  • Configurable scanner assembly
    Patent number: 8649073
    Abstract: A scanner assembly includes an automatic document feeder and a first scanner. The automatic document feeder defines a media pathway that includes an input portion and an output portion having an exit roller. The first scanner is positioned along the media pathway upstream from the exit roller. In a first assembled configuration, the assembly is configured to scan both a first side and a second side of the media via the first scanner. In a second assembled configuration, the assembly additionally includes a second scanner positioned along the output portion and interposed between the first scanner and the exit roller. In the second configuration, the assembly is configured to scan the first side of media via the first scanner and to scan the second side of media via the second scanner.

  • Automatic document feeder
    Patent number: 8613440
    Abstract: An automatic document feeding device including a pick motor coupled with a pick assembly, a deskew motor coupled with a deskew assembly, a sensor assembly coupled with a main media path and the deskew motor, and a feed motor coupled with a feed assembly. The deskew motor drives the deskew assembly, the deskew assembly deskewing the media sheet and moving the media sheet from the pick assembly to the feed assembly, the deskew assembly moving independently of the pick assembly and the feed assembly. The sensor assembly includes a plurality of sensors. The sensor assembly senses the media sheet moving along the main media path and sends at least one signal to a computer. The computer, based on the at least one signal, sends, an activation signal to at least one of the pick, deskew and feed motors and the first scanner.

  • Methods and apparatus for transporting sheet media
    Patent number: 7275741
    Abstract: A sheet handling assembly includes a frame, a first assembly, and a second assembly, each assembly rotatably supported by the frame and configured to contactingly transport sheet media. A member is configured to rotate the second assembly in response to rotation of the member in a first direction. The frame is configured to pivot in the first direction in response to rotating the member in the first direction, and pivot in a second direction, opposite the first direction, in response to rotating the member in the second direction.
