Abstract: 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.

Abstract: A fluid transport conduit for conveying ink-jet ink from a reservoir to a printhead in an ink-jet printer is provided. The fluid transport conduit comprises at least one inner layer, such as high density polyethylene, cyclic olefin copolymer, or polypropylene homopolymer, that is flexible and is a barrier to liquids, and at least one outer layer, such as nylon or polyvinyl alcohol, that is a barrier to air and is softer, or more compliant, than the inner layer, with the inner layer bonded to the outer layer. The two layers are advantageously co-extruded to form the fluid transport conduit.

Abstract: A service station for use in servicing one or more inkjet print cartridges includes a service station sled assembly movably attached to a service station chassis. The sled assembly includes at least one wiper and at least one cap. In one embodiment, the service station includes a cam and cam follower that interact to move the sled assembly. The cam is shaped so that movement of the cam to a first position causes each cap to contact a printhead of a corresponding inkjet print cartridge. Movement of the cam to a second position causes the cap to move away from the printhead and moves the wiper into a wiping position. In another embodiment, a service station according to the invention for use with a facsimile machine including inkjet printing apparatus includes a motor that is positioned so as to minimize the footprint of the service station.

Abstract: A storage and spittoon system is provided for an inkjet printing mechanism to handle waste inkjet ink that has been spit from an inkjet printhead during a nozzle clearing, purging or “spitting” routine. A rotating spit wheel has a rim with a concave cross sectional shape which receives ink residue spit from the printhead. A compliant scraper is spring biased to contact the spit wheel rim at a substantially tangential orientation to scrape the ink residue from the rim as the wheel is rotated past the scraper. The scraper directs the ink residue into a storage container as a string-like strip which is then packed to into a storage container as the spit wheel rotates. A method of purging ink residue from an inkjet printhead, along with an inkjet printing mechanism having such a waste ink storage and spittoon system, are also provided.
