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.

Abstract: A method of providing machine usage data to a computer for a given user by setting the machine for transmission of the machine usage data to the computer and transmitting the machine usage data to the computer for various levels of usage. The computer converts the machine usage data into a format compatible for the given user, for example, converting to a generic ASCII type file format or to an MS Excel format.
