Patent number: 8702207Abstract: A fluid-ejection printhead die includes first fluid-ejection nozzles, second fluid-ejection nozzles, and a mixing barrier. The first fluid-ejection nozzles eject fluid of a first type, and are organized over a first row and a second row non-collinear to the first row. The second fluid-ejection nozzles eject fluid of a second type different than the first type, and are organized over a third row and a fourth row non-collinear to the third row. The fourth row is at least substantially collinear to the first row. The mixing barrier is at least substantially between the first row of the first fluid-ejection nozzles and the fourth row of the second fluid-ejection nozzles.Type: GrantFiled: May 17, 2009Date of Patent: April 22, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Joseph E.

Patent number: 6511166Abstract: An ink jet printing apparatus that includes a springbacked fluid interconnect seal that provides a seal between an ink handling component and an ink pipe that is attached to the ink handling component. The spring-backed fluid interconnection seal more particularly includes a generally conically tapered resilient seal, and a pre-loaded spring configured to axially extend or tension the seal. An exemplary embodiment of the invention includes a groove in the sealing face which allows the use of a liquid sealant. The groove holds the sealant in place through capillary forces, and also by virtue of trough-like shape protects the sealant from being wiped away through mechanical member.Type: GrantFiled: December 19, 2001Date of Patent: January 28, 2003Assignee: Hewlett-Packard CompanyInventors: Mark A. Smith, Peter R. Stokes, Jeffrey F. Bell, John L. Taylor, Daniel W. Petersen, David R. Otis, Jr.

Patent number: 6139137Abstract: A disposable/refillable inkjet cartridge with bubble generator and an adhesively attached bubble generator vent cover. The cartridge is filed through a bubble generator opening in the cartridge bottom eliminating a separate filling orifice and easing the priming operation. The vent cover is adhesively attached making removal for refilling easier and avoiding suspected problems related to welding flash in welded vent covers. The bubble generator includes a tapered opening which receives a ball. The ball contacts ribs extending longitudinally along a tapered portion of the opening. The ribs are spaced over an arc of the opening. A bubble forms as needed between the ball and opening to maintain back pressure. The ribs and taper produce more consistent bubble pressures. A single piece of tape over the bubble generator and printhead nozzles avoids common causes for depriming.Type: GrantFiled: June 24, 1998Date of Patent: October 31, 2000Assignee: Hewlett-Packard CompanyInventors: Ralph L. Stathem, John B. R. Dunn, Sandra J. Smith, Christopher P. Murschel, Lowell R. McDaniel, David L. Erickson, Kevin D. Almen, Peter R. Stokes, Wayne J. Traina

Patent number: 5442386Abstract: In one embodiment of the invention, a flexible tape has formed on it conductors for being connected to a printhead substrate. The conductors on the tape are coated with an insulating layer, and exposed ends of the conductors extend from the layer. A headland is formed on a plastic print cartridge for receiving the printhead substrate having the exposed conductors extending from one or more edges of the printhead substrate. An adhesive bead is formed on the headland so that when the printhead is properly positioned on the headland, the adhesive contacts the conductors to encapsulate and insulate one exposed side of the conductors. A second adhesive or encapsulant bead is deposited over the opposite side of the conductors to encapsulate and insulate the remaining exposed regions of the conductors. In this manner, the combined insulating action of the insulating layer and the two insulating adhesive beads prevents the conductors from being shorted together by ink which may flow in the vicinity of the conductors.Type: GrantFiled: April 30, 1993Date of Patent: August 15, 1995Assignee: Hewlett-Packard CompanyInventors: Winthrop D.
