PC DRUM CHARGE CORONA

• The PC Drum Charge Corona generates corona emission to deposit a charge evenly
across the surface of the PC Drum through a grid mesh.
• It has a comb electrode, which ensures that a charge is concentrated on the grid mesh,
thus reducing the amount of ozone produced.
• The grid voltage applied to the grid mesh is generated by the Constant-Voltage Circuit in
High Voltage Unit 1.
• The constant voltage of High Voltage Unit 1 is determined through image stabilization
control.
