2.2.4  Transfer Process
†
Overview
„
The image created on the OPC drum in the development process is transferred 
to the paper.
„
Transfer is performed by the roller transfer method using the transfer roller.
„
By the roller transfer method, ozone is generated rarely and the transferred 
image is little dislocated since the paper passes between the drum and the 
transfer roller all through during printing.
„
The transfer roller is cleaned by applying a reversed bias to the transfer roller.
„
Cleaning of the transfer roller is carried out at start up of the printer, at 
printing start, at printing end and at starting after clearing a paper jam.
„
The residual electric potential on the paper is removed by the discharge 
needle.
