Abstract

Systems and a method for image forming systems to skip over the non-printing photoreceptor area in order to not skip a label position on a continuous print web medium. A vacuum assembly is coupled to a controller that controls different vacuum pressures at each vacuum roller therein. The vacuum rollers provide drag and drive forces to skip a seam of the photoreceptor and a residual length based on the number and size of images on the photoreceptor.
