  • Patent number: 8500244
    Abstract: A structure for an inkjet printhead is disclosed. The printhead structure has an elongate support structure for supporting a printhead integrated circuit, and ink conduits formed in the elongate support structure for supplying ink to an array of nozzles of the printhead integrated circuit. Each ink conduit includes cavities distributed along a roof of the ink conduit. An opening to each cavity has an upstream edge and a downstream edge. The upstream edge contacts the ink before the downstream edge during initial priming of the ink conduits from an ink supply. The upstream edge has a transition face between the ink conduit and the cavity interior, the transition face being configured to inhibit ink from filling the cavity by capillary action during initial priming of the ink conduit. This causes gas to be trapped within the cavity. The gas acts to compress pressure pulses in the ink.

  • Patent number: 8485628
    Abstract: A printer is shown that can selectively reduce its print resolution by sharing print for one nozzle in the nozzle array between several nozzles. Each nozzle has an ejection aperture and a corresponding actuator for ejecting printing fluid through the ejection aperture. A print engine controller sends print data to the array of nozzles in accordance with a designated print job. During use, the print engine controller can selectively reduce the print resolution by apportioning print data for a single nozzle between at least two nozzles of the array. This recognizes that some print jobs do not require the best resolution—a lower resolution is completely adequate for the purposes of the document being printed. This serves to extend the operational life of all the nozzles.
