Abstract: An ink delivery system for supplying ink to an inkjet printhead at a predetermined backpressure. The ink delivery system includes: a pressure regulating valve connected to a printhead inlet port; an ink tank connected to a valve inlet of the pressure regulating valve; and a pump connected to a printhead outlet port. The backpressure of ink supplied to the printhead is controlled by: a height h1 of ink in the ink tank relative to a valve orifice, a height h2 of the valve orifice relative to the printhead, a position of a valve member relative to the orifice and a pump speed of the pump.

Abstract: A printhead assembly that has a casing with a series of module mounting sites, printed circuit board mounting sites and busbar support formations. A printhead module is mounted to each module mounting site respectively. Each printhead module has a printhead integrated circuit (IC). A plurality of printed circuit boards control the printhead IC's, one of the printed circuit boards being fixed to each of the printed circuit board mounting sites respectively. Busbars are secured in the busbar support formations for receiving data and power from the printed circuit boards. The printhead modules are electrically connected to the busbars to provide the printhead integrated circuits with power and data.

Abstract: A method and system are presented which will detect combinations of user touches on a touch screen device as nodes, and will create shapes, areas and windows from these nodes. Where the device has a communications capability, the locally defined shapes, areas and windows can be shared with remote users and databases, and similarly shapes, areas and windows created by others can be viewed on a local display. The method and system are of particular benefit to drawing applications, windows definition on touch screen devices, real estate management, navigation, and exploitation of mapping resources.

Abstract: A printhead integrated circuit includes: an elongate silicon substrate having a frontside and a backside; a row of nozzle chambers disposed at the frontside of the substrate, each nozzle chamber having a respective nozzle opening defined in a roof thereof and a respective inlet defined in a floor thereof; a row of inlet channels defined in the substrate, each inlet channel having a first end defining the inlet of a respective nozzle chamber and an opposite second end; and an ink supply channel defined in the backside of the substrate, each ink supply channel having a depth sufficient to meet with the second ends the inlet channels. Each ink supply channel is elongate and extends longitudinally along a length of the substrate so as to provide fluidic communication between the backside and the nozzle chambers.

Abstract: Provided is a cartridge unit for a printer. The cartridge unit has upper and lower plate members having an ink bag located between the plate members to define an ink volume. The plate members can be displaced towards and away from each other by an external force. A bag constrictor assembly engages the plate members and is configured to act on the bag when the plate members are displaced towards each other to reduce the ink volume. A valve insert has an inlet valve to facilitate refilling of the bag with ink and an outlet valve to facilitate ink delivery to a printhead. A filter cover is positioned between the valve insert and the ink bag to filter contaminants and air bubbles passing between the ink bag and said valve insert.

Abstract: The invention provides for a printhead assembly that has a number of modular PCBs and a number of printhead integrated circuits (ICs). Each of the printhead IC's is respectively connected to one of the modular PCBs for operative control. Modular supports in the assembly define a raised portion and a recessed portion at an end thereof. Each PCB has electrical connecting strips which operatively overlie the respective recessed portions. At least one connecting member operatively connects respective PCBs to each other. Each connecting member has a series of parallel spaced conducting strips. The member is shaped and configured for fitment into a cavity defined by the raised and recessed portions of two abutting supports to connect the connecting strips of two PCBs via the conducting strips. The assembly also has a printer controller configured to synchronize operation of the respective PCBs during printing.

Abstract: A structure for an inkjet printhead is disclosed. The printhead structure has an elongate support structure for supporting a printhead integrated circuit, and ink conduits formed in the elongate support structure for supplying ink to an array of nozzles of the printhead integrated circuit. Each ink conduit includes cavities distributed along a roof of the ink conduit. An opening to each cavity has an upstream edge and a downstream edge. The upstream edge contacts the ink before the downstream edge during initial priming of the ink conduits from an ink supply. The upstream edge has a transition face between the ink conduit and the cavity interior, the transition face being configured to inhibit ink from filling the cavity by capillary action during initial priming of the ink conduit. This causes gas to be trapped within the cavity. The gas acts to compress pressure pulses in the ink.

Abstract: An ink manifold defining multiple fluid flow paths has openings arranged for detachable connection with conduits in an interface. Shut off valves at each of the openings respectively, are biased open. An actuator biased to a closed position by a resilient element, where it holds all the shut off valves closed. The actuator engages the interface such that moving the interface into connection with the openings simultaneously moves the actuator to an open position where the shut off valves are able to open. The resilient element generates a bias greater than a combined bias exerted by the shut off valves on the actuator.
