ABSTRACT:
A system for compensating for motion errors that degrade image quality by modifying the modulation of a scanning beam across a photosensitive surface in response to changes in speed of the photosensitive surface by use of a shaft encoder mounted adjacent to the photosensitive surface to determine the speed of the photosensitive surface, a comparator electrically connected to the sensor for determining the change of speed of the photosensitive surface in relation to a standard speed, a converter connected to the comparator and responsive to the change in speed to provide a signal representing an image quality factor, and for altering the modulation of the beam of the scanning system in relation to the speed of the photosensitive surface.
