摘要： An illumination assembly for a scanner according to one example embodiment includes a scan head frame. A thermally conductive heat sink component has an elongated base portion that is mounted along a longitudinal edge of the scan head frame and a protruding portion having a generally L-shaped structure that includes a first portion extending from the base portion and a second portion extending from and generally orthogonal to the first portion. A light source is coupled to the second portion of the protruding portion of the heat sink component. A first reflector is removably coupled to the first portion of the protruding portion of the heat sink component and is positioned directly in the optical path of the light source.

摘要： A mounting bracket for an image sensing unit of a scanner according to one example embodiment includes a first portion and a second portion extending from the first portion. The first portion has a plurality of elongated holes therein each for receiving a fastener to mount the mounting bracket to a scan head frame. The second portion includes a cutout section therein for allowing an image sensor of the image sensing unit to receive an image from an optical unit of the scanner. A pivot hole in the first portion is centered about a width of the cutout section. When the mounting bracket is mounted on the scan head frame, the elongated holes in the first portion permit linear adjustment of the mounting bracket relative to the scan head frame and the pivot hole permits angular adjustment of the mounting bracket relative to the scan head frame.

摘要： An illumination assembly for a scanner according to one example embodiment includes a light source, a first reflector and a second reflector. The first reflector has a curved structure and is positioned directly in the optical path of the light source. The first reflector has a first portion and a second portion. The first portion of the first reflector is positioned to reflect light received from the light source toward a target area to be scanned. The second portion of the first reflector is positioned to reflect light received from the light source toward the second reflector. The second reflector is positioned to reflect light received from the first reflector toward the target area.

摘要： A printer assembly includes an idler pulley, a printhead carrier belt, an idler-pulley spring, and a ratchet stop. The printhead carrier belt is operatively connected to the idler pulley and extends in an inboard direction from the idler pulley. The idler-pulley spring biases the idler pulley in an outboard direction to maintain belt tension as the belt lengthens during wear. The ratchet stop is located inboard of the idler pulley and operatively engages the idler pulley against movement of the idler pulley in the inboard direction, wherein such inboard movement would cause printing errors.
