Abstract

A corotron voltage control method for optimization of transfer and detack corotron performance in electrophotographic printing and copy machines is disclosed. A paper substance sensor determines the basis weight of paper copy sheets as they leave a paper feeder. The transfer and detack corotron settings are then adjusted to optimal settings based upon paper weight according to look up table valves before the sheet arrives at the photoreceptor. The method as summarized in the figure flow chart provides for improved copy quality, increased photoreceptor life, and reduced photoreceptor misstrips.
