Toshiba FC-22 User Manual

GENERAL PRECA UTIONS REGARDING THE INSTALLATION AND SERVICE FOR THE COPIER FC-22

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

1. Transportation/Installation

• When transporting/installing the copier, move it by the casters while lifting the stoppers. The copier is quite heavy and weighs approximately 200 kg (441 lb), therefore pay full attention when handling it.

• Be sure to use a dedicated outlet with AC 115V or 120V/20A (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.

2. 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, the transfer belt and the highvoltage transformer.

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

• Avoid exposure to laser radiation during servicing.

− Avoid direct exposure to the 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.

3. 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.

4. 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.

5. Disposition of Consumable Parts/Packing Materials

• Regarding the recovery and disposal of the copier, supplies, consumable par ts and packing materials, it is recommended to follow the relevant local regulations or rules.

6. 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, star washers in the wrong places.

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

8. Precautions Against Static Electricity

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

band, because the ICs on it may become damaged due to static electricity.

Caution: Before using the wristband, pull out the power cord plug of the copier and make

sure that there are no uninsulated charged objects in the vicinity.

Caution : Dispose of used RAM-ICs (including lithium battery)

according to the manufacturer’s instr uctions.

Vorsicht : Entsorgung des gebrauchten RAM-ICs (inklusive

der Lithium-Batterie) nach Angaben des Herstellers.
