  • Patent number: 6357851
    Abstract: A hide-away wiper and wiper scraper system has a wiper that is extended to wipe ink residue from an inkjet printhead installed in an inkjet printing mechanism, and following wiping, ink residue is scraped from the wiper during retraction into a hide-away rest position inside the scraper mechanism. For cleaning several inkjet printheads, several such hide-away wipers may be provided in like number for cleaning the printheads. The hide-away nature of these wipers allows for independent movement of the wipers between their rest and wiping positions, which facilitates the uses of independent wiping routines tailored for the servicing needs of each printhead, or type of printhead. An inkjet printing mechanism having a hide-away wiping system, along with a method of cleaning one or more inkjet printheads, are also provided.
