GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND SERVICE FOR THE COPIER 2460

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

1. Transportation/Installation

• 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 83 kg (183 lb), therefore pay full attention when handling it.

4 portions

2. Installation

• Be sure to use a dedicated outlet with AC 115V/15A (220V, 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.

• Secure the lifting handles with the fixing plates and screws after the installation is finished.

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, 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.

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 or 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 packing materials, 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: Be sure to turn off the copier before attaching the wrist-band.

Always remove the wrist-band before applying power.
