ABSTRACT:
In an electrostatographic reproduction apparatus capable of producing duplex copies, an intermediate transfer member is utilized for transferring a marking particle image from a member upon which such marking particle image is initially formed to the intermediate transfer member and thereafter from the intermediate transfer member to a receiver member. A fuser assembly, dispensing fuser oil to prevent offset of a marking particle image to the fuser assembly, is then utilized for fixing a transferred image on the receiver member. In order to prevent fuser oil contamination defects on copies produced by such reproduction apparatus, the intermediate transfer member and the member upon which a marking particle image is initially formed are rotated in timed relation to effect registered transfer of such marking particle image from the member to the intermediate transfer member during a print cycle. The starting point for marking particle image formation on the member upon which a marking particle image is initially formed, and thus the starting point for transfer to the intermediate transfer member for successive print cycles is adjusted, whereby the starting point for successive print cycles precesses along the surface of the intermediate transfer member.
