GENERAL PRECAUTIONS REGARDING THE SERVICE FOR e-STUDIO163/203

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

1) Transportation/Installation

- When transporting/installing the equipment, remove the drawer, employ two persons and be sure

to hold the positions as shown in the figure. The equipment is quite heavy and weighs approximately 32 kg (70.55 lb), therefore pay full attention when handling it.

- Be sure not to hold the movable parts or units when transporting 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 or 240

V / 8 A for its power source.

- The equipment must be grounded for safety.

- 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 easily 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, developer, high-voltage trans-

former 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.

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.

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.

Notes:

1. Test printing is set by default to continue until the [CLEAR] button is pressed, or an error occurs. Note that printing may therefore continue until the paper set in the specified drawer completely runs out.

2. When an error occurs, it is indicated on the panel, but the recovery operation is not performed. Turn OFF the power and then back ON to clear the error.

3. During test printing, all button operations are disabled when the Message lamps on the control panel light.
