The foreign object location detector detects a pixel at a location of a foreign object adhered to an optical mirror of the image scanning mechanism by use of a first reference image data obtained by scanning a white reference plate by the image scanning mechanism at an initial operation after power-on of the scanner. The foreign object location storage stores a location of the pixel at the foreign object location in the main scanning direction detected by the foreign object location detector.Type: GrantFiled: November 24, 2009Date of Patent: March 26, 2013Assignee: Riso Kagaku CorporationInventor: Hayato Oumi

Patent number: 8400688Abstract: 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.Type: GrantFiled: December 28, 2010Date of Patent: March 19, 2013Assignee: Lexmark International, Inc.Inventors: Eugene David Allen, Chengwu Cui, Joshua Tyler Strow
