12.2 Operation

• The surface of the drum is deposited with charge through corona discharge from the
drum charge corona.
• The grid mesh interposed between the corona wire and the drum ensures that a uniform
charge is deposited across the entire surface of the drum.
• 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.
