GENERAL PRECAUTIONS REGARDING THE INSTALLATION

AND SERVICE FOR THE COPIER AR-651/810

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 use caution

when handling it.

• Be sure to use a dedicated line with AC 115V or 120V/20A (220V, 230V, 240V/10A) or more for its

power source.

• The copier must be properly 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, direct sunlight and areas where the tempera-

ture may change rapidly such as in direct line with a heating or cooling duct.

• 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.

• The power source must be installed near the copier and should be easily accessible in proper

safety.

Do not use an extension cord to provide power.

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 the high-voltage sections such as the chargers, high-voltage transformer,

exposure lamp control inverter, inverter for the LCD backlight and power supply unit. These com-

ponents and their PWB's should not be touched even if the power has been turned off since an

electirc charge may remain in their condensers, etc.

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

• Be careful when removing the covers since there might be parts with very sharp edges under-

neath.

• When servicing the machines with the main switch turned on, be sure not to touch live sections

and rotating/operating sections. Avoid exposure to the laser's radiation.

• Use suitable measuring instruments and tools with the proper specifications.

• Avoid exposure to the laser's radiation during servicing.

- Avoid direct exposure to the laser 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.
