3.6.1 Charging
The exposure drum needs to be evenly electrified to coat toner beautifully on the exposure
drum. Ions are produced by supplying high-voltage power to the corona wire. The flow of the
ion charge is controlled by the constant voltage of the grid approximately 700 V and electrified
the exposure drum surface evenly.
