Abstract: A method for fabricating a filter element to prevent contaminants from entering an ink supply inlet of an ink jet printhead. The filter is formed by laser ablation process in which output laser radiation is directed through a mask system or light transmitting system to create a filter hole pattern in a thin film. Slightly tapered holes are formed in the film, and the formed filter element is laminated to the ink supply inlet. The tapered holes provide improved flow/impedance and add increased structural strength.

Abstract: An ink-jet printhead chip in which digital image data is submitted to circuitry on a printhead, "mode signals" are periodically loaded into the printhead circuitry along with the image data. The mode signal can determine which of a plurality of subsets of ejectors in the printhead are to be activated at any given time. By iteration or manipulation of these mode signals, various specific print-quality techniques, such as entering a "draft mode" or altering the order of ejector activation across the array, can be carried out.

Abstract: A continuous stream type ink jet printhead utilizing constant thermal pulses to perturbate the ink streams emitted through a plurality of nozzles to break up the ink streams into droplets at a fixed distance from the nozzles whereat the drops are individually charged by a charging electrode in accordance with digitized data signals. Each printhead has a manifold, a plurality of ink channels communicating at one end with the manifold and terminating at the other end with nozzles, and at least one resistor addressed by a predetermined frequency of current pulses for applying thermal pulses to the ink. In one embodiment, a resistor is positioned in each of the channels adjacent the nozzles and in another embodiment, a single resistor is located in the ink manifold. The resistors are pulsed at low power to generate a perturbation of ink properties such as density, viscosity, or surface tension without producing a phase change in the ink.

Abstract: A thermally-conductive fluid ejector carriage device is used to dissipate heat from a thermal fluid ejector module in a fluid ejection device. The thermally-conductive fluid ejector carriage device is molded from a polymer, or a polymer material including at least one thermally-conductive filler material. The thermal fluid ejector module is brought into contact with the thermally-conducting polymer carriage to dissipate heat. The polymer can be a highly thermally-conductive polymer. A method of manufacturing the thermally-conductive polymer carriage includes molding the carriage at least partially from a polymer that includes thermally-conductive filler materials, and contacting the thermally-conducting polymer carriage with the fluid ejector module. A method for use of the thermally-conductive fluid ejector carriage device includes establishing a heat flow path from the fluid ejector module to ambient air through the thermally-conductive fluid ejector carriage device.
