1.1 INSTALLATION REQUIREMENTS

The installation location should be carefully chosen because environmental

conditions greatly affect the performance of a copier.

1. Environments to Avoid

•Avoid any area exposed to direct sunlight or strong light (Illumination must be

less than 1500 Lux).

•Avoid any area exposed to extremes of temperature and humidity (standard

condition: 10°C ~ 30°C, 15% ~ 90%).

•Avoid any area exposed to heated air from a heater.

•Avoid any area where temperature suddenly changes from low to high or vice

versa.

•Avoid placing the copier in an area filled with dust, and subjected to frequent

strong vibration.

•Avoid narrow space (10 m3).

2. Access to Copier

Place the copier near a power source, providing clearance as shown. The copier

must be level within 5 mm both front to rear and left to right.

3. Power Connection

•Input voltage level:

220 V/50 Hz, more than 10 A

•Avoid connecting the power cord

to a socket that already has

power cords attached

•Permissible voltage fluctuation:

220 V (±10%)

•Avoid using a power cord

extension. If you must use one,

make sure that it can carry 250

V, 10 A and that it is less than 5

m long.

4. Earth Connection

•Be sure to ground the machine properly.
