Paper Transfer and Discharge
Transfer Roller
The transfer roller [A] is always pressed against the image transfer belt by pressure from a spring. The
transfer roller moves toner images [B] from the transfer belt to the paper. When a sheet of paper [C] goes
between the transfer roller and the transfer belt, the transfer roller turns with the paper.
Paper Transfer Bias
The high voltage power supply (HVPS) supplies electricity to the transfer roller. The transfer roller is positively
charged. The right end of the transfer unit is attached to the terminal from the HVPS when you close the
front cover.
Discharge Plate
The transfer unit has a discharge plate [D] above the transfer roller. The discharge plate removes charge
that was applied to the paper during paper transfer. This helps paper move away from the transfer roller.
