Theory of Operation
Charging
The drum surface is charged with negative electricity by discharging of the bias
charge roller (BCR) while rotating at a constant speed. This process is performed in
parallel for Cyan, Magenta, Yellow, and Black colors.
The BCR is kept in contact with the drum and rotates following the rotations of the
drum. The BCR is a conductive roller, which receives negative voltage from the
High-Voltage Power Supply (HVPS) and discharges a negative Direct Current (DC)
voltage.
The drum surface is uniformly and negatively charged with DC bias voltage. The
drum surface is a photoreceptor (an insulator in a dark area and a conductor when
receiving light), and the drum inside is conductive.
The cleaning roller is a sponge that contacts the BCR to catch the toner.
