ABSTRACT:
A scanner adapted to selectively discharge a charged photosensitive surface emits a plurality of light beams, with the plurality of light beams impinging on the charged photosensitive surface forming a composite light spot to discharge the charge thereon. The intensity of at least one of the plurality of light beams may be varied to adjust the position of the composite spot centroid on the charged photosensitive surface.
