Abstract
A system and method for controlling a xerographic printer includes a subsystem for carrying out a function of the xerographic printer and affecting an electric field of a component. The system and method further include a bias transfer roll voltage operated in a constant current mode, and a voltage evaluator coupled to the biased transfer roll for measuring a change in a level of voltage of the bias transfer roll as the component affected by the subsystem passes through a nip region near the bias transfer roll for determining operability of the subsystem.
