Transfer and separation sections

The transfer and separation sections consists of the transfer roller, separation electrode and drum separation claws.
A high voltage generated by the high voltage PWB (HVTPWB) is applied to the transfer roller for transfer charging.
Paper after transfer is separated from the drum by applying separation bias that is output from the high voltage PWB
(HVTPWB) to the separation electrode.
