Transfer Belt Unit Contact Mechanism - Ricoh G147 Service Manual

6.12.3 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.
