•
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.
