ABSTRACT:
A power supply system for transfer rollers associated with electrostatographic marking engines. The power supply system includes a power source having a fixed and constant output parameter, such as current or voltage. Additional resistance is connected to the output of the power source to provide the most desirable bias level on the transfer roller under actual operting and material conditions. With a constant current source, a resistance is connected in parallel with the load impedance of the roller system. With a constant voltage source, the resistance is connected in series between the voltage source and the roller system.
