Patent number: 11807019Abstract: A printing fluid pen includes a plurality of fluid ports, a pressure regulator in fluid communication with a first fluid port, and a valve in fluid communication with a second fluid port. The first fluid port is to deliver printing fluid to a fluid ejection device, and the second fluid port is to direct printing fluid out of the pen. In response to negative pressure, the valve is to open to enable fluids within the pen to exit via the second port.Type: GrantFiled: July 31, 2019Date of Patent: November 7, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ronald Albert Askeland, Blair A.

Patent number: 8764173Abstract: A removable ink supply comprises an ink container including a coupler configured to removably engage a receiver of an ink supply station of an image forming apparatus. The coupler includes an end portion including an array of key holes with each key hole configured to removably receive a respective one key of an array of at least partially conductive keys of the receiver of the ink supply station. A conductive component of the coupler is positioned within the coupler and spaced apart from the end portion. The conductive component is in axial alignment with at least some of the respective key holes to be positioned for selective, removable contact with at least some of the respective keys of the receiver. An absence or a presence of removable contact between the conductive component and the key indicates an out-of-ink status of the image forming apparatus.Type: GrantFiled: September 15, 2009Date of Patent: July 1, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Paul Mark Haines, Ronald J. Ender, Craig L. Malik

Patent number: 8714720Abstract: An ink container for an inkjet print head includes a substantially rigid body of polymer material, the body including a base and a side wall integrally formed with the base at a perimeter of the base, the body containing ink in a low pressure chamber, and the polymer material having moderate to high air permeability. A flexible film is sealed over the low pressure chamber, inwardly flexible in response to a decrease in pressure and ink volume in the low pressure chamber, and outwardly flexible in response to an increase in pressure and ink volume in the low pressure chamber. A metal is coated on a perimeter of the polymer body and on an outer exposed surface of the flexible film, the metal to form a metal coating configured to decrease the air permeability of the polymer body, the metal coating being formed from at least copper.Type: GrantFiled: November 30, 2012Date of Patent: May 6, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Craig L. Malik, Mark A. DeVries, Paul Mark Haines, Ronald J. Ender

Patent number: 7922312Abstract: In one embodiment an ink pen for an inkjet printer includes: an ink filter chamber; a pressure regulator chamber downstream from the ink filter chamber along a path of ink flow through the pen; a pressure regulator in the pressure regulator chamber; a filter in the ink filter chamber; an inlet to the ink filter chamber upstream from the filter along the ink flow path; and an outlet from the ink filter chamber to the pressure regulator chamber downstream from the filter along the ink flow path such that ink flowing from the inlet to the outlet passes through the filter. In another embodiment a method implemented in an ink delivery system for an inkjet ink pen includes: chambering ink in the pen; filtering the chambered ink; and then regulating the pressure of filtered ink.Type: GrantFiled: April 24, 2007Date of Patent: April 12, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Paul Mark Haines, Mark A.

Patent number: 7618132Abstract: Damage is prevented in printing systems by allowing fluid from the printing system's fluid delivery system to expand. In one embodiment, this is accomplished by fluidly connecting a fluid expansion receptacle to the fluid delivery system. The fluid expansion receptacle provides volumetric compliance so that if printing fluid in the system expands, such as due to freezing, the fluid is able to expand into the fluid expansion receptacle and not damage the printing system.Type: GrantFiled: February 28, 2006Date of Patent: November 17, 2009Assignee: Hewlett-Packard Development Company, L.P.Inventors: Rhonda L. Wilson, Ronald J. Ender, Craig L. Malik
