  • Patent number: 8591022
    Abstract: A pivotable duplexing unit is attached to the wall of a printer using a hinge having an axis that is substantially perpendicular to the base. A latch and catch holds the pivotable duplexing unit in a closed position relative to the wall of the printing apparatus. The wall includes a support member for the hinge, and the pivotable duplexing unit further includes a pin for pivoting in a support member of the hinge. The support member includes a bearing surface that is substantially parallel to the base. The pin member includes an end that makes pivotable contact with the bearing surface.

  • Patent number: 8235609
    Abstract: A method of adjusting the spacing between a portion of a printhead and a portion of a media support in a printing system. The spacing is easily adjustable at least at the time of manufacture for locking a printhead at a selected distance from the media support. A rotatable variable spacer is abutted against an anti-rotation rail to lock into place the printhead at the selected distance.
