AUTOMATIC DUPLEXING UNIT

MD-5002

GENERAL PRECAUTIONS REGARDINGTHE INSTALLATION

AND SERVICE FOR THE COPIER 2060, 2860/70 AND THE AU-

TOMATIC DUPLEXING UNIT MD-5002

1. Transportation/Installation

• When transporting/installing the copier, use two persons and be sure to use the positions as indi-

cated below.

The copier is fairly heavy and weighs approximately 73 kg (161 lb), therefore pay full attention

when handling it. (2870: 84 kg)

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.

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

such as the lamp terminal, etc.

• 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. Notice Labels

• Be sure to check the rating plate and the cautionary labels such as “Unplug the power cord during

service”, “Hot area” etc. to see if there is any dirt on their surface or if they are properly stuck to the

copier during servicing.

6. Disposition of Consumable Parts/Packing Materials

• Regarding the recovery and disposal of the copier, supplies, consumable parts and packing mate-

rials, 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.
