ABSTRACT:
A recording apparatus of the type having an endless movable belt on which an image is formed and transferred in registration to a transfer surface. Registration between the transfer roller and the printhead is provided in part by a sprocket engaging the belt through a series of perforation along an edge of the belt. Prolonged integrity and increased load carrying capacity of the perforations are obtained by having a sprocket drive that drives the belt through its perforations in cooperation with a friction drive for driving the belt.
