Patent ID: 8576458

Claim:
A raster output scanner (ROS) for generating an image on a portion of a photoreceptor traveling along a process path past the ROS, comprising: at least one light source operative to generate a light output; a driver operative to selectively actuate the at least one light source according to image data to produce at least one modulated light output; a motor polygon assembly comprising a rotating polygon with a plurality of reflective facets individually operative to scan the at least one modulated light output of the at least one light source directly or indirectly to a photoreceptor of a printing system along a fast scan direction to generate an image on at least a portion of the photoreceptor according to the image data; and a controller operatively coupled with the driver to cause the driver to selectively vary an output level of the at least one modulated light output provided by the at least one light source during scanning by a given reflective facet of the rotating polygon to mitigate banding according to a given one of a plurality of banding correction profiles that corresponds to the given reflective facet.
