2.4.6 Drum Charging

A scorotron charger system generates a negative DC corona discharge onto the PC Drum surface. The
grid mesh ensures uniform charging.
The grid voltage (Vg) applied to the grid mesh is controlled by the constant voltage circuitry within the
High Voltage Unit. It is varied through image stabilization control.
To restrict ozone production, the machine uses a PC Drum Charge Corona with a comb electrode.
