    Abstract: A printable liquid supply cartridge (1) comprises a housing (2) enclosing an internal volume. The housing has a front end to connect to a printer and first and second sides (5, 6) extending from the front end to a rear end. The front end has a printable liquid outlet (7) closer to the bottom than to the top and has a gas inlet (8) above the printable liquid outlet, each of the printable liquid outlet and the gas inlet to facilitate insertion of a respective fluid pen therein. There is a recess (13) in the front end above the gas inlet, the recess being delimited by a first wall having an internal side and an external side that is part of the first side. An I2C data interface comprising at least three electrical connection pads are exposed on the internal side of the first wall facing towards the recess, the connection pads arranged in a top to bottom direction.

    Abstract: A fluid container usable with an image forming apparatus having a fluid container receiver is disclosed. The fluid container includes a housing unit including a free-fluid chamber to store a first fluid and a regulated chamber to store a second fluid. The regulated chamber includes a regulator unit configured to regulate the second fluid and an outlet configured to transport the second fluid outside of the housing unit. The fluid container also includes a fluid channel configured to establish fluid communication between ambient atmosphere and the free-fluid chamber, and a check valve configured to establish fluid communication between the free-fluid chamber and the regulated chamber.

    Abstract: In one example, a fluid cartridge includes a reservoir for holding a fluid, an electrical interface, an alignment feature, and a keying feature. The alignment feature is configured to, as the cartridge is inserted into a receiver, bias the electrical interface against a corresponding electrical interface on the receiver. The keying feature discriminates the cartridge from other fluid cartridges to prevent the cartridge from being inserted incorrectly into the receiver.

    Abstract: In one embodiment there is provided a sub-assembly of components to assemble a print liquid supply container, the set comprising a print liquid 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, wherein, in a filled and assembled state, starting at the neck, at least approximately two thirds of the bag projects in a direction parallel to the second dimension inside a projecting portion of the support structure, the support structure adapted to, in folded state, include approximately perpendicular walls defining said first, second and third dimension, the first and second dimension being more than the third dimension, wherein a first wall defining the second and third dimension includes an opening adjacent the neck of the reservoir when positioned in the support structure, to allow connection of another fluid structure to the neck, and the opening is provided adjacent another wall adjacent the first wall, opposite to the projecting portion, the other wall being parallel to the first and third dimension.
