Theory of Operation
2nd BTR Contact Retract Motor (PL14.4.10)
The 2nd BTR Contact Retract Motor drives the shaft with the attached Cam that
operates in tandem with the 2nd BTR. This motor operates when transferring the
toner image from the belt onto the paper. By rotating the Cam, the 2nd BTR
contacts the paper that is passing on the belt.
POB Sensor (PL14.4.16)
The POB Sensor detects the paper with transferred image that has passed the belt
during the Secondary Transfer process.
Note
