摘要： 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.

摘要： A printhead for an inkjet printer that has a printhead integrated circuit (68) with nozzles for ejecting ink and a support structure (64, 174, 176) for supporting the printhead IC. The support structure having ink conduits (182) for supplying the array of nozzles. A plurality of cavities (200), each cavity having an opening that establishes fluid communication with the ink conduits, the openings being configured such that the cavities do not prime with ink when the ink conduits are primed from the ink supply. By leaving unprimed cavities throughout the support structure, any pressure pulses in the ink are damped by compression of the trapped gas pockets. Distributing the cavities rather than using one relatively large cavity, means that the pressure pulse is being damped along the length of the printhead IC, instead of allowing the pulse to travel the length of the ink conduit until it reaches the single damper and compresses the gas.

摘要： A thermal inkjet printhead with generally planar heater elements disposed in respective bubble forming chambers such that they are bonded on one side to the chamber so that the other side faces into the chamber. Each heater element receives an energizing pulse to heat ejectable liquid above its boiling point to form a gas bubble on the side facing into the chamber, whereby the gas bubble causes the ejection of a drop of the ejectable liquid from the nozzle. The chamber has a dielectric layer proximate the side of the heater element bonded to the chamber. The dielectric layer has a thermal product less than 1495 Jm−2K−1s−1/2, the thermal product being (ρCk)1/2, where ρ is the density of the layer, C is specific heat of the layer and k is thermal conductivity of the layer. The present invention reduces the drop ejection energy and the heat dissipation into the printhead IC by improving the thermal isolation between the heater and the substrate.

摘要： An inkjet printer that has an elongate array of nozzles for ejecting ink and ink conduits for supplying the array of nozzles with ink. The ink conduits are aligned with the longitudinal extent of the elongate array and have a plurality of pulse dampers individually in fluid communication with the ink conduits. Each pulse damper contains a volume of gas for compression by pressure pulses in the ink conduits, distributed along the length of the elongate array. A pressure pulse moving through an elongate printheads, such as a pagewidth printhead, can be damped at any point in the ink flow line. However, the pulse will cause nozzle flooding as it passes the nozzles in the printhead integrated circuit, regardless of whether it is subsequently dissipated at the damper. By incorporating a number of pulse dampers into the ink supply conduits immediately next to the nozzle array, any pressure spikes are damped at the site where they would otherwise cause detrimental flooding.

摘要： An ink coupling for connecting an inkjet printer and a replaceable cartridge configured to not drip ink upon detachment. The coupling has a cartridge valve on the cartridge side of the coupling and a printer conduit on the printer side of the coupling. The cartridge valve and the printer conduit having complementary formations configured to form a coupling seal when brought into engagement. The cartridge valve is biased closed and configured to open when brought into engagement with the printer conduit. Upon disengagement, the coupling seal breaks after the cartridge valve closes, and an ink meniscus forms and recedes from the complementary formations as they separate, the cartridge valve having external surfaces configured so that the meniscus travels across the external surfaces and only pins itself to the printer conduit surfaces. The invention keeps residual ink off the exterior of the cartridge valve by careful design of the external surfaces with respect to known receding contact angle of the ink meniscus. As the coupling seal breaks and the meniscus forms, the ink properties and hydrophilicity of the respective valve materials will determine where the meniscus stops moving and eventually pins itself.

摘要： A printhead for an inkjet printer that has a printhead integrated circuit (IC) with an array of nozzles for ejecting ink, and a support structure for mounting the printhead IC within the printer. The support structure has ink conduits for supplying the array of nozzles with ink, the ink conduits have a meniscus anchor for pinning part of an advancing meniscus of ink to divert the advancing meniscus from a path it would otherwise take. If a printhead consistently fails to prime correctly because a meniscus pins at one or more points, then the advancing meniscus can be directed so that it does not contact these critical points. Deliberately incorporating a discontinuity into an ink conduit immediately upstream of the problem area can temporarily pin to the meniscus and skew it to one side of the conduit and away from the undesirable pinning point. Once flow has been initiated into the side branch or downstream of the undesirable pinning point, it is not necessary for the anchor to hold the ink meniscus any longer and priming can continue.

摘要： A printhead for an inkjet printer, that has a printhead integrated circuit with an array of nozzles for ejecting ink and a support structure for mounting the printhead IC within the printer. The support structure has ink conduits for supplying the array of nozzles with ink. Within the ink conduits is a weir formation to partially obstruct ink flow so that when priming the printhead, the weir formation preferentially primes an upstream section the ink conduit. Using a weir downstream of areas that have a propensity to prime incorrectly can force them to prime more quickly or in preference to downstream sections. As long as the downstream section is one that reliably primes, albeit delayed by the weir, there is no disadvantage to priming the upstream section in preference.
