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, harnesses 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, batteries, 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 and 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.

Vorsicht:

Entsorgung der gebrauchten Batterien und IC-RAMs (inclusive der Lithium-Batterie) nach diesem Handbuch.

2. SELF-DIAGNOSIS MODE

There are two types of the self-diagnosis mode for the FAX operation.

• Test mode (03), adjustment mode (05) and setting mode (08): Some items are added to the test mode (03), adjustment mode (05) and setting mode (08) of the self-diagnosis function when the optional FAX unit is installed.

• FAX function mode (13) and FAX clearing mode (1*): These two modes are newly added to the machine when the FAX unit is installed. Started up by turning ON the power while pressing the specified keys are being pressed.

The followings are the modes which are added to (or extend) the PPC self-diagnosis function.

Outputs the protocol trace list, dump list and function setting list

100% C Test Mode

100% F Test Mode

100% CL Test Mode

USER FUNCTIONS

To enter the desired mode, turn the power ON while pressing two digital keys designated to each mode (e.g. [0] and [5]) simultaneously.

Notes:

• To finish the self-diagnosis mode, make sure to turn the power OFF and then back ON. When the equipment is started in one of the self-diagnosis modes, the equipment is occupied by the mode until the power is turned OFF. In this case, the recovery processing for the FAX operation is not performed.

• Faxes received automatically during the self-diagnosis mode may not be printed out. Be sure to disconnect the modular code from the line connectors (LINE1, LINE2) of the equipment before starting the self-diagnosis mode. Also, be sure to finish the self-diagnosis mode by turning the power OFF and back ON before connecting the modular code.

• The trace list output mode can be used by operating from the Service UI screen for models in which Service UI is embedded. For details of Service UI, refer to the Service Manual of the MFP.
