Transfer Belt Unit Contact Mechanism - Ricoh G035 Service Manual

2.9.4 TRANSFER BELT UNIT CONTACT MECHANISM

[D]
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 with the clutch rotates half of a
complete rotation. The contact lever, riding on the cam, is lifted up and the spring
[D] pushes the belt into contact with the drum.
The home position sensor [E] for the transfer belt contact 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 print jobs. The reasons for this
are as follows.
• To prevent the ID sensor pattern on the drum from being rubbed off by the
transfer belt.
• To prevent a change in the drum's characteristics because of the influence of
additives inside the rubber belt.
