Publication number: 20120162324Abstract: 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: ApplicationFiled: September 15, 2009Publication date: June 28, 2012Inventors: Paul Mark Haines, Ronald J. Ender, Craig L. Malik

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: 7862138Abstract: In one embodiment a pressure regulator for an ink pen includes: a diaphragm between a lower pressure region and a higher pressure region, the diaphragm movable toward the lower pressure region in response to an increase in a pressure difference across the diaphragm; a valve operative between an open position in which ink may flow into the lower pressure region and a closed position in which ink may not flow into the lower pressure region; a first lever rotatable on a first fulcrum in response to movement of the diaphragm toward the lower pressure region; and a second lever connected to the valve, the second lever rotatable on a second fulcrum in response to rotation of the first lever to move the valve from the closed position to an open position.Type: GrantFiled: October 4, 2007Date of Patent: January 4, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Paul Mark Haines, Mark A. Devries, Craig L. Malik, Ronald J. Ender

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
