[ 1 ] Drum Charge Section
The drum is charged with static electricity before laser exposure.
The rotating charge brush and the pre-charge film are used for the charging method.
The rotating brush charging 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 rotating
charge brush to improve the charging efficiency. The rotating charge brush is turned by the drive of the
RX motor via a gear.
