Abstract
An imaging system for forming multiple image exposure frames on a photoconductive member moving in a process direction including a raster output scanner forming a plurality of scanlines in a transverse direction across the width of the member by reflecting modulated beams from a plurality of facets of a rotating polygon. Hall effect magnetic sensors mounted with respect to a motor driving the polygon provide a first speed control of the polygon with the laser in a not ready or an off state and start of scan signals detecting the beginning of a scan line provide a second speed control of the polygon with the laser in an on or ready state. Circuitry or control code responds to the SOS signals and the magnetic sensors to dynamically switch between the first speed control and the second speed control.
