Gp 11 Drum Charge - Xerox FaxCentre F116 Service Manual

GP 11 Drum Charge

Overview
• The Drum is charged with static electricity before laser exposure.
• The BCR and the Pre-charge Film are used for the charging method.
• The BCR and Pre-charge Film charging generate little ozone in the machine. Because the
charge is directly applied to the Drum, the Drum can be charged by low voltage. At the same
time, the Drum can be charged stably and evenly
• The Pre-charge Film supplies the charge to the Drum before being charged by the BCR to
improve the charging efficiency.
• The BCR is turned by the drive of the Main Drive Motor (M1) via a gear.
• The electric potential on the surface of the charged Drum is approximately-800 V.
