ABSTRACT:
In a color marking assembly, a series or plurality of ROS-imaging station units are aligned above an endless image transfer belt. Since there are a plurality of units, image alignment between the several station units is important. To accomplish this, skewing of each of the stations is necessary. The present invention involves a fixed ROS unit and a movable or skewable imaging station. This imaging station is movable on at least three spheres, one sphere below the imaging station and on its inboard side, the other spheres are located on a track below the imaging station and on its outboard side. This arrangement reduces vibration of these stations while at the same time providing an easily skewable xerographic imaging station.
