  • Cleaning medium for ink-jet hard copy apparatus
    Patent number: 7101033
    Abstract: A printing system includes a printhead, a movable transport surface opposite the printhead and configured to transport a print medium relative to the printhead, and a cleaning medium in contact with the transport surface while at least one of the cleaning medium and the transport surface are moved relative to one another.
    Type: Grant
    Filed: November 10, 2003
    Date of Patent: September 5, 2006
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Wesley Baxter Roche, Le Pham, Wade A. Powell, Steven P. Downing
  • Dual-web transport belt cleaning apparatus and method
    Patent number: 6923312
    Abstract: A method and apparatus for cleaning a perforated, transport belt has belt surface cleaner mechanisms that include a pair of moveable, consumable webs. A scrubbing of the belt by a wet web is followed by a scrubbing of the belt by a dry, absorbent web. A solvent dispensing mechanism can be fluidically coupled to re-soak the wet web. Mechanisms for selectively engaging and disengaging the belt surface cleaner mechanisms ensure free belt travel during flexible material transport and the cleaning of both surfaces during cleaning cycles. The system includes consumable piece-part elements for refurbishing and remanufacturing.

  • Cleaning medium for ink-jet hard copy apparatus
    Patent number: 6698878
    Abstract: A method and mechanism for cleaning a paper transport belt of undesirable ink deposits caused by ink-jet aerosol and printing overshoot operations uses a special cleaning medium. An absorbent material is positioned in the print zone of a hard copy apparatus to scrub the belt. An ink solvent is used to rehydrate dried ink. The scrubber can be in the form of consumable sheets or a continuous roll form.
