摘要： A detachable fluid coupling for connecting an inkjet printhead with an ink supply, the detachable coupling having a fixed valve member defining a valve seat, a sealing collar (146) for sealing engagement with the valve seat (148), a resilient sleeve (126) having one annular end fixed relative to the fixed valve member (128), and the other annular end engaging the sealing collar to bias it into sealing engagement with the valve seat. The coupling also having a conduit opening (150) that is movable relative to the fixed valve member for engaging the sealing collar (146) to unseal it from the valve seat. Unsealing the sealing collar from the valve seat compresses the resilient sleeve (126) such that an intermediate section of the sleeve displaces outwardly relative to the annular ends. With a resilient sleeve that buckles or folds outwardly, the diameter of the coupling is smaller that the conventional couplings that use an annular resilient element that biases the valve shut remaining residual tension. With a smaller outer diameter, the couplings for all the different ink colors can be positioned in a smaller more compact interface.

摘要： A printhead for an inkjet printer is disclosed. The printhead has one or more a printhead integrated circuits (ICs) with an array of nozzles for ejecting ink. A support structure of the printhead supports the printhead ICs. The support structure has ink conduits for supplying the array of nozzles with ink. Each ink conduit includes cavities distributed along a roof of the ink conduit. An opening to each respective 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 is 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： An ink supply arrangement for an inkjet printhead is provided having at least one collapsible ink bag containing ink for distribution to nozzles of the printhead via a fluid path between the ink bag and nozzles, a body for housing the ink bag and the printhead, and a biasing member in the ink bag. The ink is primed in the fluid path and nozzles so as to be ejected by the nozzles, in use, thereby depleting the ink contained in the ink bag. The ink bag is attached to the body at a wall opposite a wall of the ink bag facing the printhead. The biasing member applies outwardly directed force on the wall of the ink bag facing the printhead thereby maintaining substantially constant negative pressure at the nozzles as the ink is depleted. The fluid path connects the ink bag to at least 6400 nozzles of the printhead.

摘要： A method of priming an inkjet printhead having ink ejection nozzles. The method includes: providing an ink bag containing ink for distribution to the nozzles via a fluid path between the ink bag and the nozzles; applying inwardly directed force on at least one exterior wall of the ink bag so as to reduce an available fluid volume of the ink bag, thereby causing ink to flow from the ink bag to the nozzles along the fluid path; and arranging a biasing member in the ink bag so that the biasing member applies outwardly directed force on at least one interior wall of the ink bag to restrain the reduction of available fluid volume of the ink bag only once the available fluid volume has been reduced to a predetermined volume. Each nozzle is configured to eject an ink drop having a volume of about 1.2 picolitres.

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 the advancing meniscus 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 the advancing meniscus 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 the meniscus 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： 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.
