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.

A solvent dispensing mechanism is fluidically coupled to create a substantially uniform wet region of a belt surface scrubber. Mechanisms for selectively engaging and disengaging the scrubber 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.

Dispensing applicator and method of use

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.

Dual-web transport belt cleaning apparatus and method

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.

Inkjet printer

A flipping wiper scraper system for cleaning several inkjet printheads in an inkjet printing mechanism has a wiper support mechanism which moves several elastomeric wipers across the printheads to wipe off accumulations of ink residue. This ink residue is then scraped off of the wipers to ready them for the next wiping stroke using a scraper system. The wiper support mechanism inverts the wipers to engage scraper bars of the scraper system. The scraper bars have scraping heads and capillary channels to draw liquid ink residue away from the heads through capillary forces. The scraper bars are arranged so only one or two wipers are scraped at any given time to reduce noise and quiet overall unit operation. A method of cleaning an inkjet printhead, along with an inkjet printing mechanism having such a flipping wiper scraper system are also provided.

Flipping wiper scraper system for inkjet printheads

A multi-tiered, multi-faceted, anti-flicking wiper scraper system cleans an inkjet printhead wiper without flicking or splattering ink residue onto other components in an inkjet printing mechanism. This system includes a scraper apparatus supported by a service station frame to contact the wiper through relative motion of the wiper and scraper apparatus. The scraper apparatus may take the form of two scraper bars which extend into the path of the wiper, with the first scraper bar being shorter than the second scraper bar, and with the first scraper bar being rigidly or pivotally supported by the frame. The scraper apparatus may be a unitary body defining two ramped wiping surfaces joined at an apex portion of the body, or a body having a scraping surface covered with a series of ridges. A method is also provided to clean ink residue from an inkjet printhead.
