Abstract
An electrophotographic printing machine utilizes an improved image registration system that forms and senses image registration indicia to control a subsequent transfer of a visible image. A first transfer station transfers registration indicia, previously formed on a first photoconductive member and transferred therefrom, onto a receiving member. A sensor monitors the registration indicia on the receiving member and generates a control signal indicative thereof. A second transfer station, responsive to the control signal, transfers a visible image, previously formed on a second photoconductive member and transferred therefrom, to the receiving member.
