A print liquid supply apparatus comprising a container to hold print liquid and an interface structure to fluidically connect the container to a receiving station wherein the interface structure projects outwards with respect to the container and comprises a liquid interface to fluidically connect to a corresponding fluidic interface of the receiving station and a liquid channel fluidically connecting the container and the liquid interface.

Print liquid supply

A print liquid supply apparatus or interface structure to be connected to a print system comprises a liquid channel, liquid interface and integrated circuit contact pads.

An interface structure connectable to a separate liquid reservoir, to connect that liquid reservoir to a receiving station, comprising a liquid interface to fluidically connect to at least one liquid needle of the receiving station, a liquid channel, to fluidically connect the liquid interface to the reservoir, a support wall supporting an integrated circuit laterally next to the liquid channel, the integrated circuit having contact pad contact surfaces, and a front push area adjacent the liquid, the front push area terminating at a front edge that defines a profile height of the interface structure, between said front edge and an opposite distal edge.

A metered volume microfluidic device can include fluid flow microfluidics. The fluid flow microfluidics can include an inflow channel, a metered volume chamber positioned to receive working fluid from the inflow channel, a metered volume outflow channel positioned to receive and direct a metered volume of the working fluid when discharged from the metered volume chamber, and a capillary check valve. The capillary check valve can allow excess working fluid to exit the metered volume chamber when filling the metered volume chamber via the inflow channel. The capillary check valve can also prevent excess working fluid that has passed there through from being reintroduced into the metered volume chamber when the working fluid is discharged into the metered volume outflow channel.

Metered volume microfluidic devices

A print liquid supply interface structure is provided, to fluidically connect a fluid supply container to a receiving station, comprising a liquid channel having at least one liquid channel wall, the liquid channel including a liquid interface, and at least one key pen next and parallel to the needle receiving portion of the liquid channel. In another example a key pen structure is provided. In yet another example an interface structure for receiving a separate key pen is provided.

A printable liquid supply cartridge includes a printable liquid reservoir extending between a first side and a second side, and between a front end and a rear end. The front end includes a printable liquid outlet to receive a first fluid pen and a gas inlet, above the printable liquid outlet, to receive a second fluid pen. The front end also includes an interface support at the first side, the support having an I2C data interface that includes electrical connection pads exposed on an interior side of the support to face from the first side towards the second side, the electrical connection pads being arranged vertically and to make contact with the printer data interface at least partially inserted into the second portion.

Printable liquid supply cartridges

In one embodiment a sub-assembly of components is provided to assemble a print liquid supply container, the set including a reservoir and a support structure to form a print liquid supply container, the container having a first, second and third dimensions, the support structure to at least partially surround and support the reservoir and to provide stiffness to the container, at least in a folded and mounted condition, the reservoir including a bag to hold the print liquid, being at least partially flexible to collapse for print liquid to be withdrawn from the reservoir, the bag being configured to inhibit fluid exchange, and a neck that is relatively narrow with respect to the bag in a filled state, with an opening to output print liquid from the bag.

Examples of a print liquid supply unit are described herein. In some examples, the print liquid supply unit includes an electrical interconnect. In some examples, the electrical interconnect is sealed in a supply joint from an outside of the supply unit to an inside of the supply unit. In some examples, the supply joint is welded to join housing components of the supply unit.

Sealed interconnects

A logic circuitry package for a replaceable print apparatus component comprises an interface to communicate with a print apparatus logic circuit, and at least one logic circuit. The logic circuit may be configured to identify, from a command stream received from the print apparatus, parameters including a class parameter, and/or identify, from the command stream, a read request, and output, via the interface, a count value in response to a read request, the count value based on identified received parameters.

Logic circuitry

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 fluidically 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 wall 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.

A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit, and at least one logic circuit to transmit, via the interface, a sensor ID parameter and a limit parameter, the sensor ID parameter indicating a first sensor ID. The logic circuit is to receive, via the interface, a first request corresponding to the first sensor ID with the component connected to the apparatus and the apparatus not pneumatically actuating the component. The logic circuit is to transmit, via the interface, a first digital value in response to the first request. The logic circuit is to receive, via the interface, a second request corresponding to the first sensor ID with the component connected to the apparatus and the apparatus pneumatically actuating the component. The logic circuit is to transmit, via the interface, a second digital value in response to the second request. A difference between the first digital value and the second digital value is greater than the limit parameter.

Logic circuitry package

In an example, a method includes, by logic circuitry associated with a replaceable print apparatus component installed in a print apparatus, responding to a sensor data request received from the print apparatus by returning a first response; receiving a calibration parameter from the print apparatus; and returning a second response which is different from the first response.
