Abstract: A system for calibrating a scan module of an automatic document feed (ADF) scanner. The system includes a rotatable frame disposed on a position opposite to an imaging surface of the ADF scanner. An image backer and a calibration surface portion formed along longitudinal portions of the frame extend substantially parallel to the imaging surface. The image backer and calibration surface portion have top surfaces of different reflectivity that respectively does not contact and contacts the imaging surface when the frame is rotated to position the image backer and the calibration surface portion in a field of view of the scan module. A drive mechanism coupled to the frame is controlled by a controller to rotate the frame and selectively position within the field of view of the image capture module the image backer during a scanning operation and the calibration surface portion during a calibration operation.

Abstract: An illumination assembly for a scanner comprising a light source, a primary reflector and a secondary reflector. The primary reflector comprises a lower member and upper member spaced away from the lower member. The upper member has a heatsink for dissipating the heat of the light source. The light source is positioned between the lower and upper members and is attached to the upper member allowing for decreased vertical height for the illumination assembly.

Abstract: 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.

Abstract: An optical system for a scanner according to one example embodiment includes a light source for illuminating a target area and a plurality of mirrors that includes a first mirror positioned to receive a light beam traveling along a first optical path and to reflect the beam along a second optical path. A second mirror receives the beam traveling along the second optical path and reflects the beam along a third optical path. A third mirror receives the beam traveling along the third optical path and reflects the beam along a fourth optical path. A fourth mirror receives the beam traveling along the fourth optical path and reflects the beam along a fifth optical path. A fifth mirror receives the beam traveling along the fifth optical path and reflects the beam along a sixth optical path. An image sensor receives the beam and senses an image of the target area.

Abstract: 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.

Abstract: 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.

Abstract: A tubular structure with an opening defined thereon and having an inner surface and an outer surface. The tubular structure being substantially circular in shape and is made of a highly thermal conductive material. A plurality of light sources mounted on the inner surface of the tubular structure. The inner surface is coated with a diffused white coating. Light emitted from the plurality of light sources is reflected from the inner surface before exiting the tubular structure from the opening. This structure ensures emitting a uniform diffused light and prevents non-uniform illumination when disposed in an imaging forming device.
