Abstract
Systems and methods for reducing the degradation of image quality due to banding in an image processing system by detection of both integrated intensity and peak intensity of a laser beam reflected from the polygon mirror facet(s) of a motor polygon assembly. A banding detector is adapted to enable measurement of peak intensity and integrated intensity of the laser beam(s) reflected from the polygon mirror facet(s). Polygon facet induced banding can be determined from the measurements and can be used for sorting/manufacturing raster output scanners and/or compensating for the induced banding.
