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.
•Do not connect the grounding wire to a gas pipe.
