ABSTRACT:
A system of mounting a raster output scanner relative to a photoreceptor such that deskewing, focusing, and pitch adjustment of the aerial image are possible. A spring isolated ROS assembly having at least two ROS arms attaches to a backer bar assembly that locates the position of the photoreceptor. The backer bar assembly and the ROS assembly connect at one end using a ball and socket and at the other end using a ball and fork such that the center line of the balls form a scan line plane. The ball and socket form a reference connection at one end. At the ball and socket end the photoreceptor backer bar has a mounting arm that is flexible in one plane but rigid in a perpendicular plane. A deskew mechanism, beneficially a motor driven cam, flexes the backer bar mounting arm as required to deskew the scan line.
