An inkjet consumable cartridge having an inkjet cartridge having nozzles. The inkjet consumable cartridge also has an inkjet cartridge holding device for holding the inkjet cartridge, a cap configured to interface with the inkjet cartridge, and a cap actuator that, when actuated, moves the cap from a position where the cap does not interface with the inkjet cartridge to a position where the cap interfaces with the inkjet cartridge sealingly covering the nozzles. Furthermore, the consumable cartridge is removable from a printer as a self-contained unit.

Methods and systems for managing contaminants are described. One exemplary method ejects fluid from multiple ejection chambers of a printing device in a pattern designed primarily to create fluid flow to move a contaminant present in fluid contained in a fluid-feed channel configured to supply fluid to the multiple ejection chambers. Responsive to the ejection, the method moves fluid in the fluid-feed channel sufficiently to move a contaminant in a desired direction within the fluid-feed channel.

An adhesive joint with an ink trap is provided. The joint may be employed in a cartridge for an inkjet printer. The cartridge includes a headland region attached to a printhead assembly by an adhesive layer. The adhesive joint between the headland region and the printhead assembly include notches for retaining additional adhesive in order to reduce degradation of adhesive due to ink penetration. A method of assembling the printer cartridge to include an ink trap in the adhesive joint is also provided.

A manifold assembly for a fluid-ejection device having multiple-fluid type fluid-ejection printheads organized in a page-wide array includes a lower-most deck and an upper-most deck. The lower-most deck is to supply a first type of fluid and a second type of fluid to the fluid-ejection printheads. The first type of fluid and the second type of fluid are exterior-most fluids ejected by the fluid-ejection printheads in relation to a direction of media movement through the fluid-ejection device. The upper-most deck is to supply a third type of fluid and a fourth type of fluid to the fluid-ejection printheads. The third type of fluid and the fourth type of fluid are interior-most fluids ejected by the fluid-ejection printheads in relation to the direction of media movement through the fluid ejection device.

An ink cartridge for a thermal ink jet printer containing a separate collapsible ink reservoir which is kept under negative pressure by a pressure regulator to prevent ink leakage. The collapsible reservoir has a pair of flexible plastic membrane ink bag sidewalls each connected at their periphery to form an ink bag and an ink pressure regulator in the bag. The pressure regulator comprises a pair of spaced parallel side plates urged apart by a spring toward the adjacent bag sidewalls whereby the reservoir is collapsible against the spring pressure to an essentially flat shape to permit substantially complete dispensation of ink from the bag. Inadvertent puncture of the thin bag walls by the regulator is prevented by a protective edge guard in the form of a layer of tough plastic bonded to the outer surfaces of the sideplates, the protective layers each having a peripheral edge which extends beyond the edge of the side plate to prevent the edges of the sideplates from directly contacting the bag walls. The regulator is centrally positioned and held in place between the flexible membrane bag walls, preferably by heat bonding of the bag walls to the edge guards.
