2.3 Technical Explanation of Print Process
2.3.1 Charging
In charging process, BCR (Bias Charge Roll) applies a uniform negative potential to
the drum which rotates at a fixed speed. This process is performed simultaneously for
each of the yellow, magenta, cyan and black colors.
BCR is a conductive roller and keeps contact with the drum to move together with
it. HVPS supplies discharge voltages to the BCR, and then the BCR discharges
negative DC voltage.
Drum surface is uniformly charged to a negative potential with DC bias voltage.
The Drum surface is made of conductive material coated with a photosensitive
material that becomes insulating in darkness and becomes conductive when it is
subjected to light.
Cleaning Roll contacts the BCR and attracts toner.
