Abstract: A printhead assembly includes a substrate to support a printhead die and an electrical circuit electrically coupled to the printhead die, with the substrate including a support surface to support the printhead die, a first rail to support the electrical circuit, and a second rail to support an adhesive between the electrical circuit and the substrate.

Abstract: Various embodiments and methods relating to an adhesive paste layer (34, 134) sandwiched between a flexible circuit (30) and a fluid delivery system (26) to form a seal at least partially about a print head (28) are disclosed.

Abstract: A printer assembly includes a carrier module and a first guide element. The carrier module includes side portions extending in a first orientation and a mounting portion to receive an ink cartridge. The first guide element is removably mounted on the carrier module and includes protrusions, extending outward beyond each side portion, to slidably engage a guide structure of a carriage cavity during at least a portion of removable insertion of the carrier module into the carriage cavity.

Abstract: An apparatus is provided, the apparatus including a printhead die, a base coupled to the printhead die, a flexible circuit mounted on the base and electrically connected to the printhead, and an adhesive sandwiched between the base and the flexible circuit. The base defines a trench with a sidewall having scallops formed therein. The adhesive is disposed in the trench to secure the flexible circuit to the base.

Abstract: In one embodiment, a component for dispensing a fluid includes: a plurality of fluid ejection orifices arrayed in a plane; and an elongated bumper extending along one side of the array generally in a plane intersecting the plane of the array and the bumper having a protruding exterior surface that includes a first part inclining away from the array and a contiguous second part inclining back toward the array.

Abstract: A fluid-ejection assembly includes a die, a substrate, ribs, and adhesive. The die has nozzles through which fluid is ejected. The substrate provides the fluid to the die. The ribs are within the substrate, and have rounded corners. The rounded corners are adapted to provide a predetermined characteristic. The adhesive affixes the die to the substrate.

Abstract: In one embodiment, a latch for a liquid dispensing component includes: a first part for holding a liquid dispensing component in a seated position in a holder, the first part movable between an open position in which the component may be installed in or removed from the holder and a closed position in which the component is held in the seated position in the holder; and a second part for connecting the component to a liquid supply port, the second part movable, while the first part is in the closed position, between a disconnected position in which the component is not connected to the liquid supply port and a connected position in which the component is connected to the liquid supply port.

Abstract: In one embodiment, a method for installing an ink cartridge includes: seating the ink cartridge in the carriage; holding the ink cartridge in the seated position; and while holding the ink cartridge in the seated position, connecting the ink cartridge to an ink supply port.

Abstract: A printing-fluid container includes a reservoir having a leading surface with an outer perimeter. Redundant interface elements are recessed from the leading surface interior the outer perimeter.

Abstract: A printing-fluid container includes a reservoir. An electrical interface is coincident with a first axis and includes a first leading surface or contact pad. A fluidic interface is coincident with a second axis and perpendicular to the first axis. The fluidic interface includes a second leading surface or entry point. The first void is recessed from the first leading surface or contact pad and the second leading surface or first entry point. The first void is coincident with the first axis. A second void is recessed from the first leading surface or contact pad and the second leading surface or second entry point. The second void is coincident with both the first axis and the second axis.
