Abstract

A method of synchronizing the arrival of copy sheets at a photoreceptor in an image processing having a copy sheet path having a plurality of segments coupled at given transfer zones, a plurality of copy sheet drives, an image transfer station, a photoreceptor and a controller. The controller directs the image processing apparatus by tracking the movement of copy sheets at the image transfer station in relation to the movement of the photoreceptor, monitoring the movement of copy sheets at the transfer zones, determining the need to adjust the spacing of copy sheets along the plurality of segments of the copy sheet path, and suitably activating selected copy sheet drives.
