2.2.6 Transfer Process

OVERVIEW
The image created on the OPC drum in the development process is transferred to the paper.
Transfer method is not the corona transfer but the roller transfer method by the transfer
roller.
By the roller transfer method, ozone generation resulting from corona discharge rarely
occurs, and the transferred image is little dislocated because the paper is always retained
between the drum and the transfer roller during printing.
A reversed bias is applied to the transfer roller during cleaning of the transfer roller prior to
printing.
The residual electric potential on the paper is removed by the discharge needle.
