  • Patent number: 7637500
    Abstract: Embodiments of a method and apparatus for advancing a media sheet are shown and described in which a media sheet is urged along a media path toward a first position and a second position. The second position is downstream from the first position along the media path. As a leading edge of the media sheet reaches the first position, the leading edge is prevented from passing the first position for an initial time period while the media sheet is being urged along the media path. As the leading edge reaches the second position, the leading edge is prevented from passing the second position for a subsequent time period while the media sheet is being urged along the media path.

  • Patent number: 6749192
    Abstract: A media feed mechanism includes a picking device, a first feedroller and a second feedroller. The picking device picks a sheet of media from a media source. The first feedroller moves the sheet of media along a feed media path. During a skew correction phase, the first feedroller rolls in a forward direction feeding the sheet of media forward and the second feedroller turns in a reverse direction preventing the sheet of media from progressing past a nip of the second feedroller. This results in skew correction. After skew correction is performed, the second feedroller turns in the forward direction advancing the sheet of media for printing.
