Sensing system to allow side-by-side writing of photonic imagers to create wide and seamless xerographic images

摘要

An apparatus and method for stitching a at least two imagers together in a scanning system to produce accurate, wide and seamless images. The system includes a photoreceptor adapted to move in a process direction and at least two imagers for simultaneously forming a single scan line at a time, in a direction transverse to the process direction. The system also includes circuitry for stitching together the at least two imagers and for forming registration marks on the surface of the photoreceptor. Finally, the scanning system includes sensing circuitry for detecting displacements of successive registration marks and providing adjustment values to the stitching circuitry.
