  • Patent number: 8215631
    Abstract: An inkjet printing system comprising a media input support and a pivotable pick arm assembly including a pick roller. The assembly is biased to pivot toward the media input support. A rotatable arm is linked to the pivotable pick arm assembly and includes a ramped feature. The printing system further includes a carriage that includes a sloped feature that is in line with the ramped feature of the rotatable arm. When the sloped feature of the carriage is engages with the ramped feature of the rotatable arm the pick arm assembly is pivoted in a direction away from the media input support.

  • Patent number: 6450713
    Abstract: An output roller for propelling a media sheet, for example in a printer, is disclosed. A plurality of protrusions is selectively positioned on the output roller. As the media sheet exists a media path, the rear edge of the media sheet is caught by the protrusions and the rear edge is further pushed forward into an output stack. Preferably, the protrusions are flexible.

  • Patent number: 6148727
    Abstract: A printer having a system to manage the output path of wet printed media is disclosed. In such a system, the wet printed media are held for a time before being ejected into an output tray to avoid the smearing of the wet print markings made on the media. The system achieves this holding time by causing the wet printed media to travel an additional distance over movable ramps before being ejected. In addition, the movements of the ramps are synchronized with the various operations in the printing cycle of the printer.
