Publication number: 20190105897Abstract: An inkjet printing system, including an inlet in a print head to receive ink from an ink supply, a plurality of nozzles to eject ink in the print head, an ink pressure sensor disposed in an ink path, the ink pressure sensor configured to determine an ink pressure of the ink in the print head and output a signal indicating the ink pressure, and a controller in the print head configured to receive and process the signal indicating the ink pressure from the ink pressure sensor. The inkjet printing system may also include a memory to store an ink pressure and time profile. The controller may also output a signal to stop ejecting ink from the plurality of nozzles when the ink pressure is either below a negative threshold or above a positive threshold.Type: ApplicationFiled: October 10, 2017Publication date: April 11, 2019Inventors: Steven Ross Slotto, Jonathan R. Brick, David L. Knierim, Chad J. Slenes

Patent number: 9789697Abstract: A fluid sensor has a first electrode, a second electrode, a housing containing the first and second electrodes, such that the electrodes extend from the housing, exposed metal between the first and second electrodes, and a drive signal electrically connected to the second electrode, such that when fluid is present in the reservoir, either the first electrode senses the presence of the fluid, or the drive signal senses presence of the fluid. A fluid sensor has a first electrode, a second electrode, a housing containing the first and second electrodes, a drive signal electrically connected to the second electrode, and sensing circuitry to measure a current from the second electrode to indicate a fluid level.Type: GrantFiled: July 27, 2016Date of Patent: October 17, 2017Assignee: XEROX CORPORATIONInventors: David L. Knierim, Steven Ross Slotto, Blake Terry Weimer

Patent number: 8317309Abstract: A system for recycling waste phase change ink in a phase change ink imaging device includes a printhead having an on-board phase change ink reservoir and a waste ink collector for receiving ink from an ejecting face of the printhead. The printhead is supplied ink from a remote ink reservoir, which is also fluidly connected to the waste ink collector by a waste phase change ink conveyor, which is configured to convey melted waste phase change ink from the waste ink collector to the remote ink reservoir.Type: GrantFiled: March 16, 2012Date of Patent: November 27, 2012Assignee: Xerox CorporationInventors: Steven Ross Slotto, Britton T. Pinson, Clifford Alan Bell, Steven Van Cleve Korol, Brian Edward Williams

Patent number: 8162465Abstract: A system for recycling waste phase change ink in a phase change ink imaging device includes a waste ink collector positioned within a phase change ink imaging device to collect waste phase change ink produced by a printhead in the phase change ink imaging device. The waste ink collector includes a heater for heating the waste phase change ink in the collector to at least a phase change ink melting temperature. A waste phase change ink conveyor is configured to convey melted waste phase change ink from the waste ink collector to an ink reservoir for the printhead.Type: GrantFiled: November 20, 2008Date of Patent: April 24, 2012Assignee: Xerox CorporationInventors: Steven Ross Slotto, Britton T. Pinson, Clifford Alan Bell, Steven Van Cleve Korol, Brian Edward Williams

Patent number: 8147049Abstract: A method of recycling waste phase change ink includes collecting waste phase change ink in a container in a phase change ink imaging device. The waste phase change ink comprises melted phase change ink emitted by at least one print head in the phase change ink imaging device. The collected waste phase change ink is removed from the phase change ink imaging device, and at least a portion of the collected waste phase change ink removed from the imaging device is added to a quantity of melted phase change ink.Type: GrantFiled: November 20, 2008Date of Patent: April 3, 2012Assignee: Xerox CorporationInventors: Steven Van Cleve Korol, Steven Ross Slotto, Britton T.
