  • Inkjet printhead assembly with hybrid carrier for printhead dies
    Patent number: 6464333
    Abstract: An inkjet printhead assembly includes a carrier and a plurality of printhead dies. The carrier includes a substrate and an electrical circuit. The substrate has a first side and a second side such that the electrical circuit is disposed on the second side of the substrate. The printhead dies are each mounted on the first side of the substrate and electrically coupled to the electrical circuit Thus, the substrate provides support for the printhead dies while the substrate and the electrical circuit together accommodate fluidic and electrical routing to the printhead dies.

  • Electrical connection for wide-array inkjet printhead assembly with hybrid carrier for printhead dies
    Publication number: 20020051036
    Abstract: A wide-array inkjet printhead assembly includes a carrier and a printhead die. The carrier includes a substrate and an electrical circuit. The substrate has a first side and a second side such that the electrical circuit is disposed on the second side of the substrate. The printhead die is mounted on the first side of the substrate and electrically coupled to the electrical circuit. Thus, electrical connection is established between the first side of the substrate and second side of the substrate.

  • Diaphragm pump having an integral pressure plate
    Patent number: 6350024
    Abstract: The present invention relates to an ink supply of the type having a diaphragm pump that is actuated by an actuator for providing ink to a printhead. The diaphragm pump includes a diaphragm and a chassis. The diaphragm has an integral pressure plate portion formed therein. The chassis and the diaphragm define a variable volume chamber. The chassis has a bias portion disposed therein for engaging the integral pressure plate portion to urge the pressure plate in a direction away from the chassis. The pressure plate urges the diaphragm away from the chassis to expand the variable volume chamber.
