  • Droplet ejection apparatus
    Patent number: 6609778
    Abstract: A method for prevention of nozzle plate peel for inkjet printheads. The nozzle plate is bonded to the nozzle, with a layer of adhesive, and to a support, with a thicker layer of adhesive. This extra support prevents the peeling of the nozzle plate under the forces generated by, for example, a wiper blade passing over it. Spacers between the nozzle plate and support ensure the correct uniformity and constant thickness of the adhesive layer.
    Type: Grant

    Date of Patent: August 26, 2003
    Assignee: Xaar Technology Limited

  • Method of manufacturing of printing apparatus
    Patent number: 6260951
    Abstract: To allow accurate positioning relative to a printer mechanism, a printhead is provided with a reference surface formed on a reference member. The reference member is attached to the base of the printhead but positioned with reference to a nozzle of an ink ejecting unit mounted on the base member. This obviates the need for the base member to be manufactured to narrow tolerances.
