  • Printer with sheet feeding past multiple printheads
    Patent number: 10173438
    Abstract: A printer includes: a first fixed printhead having a respective first print zone; a second fixed printhead positioned downstream of the first printhead relative to a media feed direction, the second printhead having a respective second print zone; an input roller assembly positioned upstream of the first platen, the input roller assembly being configured for feeding media sheets along a downward trajectory towards the first print zone; and an intermediary roller assembly positioned between the first and second print zones, the intermediary roller assembly being configured for receiving the media sheets from the first print zone and feeding the media sheets along a downward trajectory. The second print zone is positioned relatively lower than the first print zone.

  • Sheet feed mechanism for printer having wide print zone
    Patent number: 9796190
    Abstract: A printer includes: a first fixed printhead having a respective first print zone; a first platen positioned in the first print zone; a second fixed printhead positioned downstream of the first printhead having a respective second print zone; a second platen positioned in the second print zone; an input roller assembly configured for feeding media sheets along a downward trajectory towards the first platen; an intermediary roller assembly positioned between the first and second platens and configured for receiving the media sheets from the first platen and feeding the media sheets along a downward trajectory towards the second platen; and an exit roller assembly for receiving the media sheets from the second platen. The second platen is positioned relatively lower than the first platen to facilitate a stepped media feed path with minimal distance between the first and second printheads.

  • Belt assembly for high-speed inkjet printing
    Patent number: 9776439
    Abstract: A printer includes: a printhead assembly having a print zone and a belt assembly for feeding print media past the print zone in a media feed direction. The belt assembly includes: an endless belt tensioned between a first roller upstream of the print zone and a second roller downstream of the print zone; a drive mechanism for moving the endless belt in the media feed direction; and a fixed platen positioned in the print zone. The endless belt is guided around and below the fixed platen.
