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.
