Abstract: An apparatus (48) which advances a sheet (25) through a transfer zone (64) and into registration with information developed on a moving member (20). The sheet (25) is advanced to a position wherein a leading portion thereof is within the transfer zone (64) and a trailing portion thereof is immediately behind the transfer zone (64) relative to the forward direction of movement of the moving member (20). The leading portion of the sheet (25) is advanced through the transfer zone (64) at a first velocity and the trailing portion of the sheet (25) is advanced in a region immediately behind the transfer zone (64) at a second velocity, which is greater than the first velocity, so as to create a buckle (19) in the trailing portion of the sheet (25) in the region. The buckle (19) functions to eliminate relative velocity between the photoconductive belt (20) and any portion of sheet (25) within the transfer zone (64) so as to substantially eliminate slip between the sheet (25) and the photoconductive belt (20).

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.
