  • Chamber and orifice shape variations in an orifice plate
    Patent number: 6454393
    Abstract: A method for making an orifice plate. The orifice plate defines both orifices and connected chambers. The orifice plate is constructed to permit, in the same print head, one chamber (or orifice) to be deeper (as well as, if desired, wider and longer) than another chamber (or orifice) that may be next to the first chamber.
    Type: Grant
    Filed: August 17, 2001
    Date of Patent: September 24, 2002
    Assignee: Hewlett-Packard Co.
    Inventors: Chien-Hua Chen, Antonio Cruz-Uribe
  • Inkjet printhead for wide area printing
    Publication number: 20020018101
    Abstract: A printhead is formed from a plurality of ink ejectors mounted on an inner surface of a rigid substrate while protruding through holes provided in the substrate. Electrical contact is provided on a surface of the ink ejectors common with the ink ejecting nozzles thereby avoiding vias to another surface. The rigid substrate provides a conducting layer on its inner surface such that the ink ejectors may be connected thereto with solder reflow techniques.

  • Ink chamber and orifice shape variations in an ink-jet orifice plate
    Publication number: 20010053501
    Abstract: A method for making an orifice plate for an ink-jet printer. The orifice plate defines both the orifices and the connected ink chambers. The orifice plate is constructed to permit, in the same print head, one chamber (or orifice) to be deeper (as well as, if desired, wider and longer) than another chamber (or orifice) that may be next to the first chamber. Similarly, a channel delivering ink to the first chamber may be configured to be deeper or shallower, as needed, relative to another channel in the orifice plate.
