Patent number: 10272690Abstract: In an example, a selection valve of a fluid supply system is disclosed. The selection valve selectively couples a source of pressurized air to one of first and second fluid supply cartridges, in the fluid supply system, to provide fluid to a printhead, the one of first and second fluid supply cartridges being coupled to the source of pressurized air at a time and other fluid supply cartridge being vented to the atmosphere. The selection valve includes a sleeve to provide interconnections with the source of pressurized air, the first and second fluid supply cartridges, and the atmosphere. Further, the selection valve includes a core disposed rotatably inside the sleeve to selectively couple the one of first and second fluid supply cartridges to the source of pressurized air and the other fluid supply cartridge to the atmosphere for switching the pressurized air between the first and second fluid supply cartridges.Type: GrantFiled: January 30, 2015Date of Patent: April 30, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Alfonso Cameno Salinas, Francesc Ros Cerro, Vicente Granados Asensio, Oriol Parera Fiestas

Patent number: 9770910Abstract: An image forming system includes a fluid applicator unit, a substrate positioning unit, and a fluid collector assembly. The fluid collector assembly includes a collector substrate, a collector advancement unit, and a collector control module. The fluid applicator unit may apply fluid to a substrate. The substrate positioning unit may position the substrate in a printzone to receive the fluid from the fluid applicator unit such that a first portion of the fluid remains on the substrate and a second portion of the fluid does not remain on the substrate. The collector substrate may collect the second portion of the fluid in the printzone below the substrate. The collector advancement unit may advance the collector substrate along a collector transport path below the substrate in the printzone.Type: GrantFiled: May 24, 2012Date of Patent: September 26, 2017Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Francesc Ros Cerro, Daniel Gutierrez Garcia, Marcia Sole Pons

Patent number: 9669634Abstract: A print head priming system comprises a vent closure section to close a vent, where the vent is to compensate backpressure in a print head. An inlet to receive pressurized gas from a source of pressurized gas is to provide the pressurized gas to the print head. A pressure relief valve is to open in response to pressure in the print head reaching or exceeding a predetermined value by the provision of gas to the print head by the source of pressurized gas.Type: GrantFiled: September 24, 2015Date of Patent: June 6, 2017Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Francesc Ros Cerro, Macià Solé Pons, David Ramírez Muela, Li Qian
