    Abstract: An example printing fluid pressure sensor comprises a first pressurizable chamber having an inlet to receive a pressurized gas and a second chamber to receive a printing fluid. A flexible element is disposed in between the first and second chambers and is to retain a magnet. A first side of the flexible element forms a wall of the first chamber and a second side of the flexible element forms a wall of the second chamber to seal the first and second chambers. The example sensor further comprises a sensor to detect the position of a magnet relative to the sensor. The sensor is disposed outside of the first and second chambers.

    IPC: B41J2/175

    Abstract: In one example in accordance with the present disclosure, at least one print liquid supply interconnected is described. Each print liquid supply interconnect includes a housing movable relative to a printer and tethered via a feed hose to the printer. The housing includes at least one needle to be inserted in a print liquid supply to allow print liquid to move between the print liquid supply and an ejection device and two keyed slots disposed on either side of a first needle to gate insertion to a print liquid supply with protrusions that match the two keyed slots. The housing also includes a guide feature adjacent the first needle extending between a first keyed slot and the first needle and an electrical interface to establish a data transmission path between the print liquid supply and the ejection device, the electrical interface disposed between the first needle and a second keyed slot.

    Abstract: A print agent delivery system (100) comprises a printhead (140), a pump (120) to convey print agent along a delivery channel (130) to the printhead for ejection and a sensor (136) to monitor a property of print agent in the delivery channel. A controller (150) switches from operating a pump motor (122) driving the pump (120) at a first low speed condition to a second high speed condition, during a continuous printing operation, based on a signal received from the sensor (136) relating to the property and indicative of elevated demand for print agent at the printhead (140).

    IPC: B41J2/175

    Abstract: In one embodiment a print liquid supply apparatus is provided to supply liquid to a liquid needle of a receiving station comprising a liquid container including an at least partially collapsible liquid reservoir an interface structure at a side of the container, including a liquid channel that includes a reservoir connecting portion that fiuidically connects to the reservoir and a needle receiving portion to allow the liquid to flow from the reservoir to the needle; a liquid interface of the liquid channel adjacent the needle receiving portion and at a distance from the reservoir connecting portion, a front wail and/or edge adjacent the liquid interface including a push area which is disposed between the liquid interface and the container; and at least one key pen base and key pen protruding from the base in a direction parallel and opposite to the needle insertion direction; and a contact pad array next to the needle receiving liquid channel portion, in another example a sub-assembly of such apparatus is provided.

    Abstract: In one example in accordance with the present disclosure, at least one print liquid supply interconnect is described. Each interconnect includes at least one needle to be inserted into a print liquid supply to allow print liquid to move between the print liquid supply and an ejection device. Each interconnect also includes two keyed slots disposed on either side of a first needle to gate insertion of print liquid supplies to a print liquid supply with protrusions that match the two keyed slots. A guide feature of each interconnect us adjacent the first needle and extends between a first keyed slot and the first needle. An electrical interface of each interconnect establishes a data transmission path between the print liquid supply and the ejection device, the electrical interface disposed between the first needle and a second keyed slot.
