  • Apparatus for deskewing sheet media
    Patent number: 7823879
    Abstract: An apparatus for deskewing a media sheet includes a sheet feed system for transporting the media sheet along a media feed path in a media feed direction. A split alignment gate is positioned to intersect the media feed path. The split alignment gate subjects the media sheet to a deskewing force, wherein an amount of the deskewing force is determined based on a width of the media sheet in a direction transverse to the media feed direction.

  • Sheet picking system for an imaging apparatus
    Patent number: 7731176
    Abstract: A sheet picking system for picking a sheet of media includes a power source having a driveshaft. A first housing arm containing a drive gear is drivably coupled to the driveshaft. The drive gear defines a first pivot axis for the first housing arm, wherein the drive gear is driven by the driveshaft to rotate about the first pivot axis. A second housing arm contains an intermediate gear, a transmission device, and a pick roller. The transmission device is configured to rotatably couple the intermediate gear to the pick roller. The intermediate gear is positioned to be meshed with the drive gear. The intermediate gear defines a second pivot axis for the second housing arm. A link mechanism pivotably couples the first housing arm at the first pivot axis to the second housing arm at the second pivot axis.
