  • Print head maintenance system for an ink-jet printer using phase-change ink printing on a continuous web
    Patent number: 8366237
    Abstract: A maintenance assembly for cleaning a plurality of printheads in a printing machine comprises two or more cleaning members, each of the cleaning members sized and positioned to clean at least one but less than all of the plurality of printheads when in a cleaning position. A drive mechanism associated with each of the two or more cleaning members is configured to selectively move an associated cleaning member to and from the cleaning position and a retracted position. The cleaning members are supported on a frame with a mechanism provided for translating the frame into position juxtaposed with the plurality of printheads and a further mechanism to swipe the cleaning members across the printheads. The maintenance assembly is operable to clean only selected printheads in a single operation.

  • Xerographic printer split drive system to reduce image smear
    Publication number: 20060051141
    Abstract: A split drives system for a printer in which a single drive motor drives a first belt drive system for the image fusing system and a second and separate belt drive system driving the sheet registration system. This split drives system mechanically isolates the second and separate belt drive system from torque fluctuations in the image fusing system via the first belt drive system driving the image fusing system. Also, the split driving system can isolate torque variations in the driving of the print media fuser from the driving of the print media sheet transport.
