  • Publication number: 20160152026
    Abstract: In one example, a datuming system to position a printhead assembly relative to a component external to the printhead assembly includes first primary datum points and second primary datum points. The first primary datum points establish a first datum plane to position the printhead assembly relative to a first component external to the printhead assembly. The second primary datum points establish a second datum plane to position the printhead assembly relative to a second component external to the printhead assembly.

  • Publication number: 20050248617
    Abstract: The described embodiments relate to methods and systems for forming and protecting electrical interconnect assemblies. In one embodiment, an electrical interconnect assembly forming method forms an electrical interconnect between one or more conductors of a first support structure and one or more conductors of a second support structure. The method also distributes a generally flowable material over the electrical interconnect and exposes the generally flowable material to conditions sufficient to render the generally flowable material into a generally non-flowable state that provides fluid protection to the electrical interconnect and supports the electrical interconnect to reduce stress concentration at the electrical interconnect.

  • Patent number: 5450112
    Abstract: An ink cartridge for a thermal ink jet printer containing a separate collapsible ink reservoir which is kept under negative pressure by a pressure regulator to prevent ink leakage. The collapsible reservoir has one or more flexible sidewalls connected at their periphery to form an ink reservoir, wherein said sidewalls include a plurality of layers. The pressure regulator comprises a pair of spaced parallel side plates urged apart by a spring toward the adjacent reservoir sidewalls whereby the reservoir is collapsible against the spring pressure to an essentially flat shape to permit substantially complete dispensation of ink from the reservoir.

  • Patent number: 5440333
    Abstract: An ink cartridge for a thermal ink jet printer containing a separate collapsible ink reservoir which is kept under negative pressure by a pressure regulator to prevent ink leakage. The collapsible reservoir has a pair of flexible plastic membrane ink bag sidewalls each connected at their periphery to form an ink bag and an ink pressure regulator in the bag. The pressure regulator comprises a pair of spaced parallel side plates urged apart by a spring toward the adjacent bag sidewalls whereby the reservoir is collapsible against the spring pressure to an essentially flat shape to permit substantially complete dispensation of ink from the bag. Inadvertent puncture of the thin bag walls by the regulator is prevented by a protective edge guard in the form of a layer of tough plastic bonded to the outer surfaces of the sideplates, the protective layers each having a peripheral edge which extends beyond the edge of the side plate to prevent the edges of the sideplates from directly contacting the bag walls.
