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 cir-
cuitry within the High Voltage Unit. It is varied through image stabilization control.
• To restrict ozone production, the copier uses a PC Drum Charge Corona with a comb
electrode.
