  • Printhead and method of making the printhead
    Patent number: 8752939
    Abstract: A printhead assembly comprises a plurality of plates stacked together. The plates form a flow path having an inlet and a nozzle. An ejection chamber is in fluid connection with the flow path. A diaphragm is in operable connection with the ejection chamber. A micro actuator is in operable connection with the diaphragm, the micro actuator being configured to actuate the diaphragm. An adhesive layer bonds at least two of the plurality of plates together. The adhesive comprises silicone.
    Type: Grant
    Filed: June 29, 2012
    Date of Patent: June 17, 2014
    Assignee: Xerox Corporation

  • HSD wires using fibrous carbon nanomaterial yarns
    Patent number: 7738820
    Abstract: A Hybrid Scavengeless Development electrophotographic printing system is provided wherein the electrode wires contain carbon nanotube yarn. The use of carbon nanotube yarn alleviates the problem of fundamental strobing image defects, because the electrodes made from the carbon nanotube yarn can be put at a higher tension to density set point, and thereby achieve fundamental resonance frequencies larger than that obtainable from steel. Additionally the yarn's strength is sufficient to withstand the typical forces it is subjected to in a Hybrid Scavengeless Development environment.
