A printhead reservoir has an ink input port, an ink reservoir to hold ink received through the ink input port, an ink channel to pipe ink to the jets, and an air vent at the top of the channels to vent the air bubbles from the jet ink path when pressure is applied. The air vents have channels separate from the jetting fluid path that exit the jet stack.Type: ApplicationFiled: December 5, 2006Publication date: June 5, 2008Applicant: XEROX CORPORATIONInventors: David P.

Patent number: 6003971Abstract: An ink jet array print head (101) includes four media-width linear ink jet arrays (100). Ink flows from four sets of manifolds (106) through acoustically matched inlet filters (116), inlet ports (117), inlet channels (118), pressure chamber ports (120), and ink pressure chambers (122). Ink leaves the pressure chambers through outlet ports (124) and flows through oval outlet channels (128) to orifices (108), from which ink drops (110) are ejected. The ink pressure chambers are bounded by flexible diaphragms (130) to which piezo-ceramic transducers (132) are bonded. To minimize inter-jet cross-talk caused by pressure fluctuations in the manifolds, compliant walls (150) form one wall along the entire length of each manifold. An improved ink feed system (210) supplies four colors of ink to the print head.Type: GrantFiled: March 6, 1996Date of Patent: December 21, 1999Assignee: Tektronix, Inc.Inventors: David W. Hanks, Meade Neal, Sharon S. Berger, Donald B. Maclane, Nasser Alavizadeh, Ronald F. Burr, William H. Tomison

An ink feed system (200) supplies four colors of ink to the print head. Phase-change inks are melted and deposited in ink catch basins (202), funneled into ink storage reservoirs (204), and fed to the-print head through ink stack feeds (206).Type: GrantFiled: January 13, 1995Date of Patent: May 25, 1999Inventors: Ronald F.

Patent number: 5689291Abstract: An ink jet (10, 200) provides high-resolution gray scale printing or switchable resolution printing by providing PZT drive waveforms (100, 110, 120, 360, 370), each having a spectral energy distribution that excites a modal resonance of ink in an ink jet print head orifice (14, 208). By selecting the particular drive waveform with selectable energy inputs that concentrates spectral energy at frequencies associated with a desired oscillation mode and that suppresses energy at the other oscillation modes, an ink drop (170, 180, 190, 210) is ejected that has a diameter proportional to a center excursion size of the selected meniscus surface oscillation mode. The center excursion size of high order oscillation modes is substantially smaller than the orifice diameter, thereby causing ejection of ink drops smaller than the orifice diameter. Conventional orifice manufacturing techniques may be used because a specific orifice diameter is not required.Type: GrantFiled: January 11, 1995Date of Patent: November 18, 1997Assignee: Tektronix, Inc.Inventors: David A. Tence, Sharon S. Berger, Ronald F. Burr

Patent number: 5610645Abstract: A particulate filter (16) is provided within an inlet channel (22) of an ink jet (14). The filter is oriented generally in the direction of ink flow to provide a greater filter surface area. Positioning the filter within the inlet channel results in reduced acoustic crosstalk, more effective filtering, and more efficient purging of the filter itself because of the relatively high ink pressure drop across the filter in the channel. Positioning the channel vertically assists the buoyancy of the bubble movement during operation and purging.Type: GrantFiled: April 30, 1993Date of Patent: March 11, 1997Assignee: Tektronix, Inc.Inventors: John S. Moore, Sharon S. Berger, Ronald F. Burr, Jeffrey J. Anderson, Donald B. MacLane
