摘要:
A method for joining fluid containers and fluid ejectors in a fluid ejecting device are provided. The fluid container includes one or more heat stakes and a substrate includes one or more apertures for receiving the heat stakes and one or more three-dimensional features in the vicinity of the one or more apertures. The fluid ejector and optionally an elastic member are interposed between the fluid container and the substrate. Thermal energy is applied to the one or more heat stakes so that the one or more heat stakes soften to occupy the apertures and three-dimensional features of the substrate and pressure is applied to maintain contact between the fluid container, elastic member, fluid ejector and substrate. The present invention is also directed to substrate including one or more apertures for receiving heat stakes and one or more three-dimensional features in the vicinity of the one or more apertures.
摘要:
A system, method and structures for dissipating heat away from a thermal fluid ejector modules through a thermally-conductive carriage molded from a polymer to the ambient air surrounding the structure upon which the thermally-conductive fluid ejector carriage translates. The heat is transferred via conduction and convection from the thermally-conductive fluid ejector carriage across a thin volume of air trapped between a thermally-conductive carriage rod guide, enclosed on each end by thermally-conductive carriage rod guide bearings, and the thermal contact of the thermally-conductive carriage rod guide bearings with the surface of at least one thermally-conductive carriage guide rod which the thermally-conductive fluid ejector carriage translates.

An ink tank and ink tank support structure which contains structural elements which are designed to permit proper installation of the ink tank in the ink tank support structure while minimizing the chances of improper installation of the ink tank in the ink tank structure. A primary ink tank seal is provided in the ink tank, and a relatively low compressive force seal is provided between the ink tank support structure and the ink tank to reduce leakage of fluid from the tank and limit evaporation of fluid from the tank despite repeated insertions and removals of the ink tank from the ink tank support structure. A variable capacity ink tank and an ink tank with staggered height walls are disclosed, as well as a code reader for determining characteristics of ink tanks.

摘要:
A microelectromechanical system based fluid ejector comprises an ejector nozzle, a chamber that communicates with the ejector nozzle, and a plurality of movable ejection structures associated with the ejector nozzle and arranged to move in the chamber such that a variable volume of fluid is ejected from the associated ejector nozzle. The plurality of movable ejection structures may also be arranged to move in the chamber such that a continuous flow of fluid is ejected from the associated ejector nozzle. A controller may be used to actuate each of the plurality of movable ejection structures independently. The movable ejection structures may comprise a piston, a flexible diaphragm or the like. A plurality of actuators may be provided, with each of the actuators being associated with one of the ejection structures. The actuators may comprise electrostatic, magnetic or thermal actuators, or the like.

A printbar, such as a full width array printbar, filling method and apparatus provides for the selective application of positive pressure to an ink container, such as an ink bag, for forcing the expulsion of ink out of the bag and into the printbar. A steady force is applied until ink appears in a window provided in a vent line adjacent to and in fluid communication with the printbar, at which time the printbar manifold is full. Additional steady pressure forces ink to flow into the ink jet channels, assuring that the channels are fully primed and functional, at which time the positive pressure can be stopped. In an alternative embodiment, a motive force provided by, for example, a solenoid or motor, preferably including a gear and cam, are included to provide the motive force for the application of pressure against the ink bag. Pressure limiting springs may be utilized to provide the desired positive pressure to the ink manifold. A reflective light sensor may be included to detect ink in the vent line window and automatically turn off the motor or solenoid, preferably after a delay to allow priming of the channels.

A liquid ink printer, depositing ink drops to form an image, in multiple printing resolutions, on a recording medium moving along a recording medium path. The liquid ink printer includes a pagewidth printbar, including an array of ink ejecting nozzles spaced at a predetermined resolution, aligned substantially perpendicular to the recording medium path, to eject the ink drops on the recording medium during movement of the recording medium along the recording medium path, a positioning device, coupled to the pagewidth printbar, to position the printbar at a plurality of discrete locations, and a controller, coupled to the printbar and to the positioning device, to cause the positioning device to position the printbar at the plurality of discrete locations as a function of the predetermined resolution.

An ink jet cartridge has a rigid housing with a flexible, vent-free pouch containing ink positioned therein. The pouch has a fitment sealed therein with a quick disconnect valve incorporated in the distal end of the fitment which extends from the pouch. The housing protects the ink pouch from handling forces and provides the device to apply an insertion force necessary to install a cartridge into an ink supply station of an ink jet printer. Ink is extracted by a probe resident in the ink supply station which actuates the quick disconnect valve upon insertion of the cartridge. The quick disconnect valve reseals when the cartridge is removed from the probe. The quick disconnect valve has a spring biased ball and a resilient cap releasably snapped on the valve which has an internal conical wall that functions as a valve seat for the spring biased ball. The valve configuration reduces the number of parts and provides a larger and better surface for the ball to seal against.

A process for precision patterning or cutting of a sheet stock, such as an adhesive tape, includes the step of irradiating a surface of a sheet stock with an irradiation source to pattern or cut a part in the sheet stock. The method is particularly useful for precision cutting adhesive members, such as adhesive fluid seals, for an inkjet print cartridge.
