Image Transfer / Paper Separation
Image Transfer
After passing through the registration unit, the paper passes between the OPC drum and the transfer roller. During this
time, the toner on the OPC drum surface is transferred to the paper by the positive electric charge on the transfer roller.
The voltage is applied to the transfer roller from the PSU via receptacles, electrode terminals, transfer roller spring (at
the front) and bearings (conductive resin).
To minimize fluctuations caused by factors such as the environment and paper types, constant current control is
performed.
