摘要:
A housing defines a fluid reservoir for an imaging device. One or more exterior walls define a volume for holding ink to set a fluid backpressure in the imaging device. An opening in the walls is positioned for overflowing excessive ink from the volume to maintain the fluid backpressure within a predetermined operating range. Fluid inlets and outlets connect the reservoir to both a supply item and an ejection head. Ink flows into the reservoir from the supply item. It fills until the fluid rises to a height where it overflows back to the supply item. Less full reservoirs fill as the pump operates, while full reservoirs simultaneously return fluid back to their supply containers. Fluid does not spill from the walls.

A consumable supply item for an imaging device holds an initial or refillable volume of ink. An interior retains the ink while exit and return ports define openings through a housing to fluidly communicate the interior to the imaging device. The opening of the return port is larger than the opening of the exit port. The design slows the return of fluid to the housing which minimizes air bubbles or frothiness in the fluid. During use, ink depletes toward a bottom surface of the interior beneath which the ink is prevented from occupying. A housing section below the interior retains a portion of the exit port so that a bottom of the opening of the exit port is substantially horizontally aligned with the bottom surface. It prevents stranding ink beneath the exit port. Further embodiments include port configuration, construction, and modular components, to name a few.

A consumable supply item for an imaging device holds an initial or refillable volume of fluid. Its housing defines an interior having a pair of opposed electrodes. The electrodes define a capacitance that varies in response to an amount of liquid between them. A volume space filled by the liquid varies along a length of the electrodes. The design facilitates abrupt changes in capacitance values at each change in the volume space. Devices can recalibrate fluid levels at these changes. Electrode interior surfaces face one another. At least one electrode has an open region, such as a hole or a cutout of material. In another design, a support material connects to each electrode to provide mechanical stability and create a region preventing filling by the liquid. Further embodiments contemplate material selection, construction, and modularity, to name a few.

摘要:
An inkjet assembly comprising a vented ink reservoir for containing a liquid ink therein, the vented ink reservoir defining an internal volume occupied at least in part by a semipermeable membrane in fluid communication with a vent that automatically adjusts for pressure differentials by enabling gaseous diffusion between an environment external to the vented ink reservoir and the internal volume of the vented ink reservoir, while inhibiting liquid diffusion therethrough. A method is also disclosed for mounting the semipermeable membrane to at least one of an ink reservoir cap and an ink tank.

A printhead assembly includes a printhead body including at least one printhead having a wick associated therewith, and a shipping reservoir. The shipping reservoir is operable to releasably engage the printhead body and includes at least one vented ink container for retaining ink. The shipping reservoir is engaged in the printhead body during shipment so that the wick and ink flow channels with the at least one printhead remains moist while the shipping reservoir is engaged in the printhead body.
摘要:
Ink tanks and recording devices incorporating the ink tanks comprise a free ink chamber, and a negative pressure generating chamber in the ink tank. The negative pressure generating chamber comprises a floor member comprising at least one projection extending along at least a portion of the floor member, and a porous material, wherein the projection of the floor member is configured to engage the porous material to inhibit the creation of an air flow path between the porous material and the floor member. The ink tank further comprises a partition wall disposed between the free ink chamber and the negative pressure generating chamber and configured to allow the flow of ink from the free ink chamber to the negative pressure generating chamber.
摘要:
An ink jet cartridge for use in an ink jet printer. In one embodiment, the ink jet cartridge has an ink tank configured to hold a first capacity of ink. The ink tank comprises a negative pressure producing material containing chamber and a free ink chamber. A lid configured to seal the negative pressure producing material containing chamber and free ink chamber of the ink tank is adapted to reduce the volume of the ink tank from a first capacity to a second capacity of ink. A method of manufacturing the same is provided.
