Charge Corona ON/OFF control
• The Comb Electrode deposits a charge evenly across the surface of the Photo Conduc-
tor through a grid mesh.
• The corona unit has a comb electrode that discharges only toward the grid mesh. This
results in the amount of ozone produced being smaller than with the wire electrode.
• The grid voltage (Vg) applied to the Grid Mesh is controlled through the image stabiliza-
tion control.
