    摘要： A fluid ejection cartridge (10) having a cartridge body (12) with a cavity therein and an ejection head (16) attached to an external surface of the cartridge body (12) opposite the cavity. A cylindrical or a rectangular prism-shaped body (14) made of a hydrophilic open-cell foam material is disposed in the cavity of the cartridge body (12). The cylindrical or rectangular prism-shaped body (14) has at least one uncoated hydrophilic surface (42) and two or more surfaces (30, 32, 34, 36, 38) coated with a hydrophobic material (40).

    摘要： A small form factor printhead and a thermal inkjet printer containing the small form factor printhead are provided. The printhead includes an ink reservoir body having four sidewalls (34a, 34b, 34c, 34d) connected to a bottom wall (34e). An ink supply port (72, 74) is disposed in the bottom wall. An ejection head (42) is attached to an exterior surface of the bottom wall, wherein the ejection head is in ink flow communication with the ink supply port. A flexible circuit (44) is electrically connected to the ejection head and is attached to the exterior surface of the bottom wall and an exterior surface of one of the four sidewalls. A cover (36) is attached to a distal end of the four sidewalls opposite the bottom wall. A filter (46) is attached adjacent to an underside of the cover.

    摘要： A printing fluid cartridge a printing fluid cartridge is configured to be inserted into a printing fluid consuming apparatus in an insertion direction. The printing fluid cartridge includes: a storage chamber, a supply portion, a rear surface, an upper surface, an electrical interface, a locking surface, one protrusion, and another protrusion. The storage chamber is configured to store printing fluid. The one protrusion and the another protrusion define a plurality of imaginary planes each of which passes through the one protrusion and the another protrusion. The plurality of imaginary planes includes a specific imaginary plane. The specific imaginary plane is positioned higher than any other imaginary plane between the one protrusion and the another protrusion. The electrical interface is positioned downward relative to the specific imaginary plane in the gravitational direction in the attached posture.
