Abstract
A raster scanning optical system and method for adjusting a scan line location on a light receiving member by a desired amount. A photoreceptor receives a light beam as the photoreceptor is advancing in a slow scan direction. A polygon mirror scans the light beam across the photoreceptor at a scan line location extending in a fast scan direction. A light transmissive plate is located in the path of the light beam between the polygon mirror and the photoreceptor. The light transmissive plate is adjusted by an adjusting device to displace the scan line location on the photoreceptor by the desired amount in a direction parallel to the slow scan direction.
