Charge corona control

A. Charging grid
• The photo conductor is charged through corona discharge from the photo conductor
charge corona.
• The photo conductor is charged via a grid mesh, which ensures that an even charge is
applied to the entire surface of the photo conductor.
• The photo conductor charge corona of a comb electrode type discharges only to the grid
mesh side, involving a smaller amount of ozone produced as compared with the wire
electrode.
• Charge corona output rating: -500uA
