DRUM CHARGING
The PC Drum Charge Corona above the Imaging Unit deposits a negative
DC charge evenly across the surface of the PC Drum.
The Corona Unit has a Comb Electrode which minimizes the amount of
ozone produced. The conventional wire type corona unit produces a large
amount of ozone due to corona discharge in radial directions. The comb
electrode type, on the other hand, discharges corona only toward the Grid
Mesh, meaning a reduced amount of ozone is produced.
The Comb Electrode can be cleaned by the user who pulls out to the front
the shaft on which a Cleaning Rollar is mounted.
