Abstract

A multiple pitch color registration system is disclosed for registering two images that are not precisely placed on a photoreceptor in an electrophotographic printing machine. The registration system is able to run asynchronously for a period of time and then to resynchronize in two different pitch modes. A two roll transfer loop for transferring the plurality of colors is phase locked to the photoreceptor position so that the two roll transfer loop follows the photoreceptor motion errors for maintaining accurate registration.
