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

    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.
