ABSTRACT:
An electrostatic marking system has a cleaning station and a cleaning blade wherein the cleaning blade is adjustable depending upon data of cleaning station temperature, humidity, and a contaminant film on a photoreceptor P/R surface. A sensor or sensors measures this data including the thickness of the film together with temperature and humidity in the cleaning station. This data is conveyed by the sensors to a controller which has software equating this data with an angle at which the cleaning blade contacts the P/R surface. This angle is calculated to give maximum cleaning of the P/R surface with minimum abrading of this P/R surface.
