Transfer Belt Unit Contact Mechanism
The belt contact and release mechanism consists of the belt contact clutch [A], cam [B], and contact lever
[C]. The belt contact clutch turns on and the cam attached to the clutch rotates half a complete rotation.
The contact lever, riding on the cam, is lifted up and the springs [D] push the belt into contact with the drum.
The transfer belt position sensor [E] detects the home position of the cam (this is when the belt is away from
the drum). The belt must be released from the drum between copy jobs in order to prevent the ID sensor
pattern from being rubbed off and to prevent contamination of the drum from the surface of the belt.
