GP 12 Drum Charge
Overview
• The 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 drum,
they produce little ozone. Further the charging voltage is low and the deposited charge is
even and stable across the surface of the drum.
• The pre-charge film supplies a preliminary charge to the drum prior to charging by the drum
charge brush, thereby increasing charging efficiency.
