A tip to be placed on a fluid-ejection device is filled with fluid. The fluid may be introduced into a substantially hollow body of the tip at a first end of the body. The body of the tip has a second end at which a fluid-ejection mechanism is disposed to eject the fluid as controlled by the fluid-ejection device. The fluid may be introduced into the substantially hollow body of the tip through of the fluid-ejection mechanism disposed at the second end of the body of the tip. The tip may further be identified and/or serviced, and the tip and/or the fluid-ejection device may further be validated.

Filling, identifying, validating, and servicing tip for fluid-ejection device

A fluid-ejection device includes a handheld and/or mountable enclosure, a removable tip, a cap, a pneumatic fitting, and a controller. The removable tip has a fluid-ejection mechanism located at an end thereof. The cap is disposed on the end of the removable tip such that just the fluid-ejection mechanism is exposed through the cap. The pneumatic fitting extends from the enclosure and is receptive to placement of the removable tip thereon. The controller is situated within the enclosure to cause the removable tip to eject fluid.

Handheld and/or mountable fluid-ejection device having removable tip with cap

A fluid-ejection device includes a handheld and/or mountable enclosure, a pneumatic fitting, an electrical connector, and a controller. The pneumatic fitting extends from and/or through the enclosure and is receptive to placement of a tip thereon. The tip contains a supply of fluid, a fluid-ejection mechanism, and an electrical connector for the fluid-ejection mechanism. The electrical connector extends from and/or through the enclosure and is receptive to electrical coupling of the electrical connector of the tip. The controller is situated within the enclosure to cause the tip to eject the fluid via the electrical coupling of the electrical connectors of the tip and the fluid-ejection device.

An air-driven delivery assembly for delivering marking material to a print head includes a supply reservoir configured to contain a quantity of marking material, a containment chamber coupled to the supply reservoir, and a low pressure source coupled to the containment chamber wherein activation of the low pressure source draws marking material from the supply reservoir into the containment chamber.

Air-driven delivery assembly

A single-piece print cartridge body is provided. The print cartridge has a plurality of outlet ports disposed along a single axis that is substantially perpendicular to a direction of motion of the print cartridge body during printing. First and second compartments are respectively communicatively coupled to first and second cavities. The first and second cavities are substantially parallel to the single axis and are located on opposite sides of the single axis. A first channel interconnects the first cavity and a first one of the plurality of outlet ports. A second channel interconnects the second cavity and a second one of the plurality of outlet ports. The first and second channels are substantially perpendicular to the single axis.
