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 spring-backed 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.
Abstract:
A volumetric fluid dispensing device can include a fluid reservoir having at least one flexible wall and a dispensing reservoir oriented above the fluid reservoir. The dispensing reservoir can have an overflow return fluidly connected to the fluid reservoir such that the dispensing reservoir holds a measured volume of fluid. A reservoir conduit can be fluidly connected to the fluid reservoir and the dispensing reservoir to allow excess fluid to return from the overflow to the fluid reservoir. A dispensing conduit can also be fluidly connected to the dispensing reservoir to allow fluid to exit the dispensing reservoir. A mechanical wall actuator can be operatively associated with the walls for controllably flexing at least a portion of the walls sufficient to force fluid from the fluid reservoir to the dispensing reservoir via the reservoir conduit.
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:
The present disclosure relates to a replaceable ink container for providing ink to an inkjet printing system. The inkjet printing system has a plurality of print modes with each print mode having an ink usage rate associated therewith. The replaceable ink container includes an information storage device containing print mode control information. The installation of the replaceable ink container into the inkjet printing system allows the print mode control information to be provided to the inkjet printing system. This print mode control information is used by the printing system for selecting a print mode from the plurality of print modes based on available ink within the replaceable ink container.
Abstract:
An ink supply for an inkjet printer is provided with a main reservoir, which is typically maintained at ambient pressure. The main reservoir, which has flexible side walls supported by a rigid frame, is coupled to a variable volume chamber via a check valve which allows the flow of ink from the reservoir to the chamber and limits the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet which is normally closed to prevent the flow of ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer.
Abstract:
An apparatus and method for removing air or other gases from a free-ink ink-jet pen is provided in a manner that does not waste ink or require disposal of purged ink. A gas separation and purge mechanism is incorporated into a pen body construct having an ink containment chamber such that gases will rise toward the mechanism. A vacuum is cyclically applied to the gas separation and purge mechanism to remove the gas and to allow the ink containment chamber to refill from a remote reservoir as needed.
Abstract:
The present invention is directed to an integrated cartridge assembly for delivery of the biocompatible fluids to a subject, in which the device comprises an integrated cartridge including a fluid reservoir for housing the biocompatible fluid, a dispenser permanently and fluidically connected to the fluid reservoir, and configured for dispensing the biocompatible fluid to a manifold which is fluidically and removably connectable to the cartridge.
Abstract:
Various apparatus and methods relating to determining a quantity measurement of fluid ejected by drop-on-demand nozzles and modifying the ejection parameters based upon the quantity measurement.
