11.2 Operation
11.2.1 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

10.3 Operation
10.3.1 Photo conductor drive mechanism
A. Photo conductor drive
• The photo conductor is driven by the Main motor (M1).
10.3.2 Photo conductor cleaning mechanism
• The cleaning blade is pressed up against the surface of the photo conductor, scraping
residual toner off the surface.
• The toner scraped off the surface of the photo conductor is collected in the drum car-
tridge.
