  • Roll nip structure having adaptive pivot position
    Patent number: 8613444
    Abstract: A printing apparatus comprises a marking device, a media path positioned to supply sheets of media to the marking device, and a media supply tray positioned to supply the sheets of media to the media path. Further, a pair of rollers forms a nip adjacent the media supply tray. The rollers rotate in opposite directions to cause the sheets of media to move from the media supply tray to the media path. Additionally, a first frame structure supports a first roller of the pair of rollers. The first frame structure can be in a fixed position and holds the first roller in a fixed location. A second frame structure supports a second roller of the pair of rollers. The second frame structure is adjustable in a first direction toward the first roller and has a variable pivot position allowing the second frame structure to move in a second direction perpendicular to the first direction.
