Abstract: An ink-jet printer cartridge having a center reservoir chamber and two side reservoir chambers for holding inks of three different colors is provided with ink flow pathways of special configuration for connecting the reservoir chambers to exit ports at the print element. The ink flow pathways are provided with ridges extending along substantially their entire lengths so that air bubbles cannot completely block ink flow through the pathways. The ink flow pathways are disposed such that they have a vertical component of direction over their entire length and the pathways connecting the side reservoir chambers to exit ports include duct portions disposed at compound angles relative to the axes of the cartridge so that air bubbles, because of their buoyancy, will naturally tend to drift upwardly through the inclined ducts toward the reservoir chambers during normal usage, or drift toward the exit openings when the cartridge is inverted for priming. The duct portions of the ink flow pathways are generally trapezoidal in cross-section, the side walls intersecting the top wall at acute angles so that air bubbles cannot completely block the duct portions. The duct portions have end surfaces for directing air bubbles toward the reservoir chambers during priming, the end surfaces being end faces of plugs.

Abstract: The invention provides a method for making ink feed vias in semiconductor silicon substrate chips for an ink jet printhead and ink jet printheads containing silicon chips made by the method. The method includes applying a first photoresist material to a first surface side of the chip. The first photoresist material is patterned and developed to define at least one ink via location therein. An etch stop material is applied to a second surface side of the chip. At least one ink via is anisotropically etched with a dry etch process through the thickness of the silicon chip up to the etch stop layer from the first surface side of the chip. As opposed to conventional ink via formation techniques, the method significantly improves the throughput of silicon chip and reduces losses due to chip breakage and cracking. The resulting chips are more reliable for long term printhead use.

Abstract: The invention provides a method for making piezoelectric printheads for ink jet The method includes applying an insulating layer to a first surface of a silicon wafer having a thickness ranging from about 200 to about 800 microns. A first conducting layer is applied to the insulating layer on the first surface and a piezoelectric layer is applied to the first conducting layer. The piezoelectric layer is patterned to provide piezoelectric elements on the first surface of the silicon wafer. A second conducting layer is applied to the piezoelectric layer and is patterned to provide conductors for applying an electric field across each of the piezoelectric elements. A photoresist layer is applied to a second surface of the silicon wafer, and the photoresist layer is imaged and developed to provide pressurizing chamber locations. The silicon wafer is then dry etched through the thickness of the wafer up to the insulating layer on the first surface of the wafer. A nozzle plate containing nozzle holes corresponding to the pressurizing chambers is applied and bonded to the second surface of the silicon wafer. As opposed to conventional wet chemical etching techniques, the method of the invention significantly decreases the manufacturing tolerances required and provides more reliable printheads for long term printer use.

Abstract: The invention provides a method for forming ink jet nozzle structures in an ablatable material. More particularly, the invention provides uniform nozzle structure by ablating an ablatable material with a laser beam while setting a field lens unit to various locations relative to a projection lens. The resulting ink jet nozzle structures have substantially orthogonal ink delivery trajectory paths relative to a plane defined by the length and width of the ablatable material regardless of the nozzles hole position relative to the edges of the ablatable material.

Abstract: A heater chip of a thermal ink jet printer has its entire surface, which is opposite the parallel surface having resistors for heating ink supplied from a cartridge body to nozzles in a nozzle plate, supported by and engaged with a surface of a base of a high thermally conductive radiator. The radiator, which is submerged in the ink in the cartridge body, has fins, which preferably have a surface area greater than the surface area of the base, extending upwardly from the base of the radiator. The cartridge body has surfaces, which are exposed to the ambient, with a surface area preferably greater than the surface area of the fins. Heat is transferred from the heater chip to the radiator base and from the fins of the radiator to the ink. The ink transfers heat to the ambient through the cartridge body.
