6. DRUM CHARGE
(1) Overview
• The PC Drum is charged with static electricity before laser exposure.
• The Drum Charge Brush and the Pre-charge Film are used for charging.
• Since the Drum Charge Brush and the Pre-charge Film directly deposit charge on the PC
Drum, they produce little ozone. Further the charging voltage is low and the deposited
charge is even and stable across the surface of the PC Drum.
• The Pre-charge Film supplies a preliminary charge to the PC Drum prior to charging by
the Drum Charge Brush, thereby increasing charging efficiency.
