Abstract
A Raster Output Scanner (ROS) assembly is mounted within a printing machine frame so as to maintain a very precise relationship with the photoreceptor being imaged. A ROS housing is mounted in relation to the photoreceptor so that, while the housing is fixed to a machine frame by isolators to damp out vibrations and transients, a mechanical latching to a photoreceptor backer bar provides a degree of rotational movement consistent with movement of the photoreceptor. Thus, errors created by photoreceptor motion are compensated for. The invention discloses a 3 or a 4 point mounting arrangement which affords a high degree of stability coupled with conformance with exacting registration tolerances.
