Patent number: 8721041Abstract: An ink collecting system has been developed to direct ink purged from a printhead positioned above an ink collecting tray along a stepped flow path into the ink collecting tray. The stepped flow path enables the purged ink to flow from a faceplate on the jet stack, around a junction, onto a lower surface of the jet stack, and to a curved lower flange of a reservoir housing, which directs the ink away from the faceplate before the ink drops into the ink collecting tray for disposal or reuse.Type: GrantFiled: August 13, 2012Date of Patent: May 13, 2014Assignee: Xerox CorporationInventors: Joseph Andrew Broderick, David Paul Platt, Isaac S. Frazier, Tony Russell Rogers

Patent number: 8256871Abstract: An inkjet printhead has been developed that includes an ink reservoir vent, which prevents ink from exiting the ink reservoir through the vent. The inkjet printhead includes a reservoir, an ink inlet, a vent opening, and a vent member. The reservoir contains a supply of ink and an air space above the supply of ink. The vent member extends from the vent opening and includes a first vent member opening positioned in an air space outside of the reservoir, a second vent member opening positioned in the air space above the supply of ink, and a vent channel configured to couple fluidly the first vent member opening to the second vent member opening. The second vent member opening is positioned within the reservoir to enable the second vent member opening to remain within the air space above the supply of ink regardless of a printhead orientation.Type: GrantFiled: September 30, 2009Date of Patent: September 4, 2012Assignee: Xerox CorporationInventor: David Paul Platt

Patent number: 8226187Abstract: An ink level control system includes a first dividing wall that divides a reservoir of a printhead into a first chamber and a second chamber. The first and the second chambers are each connected to the ink passages of the inkjet stack by an ink port. The first dividing wall includes an opening that connects the first chamber and the second chamber to enable ink to pass therebetween. The opening is located a predetermined distance above the bottom surface of the reservoir. An ink diverter is associated with the inlet opening that directs ink received through the inlet opening to one of the first and the second chambers in response to the reservoir being tilted in a first direction, and directs ink to the other of the first and the second chambers in response to the reservoir being tilted in a second direction.Type: GrantFiled: March 31, 2010Date of Patent: July 24, 2012Assignee: Xerox CorporationInventors: Trevor James Snyder, David L.
