Patent 7995089 was granted and assigned to Xerox on August, 2011 by the United States Patent and Trademark Office.
A technique for minimizing motor polygon assembly output reflectivity using real time facet reflectivity measurements and mapping. An automatic power control sensor manages laser beams produced by the laser source associated with the system during overscan periods ‘outside’ of defined printing time. Errors are then recorded internal to the raster output scanner to minimize overall setup in the image output terminal.
