6.15.3 TRANSFER BELT UNIT LIFT
The transfer belt lift solenoid [A] (a magnetic latching solenoid 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 when the solenoid turns on.
The support spring [E] 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 VD, VH, 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.
