  • Document handler/scan tub skew correction system
    Patent number: 7016640
    Abstract: An improvement in a skew adjustment system used in correcting skew between a document handler and a scan tub includes curved slots in a base portion of the document handler that are positioned for rotation over protruding members projecting from the surface of a movable portion of a hinge connecting the document handler to the scan tub. Rotation of the document handler generates a virtual pivot point what will increase the angular adjustment between the scan tub and the document handler while minimizing the misalignments.
