2.9.2 TRANSFER BELT UNIT LIFT
The transfer belt lift solenoid [A] inside the transfer belt unit turns on to raise the
transfer belt into contact with the drum. The front lever [B] and the rear lever [C] are
connected to the solenoid by links [D], and they push up the stays [E] when the
solenoid turns on.
The support spring [F] helps the solenoid to raise the transfer belt.
The solenoid turns off after the copy job is finished.
The transfer belt must be released from the drum for the following reasons:
1. To prevent the ID sensor pattern on the drum from being rubbed off by the transfer
belt, because the transfer belt is located between the development unit and the ID
sensor.
2. To decrease the load on the bias roller cleaning blade, it is better to prevent toner
on non-image areas (for example V D , V H , ID sensor patterns developed during
process control data initial setting) from being transferred onto the transfer belt.
3. To prevent drum characteristics from being changed by remaining in contact with
the rubber belt.
