording

1) Split recording onto A4/B5/A5/ST Set as to whether split recording onto the short length paper (A4/B5/A5/ST) is to be performed or not. When this function is disabled, split recording for A3/B4/A4 data onto A3/B4/A4/LG/LT recording paper is not performed.

2.3 Recording Paper and Function

The size of the recording paper on which the received image data are printed is determined according to the presence/absence of the recording paper and the above-mentioned function settings. Relation between the recording paper size and the function settings is described in this section.

2.4 Energy Saver Mode

The fuser unit, main power and power supply for the control panel can be shut off during a specified period of time such as night time that the machine is in the ready mode, using a weekly timer function of the equipment. When a FAX is received in the Energy Saver Mode, the fuser unit, main power and power supply for the control panel are automatically turned ON. Printing is then started when the machine reaches the specified temperature. The Energy Saver Mode is useful for hours in which the amount of communication is small and immediate printing is not necessary. The setting of the Energy Saver Mode and time (start time, end time) are made on the USER FUNCTIONS screen. (Default setting is made by the weekly-timer function of the equipment.)

The transmitting side sends a TCF signal and checks if any error occurs in image data before the image data communication to follow. When the receiving side detects an error in the TCF signal, it transmits an FTT signal to the transmitting side to request the retraining. When there is no error, the receiving side transmits a CFR signal. The TCF signal transmits all zeros for 1.5 seconds at the same modem speed as that for the training signal.

3.2.3 V.8/V.34 communication sequence

1) Outline

- V.8 is performed as a startup procedure to switch to V.34. V.8 can connect an existing facsimile machine to the equipment using a data modem or other V-series modems. The V.34 modem has a modem circuit previously recommended, allowing it to be also connected to the existing modems while they are upper compatible.

- New technologies such as the pre-emphasis technology *1 and the probing technology *2 are fully used. The pre-emphasis technology *1 not only speeds up the modulation, but also gains the S/N ratio. The probing technology examines the line characteristics and optimizes the modem for the line condition. Therefore, not only do these technologies speed up the transmission momentarily, but also the average speed of the process during the data transmission is increased.

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

- Following 14 types of the 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) *4 can be selected from 2,400, 3,000, 3,200 symbol/sec (mandatory), or 2,743, 2,800, 3,429 symbol/sec (option). The data rate can be set more accurately than the conventional modem.

3

*1: A signal is sent while raising the output level in the high-frequency band in which the noise

is relatively loud.

*2: Tone signal called “Probing Tone” is sent for the receiver to examine the line characteris-

tics of the line.

*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”. The “Symbol rate”,

“Modulating speed”, and “Baud rate” are the same thing. This machine cannot realize the speed of 2,743 symbol/sec.

Notes:

1. ECM is used in the V.34 procedure. If the setting for the ECM transmission/reception of the

user data is set to “Not performed”, the V.8 procedure is not performed and the procedure is not switched to V.34. V.17 or lower is selected in this case.

2. When the transmission/reception speed is set to 14.4 kbps or slower, the V.8 procedure is not

performed, and V.17 or lower is selected.

3. See “Late start (P3-20)” to move to the V. 8/V.34 procedure after starting with the V.21 proce-

dure.

4. After the V.34 procedure is started, the fallback for the V.34 procedure is performed.

However, the fallback for the V.17 mode or lower mode is not performed.

The available modulation mode is in formed. Each declares that it has V.34 capability. The procedure moves to V.34 in the phase 2.

After the information about the modem capability is exchanged, the receiver determines the modulation speed based on the result of reception of the probing signal which was sent by the transmitter.

To determine the image transmission speed, the transmitter sends a training signal.

The optimum image transmission speed is determined according to the training signal received.

3.3 FAX Automatic Switching

3.3.1 General functions

There are two types of setting for the FAX Auto-Switching Mode Selection: TEL Mode and FAX Mode.

3.3.2 TEL mode

This mode is selected to prioritize telephone communication when the frequency of the fax reception is low. When the TEL mode is selected, the automatic FAX reception function does not work. Therefore, when a calling signal comes from the exchange, the telephone ringer continues ringing until the operator picks up the handset. When the operator has learned that the caller is sending a FAX, he has to perform the manual reception operation.

3.3.3 FAX mode

This mode is selected when the telephone circuit is used only for FAX communication. When the FAX mode is selected and a calling signal comes from the exchange, the FAX reception operation starts automatically without ringing the telephone ringer.

In the FAX mode, a calling number can be set up to 15 calls in the self-diagnosis setting “CI detection counter” (13–372).

The line current detection circuit consists of the line current detection IC (IC2), ASIC (IC29 [IC26]) on the FAX board, and the other peripheral devices. It detects a dial tone and the hook status of the external telephone from the current flowing through the line.

When a dial tone is input from the telephone line, current flows through the line. The line current detection IC sends REVA1 and REVB1 to the ASIC as pulse signals. This allows a dial tone to be detected.

The CI detection circuit consists of the photocoupler (PC2), ASIC (IC29 [IC26]) on the FAX board and the other peripheral devices to detect a ring signal input from the telephone line.

The ASIC makes the CML1 signal become LOW to connect the CI detection circuit to the telephone line. When a ring signal is input from the telephone line, the photocoupler is repeatedly turned ON/OFF. This allows the CI1 signal to become a pulse signal and input to the ASIC on the FAX board, thereby detecting the ring signal.

The line monitor circuit consists of the CML relay (NA/TW: RLY2, EU/AU/AS/C: RLY3), analog switch (NA/TW: IC51, EU/AU/AS/C: IC3), the ASIC (IC29 [IC26]) and analog switches (IC3, IC9 [IC3, IC2]) on the FAX board, and other peripheral devices. It switches the telephone line path using the analog switch and monitors the line status and ringer signal in the FAX transmission and reception using the speaker connected to CN503 on the FAX board. 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 (IC3) according to SP-SEL signal and MON signal which are output from the ASIC.

To monitor the line during the transmission and reception, the ASIC makes the CML1 signal become HIGH to switch the analog switch and connect the line to the MODEM side. For the line path switching control, refer to  P. 4-5 "4.2.2 Line path switching control circuit".

The relation between the signal levels and monitoring signals is as follows.

Monitoring signal SP-SEL MON

LINE Monitor Line 1 LOW HIGH

Line 2 HIGH HIGH

Ringer/Alarm - LOW

The monitoring signal selected by IC3 is input to the analog switch (IC9 [IC2]) to select the output sound volume. The sound volume is selected by switching IC8 according to the VOLSEL0-2 signals output from the ASIC and selecting an input resistance for the monitoring signal.
