PC DRUM CHARGING SECTION

• Both the Rotating Charge Brush and Precharge Film are used to negatively charge the
surface of the PC Drum.
• The Rotating Charge Brush applies charge directly to the PC Drum, which ensures that
the PC Drum is charged evenly and stably with a low voltage. It also helps reduce dra-
matically the amount of ozone produced in the copier as compared with corona dis-
charge systems.
• Prior to charging by the Rotating Charge Brush, the Precharge Film will perform prelimi-
nary charging of both ends of the PC Drum to enhance drum charging efficiency.
