Printhead For An Ink Jet Printer

US Patent:
4638328, Jan 20, 1987
Filed:
May 1, 1986
Appl. No.:
6/858143
Inventors:
Donald J. Drake - Rochester NY
William G. Hawkins - Webster NY
Roger G. Markham - Webster NY
Richard V. LaDonna - Fairport NY
Assignee:
Xerox Corporation - Stamford CT
International Classification:
G01D 1518
US Classification:
346 75
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.

Hybrid Ink Jet Printer With Alignment Of Scanning Printheads To Pagewidth Printbar

US Patent:
5751311, May 12, 1998
Filed:
Mar 29, 1996
Appl. No.:
8/624274
Inventors:
Donald J. Drake - Rochester NY
Assignee:
Xerox Corporation - Stamford CT
International Classification:
B41J 221
US Classification:
347 43
Abstract:
An ink jet printer is configured in a hybrid architecture wherein a full width printbar is combined with a partial width color scanning assembly to provide the capability of selectively printing in black only or, alternately, into producing color prints by operating the color scanning assembly exclusively. The cost of the hybrid system, when compared to a full width color system using four full width printbars, is greatly reduced. The partial width scanning assembly is mounted on a carriage which is stepped along a printing swath width, the sum of the incremental scan steps equaling the width of a full width printbar. A dimensional mismatch between the printbar and the scanning printhead in the direction perpendicular to paper motion (width direction) could result in image degradation because of misalignment of color drops to black drops. The mismatch could result in manufacturing errors in either the printhead width and/or the width of the carriage. It is proposed to identify the total mismatch as a distance. DELTA.

Ink Jet Printhead Which Avoids Effects Of Unwanted Formations Developed During Fabrication

US Patent:
5450108, Sep 12, 1995
Filed:
Sep 27, 1993
Appl. No.:
8/126962
Inventors:
Donald J. Drake - Rochester NY
Diane Atkinson - Webster NY
Assignee:
Xerox Corporation - Stamford CT
International Classification:
B41J 234
US Classification:
347 65
Abstract:
An improved thermal ink jet printhead is formed by the alignment and bonding of an anisotropically etched silicon wafer channel plate, containing a plurality of channel grooves, to a silicon wafer heater plate, containing a plurality of heating and addressing elements which are covered by a patterned thin and thick film insulating layer. The printhead enables better bonding of the two plates by sequentially patterning each layer of a two layer thick film layer to compensate for topographical features formed in the last thick film layer. The relative thickness and geometrical shapes of the recesses in the two layers are selected, so that topographic formations are varied to prevent standoff between bonded heater and channel plates, thereby insuring that the adhesive applied between the bonded plates will have the greatest propensity to bond.

Method Of Fabricating Precision Pagewidth Assemblies Of Ink Jet Subunits

US Patent:
5098503, Mar 24, 1992
Filed:
May 1, 1990
Appl. No.:
7/517178
Inventors:
Donald J. Drake - Rochester NY
Assignee:
Xerox Corporation - Stamford CT
International Classification:
B25B 1102, B23P 1900
US Classification:
156299
Abstract:
A method of fabricating extended arrays of image reading or writing subunits and in particular a pagewidth thermal ink jet printhead from a plurality of discrete thermal ink jet printhead subunits is disclosed. Each thermal ink jet printhead subunit includes a heater plate subunit having a plurality of resistive elements on an upper surface thereof and a channel plate subunit having a plurality of channels corresponding in number and position to the resistive elements on a base surface thereof, the upper surface of the heater plate subunit being attached to the base surface of the channel plate subunit to define a thermal ink jet printhead subunit having a plurality of channels forming nozzles with a resistive element in communication with each channel. The method includes the steps of forming a precision alignment structure such as a notch with, for example, a precision dicing saw, on an upper surface of each channel plate subunit, placing the upper surface of each discrete thermal ink jet printhead subunit on an elongated alignment substrate having a plurality of corresponding alignment structures, and engaging the upper surface of each discrete thermal ink jet printhead subunit with one of the corresponding alignment structures on the alignment substrate. These steps are repeated with subsequent thermal ink jet printhead subunits until an extended array having the length of, for example, a pagewidth is formed.

Printhead Element Butting

US Patent:
5755024, May 26, 1998
Filed:
Dec 18, 1995
Appl. No.:
8/573733
Inventors:
Donald J. Drake - Rochester NY
Mark A. Cellura - Fairport NY
Hung C. Nguyen - Buena Park CA
Assignee:
Xerox Corporation - Stamford CT
International Classification:
H05B 300
US Classification:
29611
Abstract:
A large array or pagewidth printhead fabricated from printhead elements or subunits. The printhead subunits are butted together at either adjacent channel elements or adjacent heater elements to form a pagewidth printhead. The butting element, either heater or channel element, is slightly wider than the non-butting element thereby providing gaps between the non-butting elements of a printhead element array. Where channel elements are used as the butting element, gaps between the heater elements provide for reduction or elimination of potentially damaging thermal compressive forces between adjacent heater elements. Where heater elements are used as the butting element, structural strength is increased since the heater wafer is stronger than the channel wafer. In addition, the width of the polyimide wall at the edges of the heater wafer is increased providing greater protection for thermal transducers located at the edges of individual heater elements.

Adhesive-Free Edge Butting For Printhead Elements

US Patent:
5572244, Nov 5, 1996
Filed:
Jul 27, 1994
Appl. No.:
8/280973
Inventors:
Donald J. Drake - Rochester NY
Hung C. Nguyen - Webster NY
Assignee:
Xerox Corporation - Stamford CT
International Classification:
G01D 1518, B41J 216, B41J 214
US Classification:
347 42
Abstract:
A large array or pagewidth printhead fabricated from printhead elements or subunits having adhesive-free butting edges. Each of the printhead elements includes a heater element and a channel element bonded together by an adhesive such as an epoxy. A space or adhesive-receiving aperture is formed between the channel element and the heater element before mating so that any adhesive forced from between the channel element and heater element by the pressure of mating does not flow onto the butting surfaces, but instead overflows into the space thereby maintaining an adhesive free butting edge. The channel element includes an etch trough which forms the space. The printhead elements are butted together to form a large array printhead. The absence of adhesive on the butting edges improves manufacturability of the large array printhead.
