2.5.3 CONTACT AND SEPARATION
The transfer roller contact/separation idler [A] and the transfer roller clutch [B]
transfer drive from the main motor to the cam [C].
The transfer clutch (a 1/2-turn clutch) controls the contact between the transfer
roller and the transfer belt. The transfer roller position sensor [D] detects the
contact and separation positions. The transfer roller is driven by contact with the
transfer belt.
If the transfer roller contacts the transfer belt (i.e., the transfer roller position sensor
is on) just after the main switch is turned on or just after the door safety switch is
turned on (i.e., the front cover is closed), the machine assumes a paper jam has
occurred. The main motor is driven to engage and disengage the transfer roller
clutch, separating the transfer roller from the transfer belt (until the transfer roller
position sensor is turned off).
