    Abstract: In some examples, a fluid ejection assembly is removably mountable in a system, and includes a fluid ejection device, and a removable frame on which the fluid ejection device is mounted. The removable frame includes a plurality of fluid interface members that share a common design to releasably engage with a plurality of fluid interface connectors together as the removable frame is brought into engagement with a support structure in the system and on which the plurality of fluid interface connectors are mounted. Engagement of a first fluid interface member with a first fluid interface connector establishes a gas path through the first fluid interface member and the first fluid interface connector, and engagement of a second fluid interface member with a second fluid interface connector establishes a liquid path through the second fluid interface member and the second fluid interface connector, the liquid path to deliver a liquid to the fluid ejection device.

    Abstract: Example continuous ink supply apparatus, systems and methods are disclosed. An example apparatus includes a housing; a printhead; and a regulator including a lever, a spring coupling the lever to the housing, a bladder, and a valve, a position of the lever relative to the housing being controlled by the bladder, the bladder being inflatable to urge the lever away from a surface of the housing and a plug of the valve to move away from a valve seat to enable fluid to flow through the aperture and into the housing, the regulator to enable a pressure within the housing to be maintained below a threshold pressure to substantially prevent fluid from inadvertently dispensing from the printhead.

    Abstract: Disclosed herein are sensor circuits for a replaceable print material container, the sensor circuit to communicate with a printer logic circuit. An example sensor circuit includes a first sensor to detect at least one of a pneumatic stimulus or a pressurization applied by a printer, a second sensor, and an interface to communicate with at least one of a voltage source or a data source of the printer logic circuit. The example sensor circuit also includes logic circuitry, responsive to a class parameter, to: (a) output a first signal based on at least one of the pneumatic stimulus or the pressurization sensed by the first sensor when the class parameter is a first class parameter; and (b) output a second signal based on at least one of an output of the second sensor, different data, or a different algorithm when the class parameter is a second class parameter.

    Abstract: An example pen housing includes a first regulator to actuate in response to a first pressure change to enable gas within a first chamber to flow from the first chamber to a second chamber, the first chamber to flow ink to a printhead, the second chamber not to receive ink directly from an ink supply; and a second regulator to actuate in response to a second pressure change to enable the gas received from the first chamber to be discharged from the second chamber.
