  • Patent number: 6315282
    Abstract: An apparatus capable of performing pick operations on multiple sizes in a printing device is disclosed. This apparatus separates a media sheet from a stack and drives it along a media path. The apparatus also corrects any pick skew of the media sheet caused during the pick operation before the media sheet is transferred to the drive roller. By ensuring that the traversing media sheet has a leveled leading edge, the pick skew of the media sheet is substantially eliminated.
    Type: Grant
    Filed: June 22, 1998
    Date of Patent: November 13, 2001
    Assignee: Hewlett-Packard Company

  • Patent number: 6139011
    Abstract: A printer having a facility for manually directing a printing medium along a printing medium path. The printer includes an external housing, a drive roller arranged about an axis of rotation for feeding a printing medium through a processing zone of the printer, a control member arranged about an axis of rotation, and movable between a first axial position in which the control member protrudes from said external housing so as to be manually actuable, and a second axial position in which the control member is retracted relative to the first axial position, and a coupling mechanism selectively coupling the control member and the feed roller to translate rotational movement of the control member into rotational movement of the feed roller, said coupling mechanism being engaged when the control member is in the first axial position and disengaged when the control member is in the second axial position.
