DRUM CHARGING10
The PC Drum Charge Corona has a Scorotron grid to deposit a negative DC charge
evenly across the surface of the PC Drum. The grid voltage (VG) applied to the grid
mesh is selected between -650V in the normal mode and -520V in the Photo mode
by the Constant-Voltage Circuit in High Voltage Unit HV1.
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 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.
