Service Manual for OF5800
Chapter 2 Machine Operations
The PC Drum is charged with static electricity before laser exposure. The Rotating Charge Brush and
the Precharge-film are used to charge the surface of the drum.
The rotating brush and the Precharge-film charging generate ozone in the printer. Because the charge
is placed directly on the PC Drum, it can be charged by a low voltage. At the same time, the PC Drum
can be evenly charged.
The Precharge-film supplies the charge to the Rotating Charge Brush to improve the charging
efficiency.
The Rotating Charge Brush is turned by the Main Motor.
