PHOTOCONDUCTOR UNIT (PCU)
G071 6-22 SM
Contact Mechanism
During standby mode, the cleaning unit is away from the transfer belt.
When the toner images are being transferred from the OPC belt to the transfer belt,
this mechanism holds the transfer belt cleaning unit away from the belt.
When the solenoid [A] activates, it transmits power from the fusing unit motor [B] to
the gear and the cam [C]. The cam moves the bias brush roller into contact with the
transfer belt.
[A]: Transfer belt cleaning
contact solenoid
[B]: Fusing unit motor
[C]: Cam
The transfer belt cleaning unit [D] has a lever [E] on its rear side. When the lever
rests on the high point of the cam [F], the cleaning unit is away from the transfer
belt; when the lever rests on the low point, the cleaning unit contacts the transfer
belt.
[D]: Transfer belt cleaning unit
[E]: Lever
[F]: Cam
[G]: Gear
[H]: Transfer belt cleaning contact
solenoid
[I]: Half-turn clutch
The transfer belt cleaning contact solenoid [H] operates a half-turn clutch [I] to
control the contact mechanism.
