ABSTRACT:
A system, including a specially-designed optical element, facilitates extremely precise and accurate registration of a light beam on a photoreceptor. The optical element includes a redirecting cylinder lens, having a longitudinal axis oriented obliquely relative to the scan path of the light beam to redirect the light beam. The redirected light beam interacts with an aperture in the photoreceptor to provide an accurate measuring device for the exact position of the aperture with each scan.
