Transfer and Separation

Pick-off Pawl

Discharge Plate

The machine uses a transfer roller [4], which touches the surface of the OPC drum [1]. The high voltage supply

board supplies a positive current to the transfer roller, which attracts the toner from the drum onto the paper. The

current depends on the paper width, paper type, and paper feed tray.

The curvature of the drum and the discharge plate [3] help the paper to separate from the drum. The high voltage

supply board also supplies a negative dc voltage to the discharge plate. The drum/waste toner motor drives the

transfer roller through the OPC drum [1].
