CHAPTER 4 IMAGE FORMATION SYSTEM

IV. TRANSFER

A.

Outline

The transfer block consists of the intermediate transfer drum, secondary pre-transfer
charging assembly, secondary transfer belt, separation static eliminator, and ITD clean-
ing roller, and serves to transfer the toner image from the photosensitive drum to paper
and to remove residual toner.
The intermediate transfer drum is rotated by the drum motor (M2), and the secondary
transfer belt is rotated by the main motor (M4). When the secondary transfer belt clutch
(CL4) turns on, the secondary transfer belt is forced against the intermediate transfer
drum. When the ITD cleaning roller solenoid (SL1) turns on, on the other hand, the ITD
cleaning roller is forced against the intermediate transfer drum.
