Abstract
A method for monitoring filming levels on a photoreceptor surface of a printing machine includes the use of an enhanced toner area coverage sensor to measure level of filming of substantially the entire photoreceptor surface, the sensor being located at a point downstream from a cleaning station of the printing machine. When the measurement indicates that the filming is unacceptably high on a portion of the photoreceptor surface, corrective action is implemented, for example filming removal. The sensor is preferably mounted in a manner such that it may be moved over substantially the entire surface of the photoreceptor. Also, an electrostatic voltmeter is preferably mounted along with the sensor in order to monitor the charging of the photoreceptor surface.
