Canon np6330 서비스 매뉴얼

The upper roller, lower roller, and delivery roller 1 are driven by the main motor (M1),

and the delivery roller 2 is driven by the delivery motor (M6).

The copier’s upper roller is heated by two fixing heaters (H1 : 750 W (220 / 240 V) /

700 W (120 V) ; H2 : 640 W (220 / 240 V) / 600 W (120 V)), and its surface temperature
is monitored by a thermistor (TH1).

The DC controller turns on and off the fixing heater drive command (MHRD, SHRD)

based on the fixing temperature signal (TH1, analog) from the thermistor.

The control temperature and the area of heating during copying are varied according

to the following:

• Copy paper size (width)
• Number of copies (continuous copying)
