Abstract: A film sealed ejection cartridge assembly is disclosed. The cartridge assembly includes a cartridge for fluidic ejection, as well as a cartridge retainer having a plurality of retainer walls and a retainer opening. The cartridge retainer receives and secures the cartridge. The cartridge assembly further includes a length of a nozzle plate seal film. A first portion of the nozzle plate seal film is removably secured to the fluidic ejection chip and a second portion of the nozzle plate seal film is secured to the cartridge retainer. Removal of the cartridge from the cartridge retainer causes the nozzle plate seal film to separate from the fluidic ejection chip.

Abstract: A packaged fluidic ejection cartridge assembly is disclosed. The cartridge assembly includes a cartridge for fluidic ejection, a cartridge storage container, and a cartridge retainer rotatably attached to the container so as to rotate about a pivot axis. The cartridge retainer receives and secures the cartridge within the storage cup. A moisture barrier film is sealed over the storage cup. The storage container may be stored with the pivot axis in either a substantially horizontal position or a substantially vertical position. The center of mass of the cartridge retainer and the cartridge within the retainer are offset from the pivot axis so that the center of mass rotates to a position below the pivot axis when the packaged cartridge assembly is stored with the pivot axis in a substantially horizontal position.

Abstract: An ink container is provides ink to a vented printhead, where both the ink container and the vented printhead are positioned on a moveable carriage. The ink container receives ink from an off-carriage ink supply via an ink conduit. Air is removed from the printhead and ink container via a vacuum pump, coupled to an upper portion of the ink container via an air conduit. The vacuum pump is operable to pull air from the ink container by generating negative pressure in the ink container.

Abstract: A method of forming a conduit providing fluid communication between respective reservoirs of an ink tank, the method comprising the steps of: (a) forming a first orifice extending through a first external wall portion of an ink tank defining part of a first ink reservoir of the ink tank; (b) forming a second orifice extending through a second external wall portion of the ink tank defining part of a second ink reservoir of the ink tank; and (c) attaching a substrate over the first and second external wall portions at least about a first continuous seal line surrounding both the first and second orifices to define an external conduit communicatively connecting the first ink reservoir with the second ink reservoir.

Abstract: A method and system for purging bubbles from a fluid chamber of a micro-fluid ejection head containing a plurality of fluid chambers, an ejection actuator respectively associated with each of the fluid chambers, and a common fluid supply area for the fluid chambers. According to this exemplary method, one or more of the ejection actuators are pulsed with energy sufficient to expand a bubble present in one of the fluid chambers without substantially boiling the fluid in the common fluid supply area. A first temperature of the ejection head is maintained for a first period of time during bubble expansion so that the bubble in the fluid chamber is urged away from the fluid chamber. The ejection head temperature is decreased over a second period of time to lower the ejection head temperature to a second temperature lower then the first temperature.

Abstract: Some embodiments of the invention provide a printhead having a chip feed extending between an ink reservoir and printhead nozzles, wherein the chip feed has an inlet, and outlet, and one or more projections or recesses in a transition surface of the chip feed. The transition surface and the projection or recess can be inclined with respect to the outlet of the chip feed, and in some cases can be curved to present a concave or convex shape toward the outlet of the chip feed.

Abstract: A method of assembling a print head that includes the steps of: (a) providing a print head base including a nozzle and at least one ink channel; (b) mounting in fluid communication with the at least one ink channel of the print head base an ink regulator that includes: (i) a pressurized chamber including an ink inlet in fluid communication with an ink source, an ink outlet in fluid communication with the at least one ink channel of the print head base, and an exterior flexible wall having an inner surface facing an interior of the pressurized chamber, (ii) a valve biased to restrict fluid communication between the ink source and the pressurized chamber, where the exterior flexible wall actuates the valve to overcome the bias in response to a predetermined pressure differential across the exterior flexible wall to provide fluid communication between the ink source and the pressurized chamber, where the fluid communication between the pressurized chamber and the ink source decreases the pressure differential ac

Abstract: A replacement component for printing operations that includes a recess that is adapted to be engaged by a projection of a replacement component holder associated with a printing apparatus to mount the replacement component to the replacement component holder, the replacement component also including an actuatable release adapted to operatively contact at least one of the projection and the recess to substantially disengage the projection from the recess.

Abstract: A method of fabricating a delivery conduit adapted to provide fluid communication between an off-carrier ink source and a printhead, the method comprising the steps of: (a) providing an ink conduit adapted to be in fluid communication with an off-carrier ink source and a printhead; and (b) laminating a fluid barrier layer over the ink conduit to substantially inhibit at least one of permeation of a fluid into the ink conduit from an external environment and permeation of a fluid from the ink conduit to the external environment.

Abstract: Methods for disassembling at least two components of an inkjet printhead include applying heat, preferably in the form of laser energy, to one of the components and wholly or partially separating the components thereafter. The disassembly enables ease of refilling the inkjet printhead or replacing original parts. In one embodiment, the components comprise inkjet printhead lids and bodies originally laser welded to one another. In another aspect, methods of disassembly include laser unwelding inkjet printhead lids and bodies according to whether the inkjet printhead body embodies a mono or color ink body type through use of selective control of one or more laser light sources to illuminate the inkjet printhead lid in a specific pattern of light. Still other aspects include a disassembled inkjet printhead having components with laser welding residue thereon. The laser welding residue may have substantially matching edge lines between the two components.
