Abstract:
1. An electrostatic marking system comprising a cleaning station, said cleaning station comprising: a photoreceptor P/R surface, at least one sensor and at least one controller, at least one cleaning blade in a blade cleaning angle contact with said photoreceptor surface, said photoreceptor surface having a contaminant film thereon, said sensor configured to measure data (measured data) of said cleaning station including a thickness of said contaminant film or data that can be used to determine contaminant film thickness or the rate of contaminant film growth, said sensor in communication with said controller and configured to send said data to said controller, said controller comprising predetermined algorithms equating contact angle of said cleaning blade against said measured data, said controller configured to adjust and set said blade cleaning angle and a cleaning blade adjuster in accordance with said data to provide substantially maximum P/R film cleaning together with minimum abrading of said P/R.
