    Abstract: A printing machine (100) is arranged to detect an arcing event. An arcing detection signal (231) based on the arcing event is formed. The arcing detection signal includes an arcing detection signal frequency and an arcing detection signal amplitude. The arcing detection signal frequency value and the arcing detection signal amplitude value are used to detect the occurrence of an arcing event. Once an arcing event is detected, an arcing level corresponding to the severity of the arcing event is determined. At least one arcing remedy based on the arcing level then is performed. The arcing remedy comprises any of logging the arcing event, generating a maintenance message, performing a maintenance procedure, informing a maintenance person, dispatching a maintenance person and powering-down the printing machine.

    Abstract: An apparatus and method for maintaining a constant voltage potential on a photoconductive member within an electrophotographic printing system comprises and utilizes, respectively, a charging device, a voltage monitor and a controller. The charging device produces a voltage potential on a photoconductive member within the electrophotographic printing system. The voltage monitor measures the voltage on the photoconductive member and generates a voltage measured signal. The controller, responsive to the voltage measure signal, stores a target voltage value and computes the difference of the measured voltage signal and the target voltage value to obtain a voltage error for a prior print job. The controller computes a predicted control signal for the corresponding cycle of the next successive print job as a function of the voltage error and regulates the charging device for the corresponding cycle of the next successive print job as a function of the predicted control signal.
