8. TRANSFER ROLLER UNIT
8.1 TRANSFER BELT/ROLLER HEATER CONTROL
The resistance of the transfer roller [A] changes with the environment. It is
especially at low temperatures.
The transfer roller thermoswitch [B] detects the temperature around the
transfer roller. To keep the resistance of the transfer roller at a constant
level, when the detected temperature is 20
°
C or less, the transfer belt/roller
heaters [C] turn on until the temperature rises above 20
°
C.
The heaters are not turned on/off by the main switch. The heaters operate
whenever the copier power cord is plugged in.
