Drum Charge
Overview
The drum charge roller [A] remains in contact with the drum, producing a charge of –900 V on the drum
surface.
The high voltage supply board [B] supplies a negative charge to the charge roller via wire [C] and spring
[D]. The default base (uncorrected) charge is –1650V. You can adjust this base charge using SP20011.
The actual charge is corrected in accordance with the ambient environment, as described in the next section.
