Title: Transfer Di-chorotron (Dicor) cover with constant paper current density

Abstract: A sliding cover of a Di-chorotron includes an electrode connected to an external circuit that simulates the impedance of media on a photoreceptor to maintain constant current density through media on the photoreceptor while blocking transfer current from passing to uncovered portions of the photoreceptor, thus reducing or eliminating paper edge ghosting effects in a xerographic machine's output.
