6. IMAGE TRANSFER AND PAPER

SEPARATION

6.1 OVERVIEW

Instead of using a transfer wire and a transfer belt, this machine uses a

transfer roller [A], which touches the drum surface.

The high voltage supply board [B] supplies a positive current (approximately

+15 µA) to the transfer roller. The roller has a high electrical resistance, so it

can hold a high positive electrical potential to attract toner from the drum onto

the paper.

There is a discharge brush [C] after the transfer roller. The curvature of the

drum and the discharge brush helps the paper to drop away from the drum.

The transport fan [D] under the transport guide plate helps to transport the

paper from the transfer area to the fusing unit.
