Abstract: A modular ink jet ink delivery system comprising a print manifold including a passageway therethrough for the transfer of ink and a pen tower removably and operatively engageable with the manifold. The pen tower includes a central passageway for receiving and transferring ink from the manifold. A retainer member is operatively connected to the manifold. A first sealing member forms a first seal with the retainer member. A second sealing member forms a second seal with the pen tower such that when the pen tower and the manifold are operatively engaged with each other, a substantially sealed passageway is formed for the transfer of ink from the manifold to the pen tower.

Abstract: Methods and apparatus are disclosed for reducing the print-job completion time in a printing system having at least one printhead that is intermittently refilled from an “off-axis” ink supply during non-printing intervals. A reduced refill time is determined from an estimation of the amount of ink expended since the printhead was previously refilled, and on a characterization of the ink refill behavior of the printing system. The refill behavior of the printing system may be quantified in data stored in a memory device integral with a replaceable ink supply.

Abstract: The present disclosure relates to an inkjet printing system configured for receiving a replaceable ink container. The replaceable ink container has an ink extraction characteristic that varies with ink level in the replaceable ink container. The inkjet printing system includes an ink level determining device for determining ink level within the replaceable ink container. Also included is a control device for selecting a print mode based on ink extraction characteristics of the replaceable ink container.

Abstract: Disclosed is a pigmented fluid delivery system for an inkjet printing system. The pigmented fluid delivery system comprises a first printer component and at least a second printer component. The first printer component has a fluid outlet in fluid communication with a supply of pigmented fluid defined by particles suspended in a carrier fluid. The second printer component has a fluid inlet releasably connectable to the fluid outlet of the first printer component. The fluid inlet includes a filter compatible with the supply of pigmented fluid. The filter is an open weave screen defining a plurality of pores. The pores are sized to allow passage of the pigmented fluid while preventing clogging from flocculation of the particles and evaporation of the carrier fluid.

Abstract: An ink jet printing apparatus that includes a springbacked fluid interconnect seal that provides a seal between an ink handling component and an ink pipe that is attached to the ink handling component. The spring-backed fluid interconnection seal more particularly includes a generally conically tapered resilient seal, and a pre-loaded spring configured to axially extend or tension the seal. An exemplary embodiment of the invention includes a groove in the sealing face which allows the use of a liquid sealant. The groove holds the sealant in place through capillary forces, and also by virtue of trough-like shape protects the sealant from being wiped away through mechanical member.

Abstract: An ink containment and delivery system provides high sustained flow rates, allows higher “burst” (short time interval) flow rates, and allows bubble movement through the system conduits to the printhead, all while holding the printhead ink pressure in a range required for optimum printhead operation. The system includes an ink supply with a first, upstream pressure regulator which maintains a negative ink pressure within the ink supply. A second, downstream pressure regulator at the printhead maintains negative pressure in the printhead, and allows some compliance about the set point. The ink containment and delivery system allows drool-free separability of the ink supply and the printhead.

Abstract: The invention relates to an apparatus for inhibiting bubble formation during a chemical reaction. The apparatus comprises a base having a substantially planar surface with at least a portion of the surface representing a fluid contact area and a fluid comprising a liquid component in contact therewith. A cover and the base form an enclosure containing the fluid and a gas. A non-free-floating fluid-distribution member is provided that has a substantially flat surface in contact with the fluid. The member surface is disposed in an opposing and substantially parallel manner at a specified distance from fluid contact area. A gas-fluid interface having an interface radius is formed between the fluid and the gas. The apparatus also comprises means for maintaining a desired vapor pressure of the liquid component in the gas and means for immobilizing the cover with respect to the base. The interface radius is selected to result in a predetermined critical radius below which a bubble will shrink.
