  • Patent number: 8659803
    Abstract: An image forming device including a print unit having a housing and a scan unit disposed on the top surface of the housing. The scan unit is coupled to the housing such that the scan unit is operable to scan an image in an upright position and in a horizontal position. The coupling includes the scan unit slidingly engaging with the print unit along a first edge of the scan unit. A linkage member is pivotably coupled to the scan unit and the print unit for supporting the scan unit in the upright position.
    Type: Grant

  • Publication number: 20100118327
    Abstract: An all-in-one device including a printer and an image capture unit disposed substantially within a housing, the image capture unit including a transparent platen and capturing an image of a media sheet positioned against the platen. The platen is substantially vertically positioned along a front portion of the housing. The image capture unit may further include a lid that is movable relative to the platen between open and closed positions, and a video monitor integrated within an outer surface of the lid and sized to serve as a monitor for a computing device.

  • Patent number: 6315386
    Abstract: An ink jet printer includes a printer frame and a maintenance station coupled to the printer frame. The maintenance station includes a maintenance frame having a first side. The first side has formed therein at least a first guide slot and a first flexible end-stop member associated with the first guide slot. A maintenance sled is provided which is movable within the maintenance frame in a first direction. The maintenance sled has a first guide member positioned to slideably ride in the first guide slot. A travel limit of the first guide member in the first direction is defined by the first flexible end-stop member.

  • Patent number: 5971390
    Abstract: Each sheet of a stack of media is aligned with a fixed alignment surface prior to being fed towards a process station of a printer by a single pick roll. During the first portion of its cycle of operation, the sheet advancing force of the pick roll, which is offset from the axis or centerline of the sheet, exerts a torque on at least the uppermost sheet of the stack to have one of its sides engage the alignment surface if it is skewed. When the one side of the sheet is not engaging the alignment surface when the pick roll is initially energized, the uppermost sheet's leading edge engages a resilient projection of an insert of a rib, which is offset from the axis of the sheet but farther from the alignment surface than the pick roll. The skewed sheet pivots about the projection, which is formed of a high coefficient of friction material, extending beyond the surface of the rib. During the remainder of its energization, the pick roll advances the sheet towards the process station of the printer.
