Abstract
The present invention is directed to a precession scanning system wherein a platen moving in a first direction is scanned by a scan illumination assembly and lens moving in the opposite direction. The projected image is precessed onto a moving photoreceptor belt in a direction opposite the belt motion. The velocity relationship between platen, lens, scan illumination assembly and photoreceptor, as well as scan distance, are governed by a unique set of relationships.
