ABSTRACT:
An electrophotographic copying system is disclosed wherein the DC charging and DC transfer corotrons are powered with an unfiltered full wave rectified voltage derived from a 110 volt, 60 hertz line source. The DC corotrons are regulated along with AC corotrons used for detack and erase operations. The regulation is achieved by a feedback loop coupled to only one of the corotrons.
