Patent number: 9724922Abstract: A method of removing printing fluid puddles from an exterior nozzle surface of an inkjet printhead includes selectively applying a suction signal for a first time period to a plurality of actuators associated with fluid channels of corresponding nozzles by a control module. The method also includes moving printing fluid within the fluid channels associated with the actuators in response to application of the suction signal. Additionally, the method also includes creating suction in each one of the associated fluid channels and through the corresponding nozzles to remove the printing fluid puddles from the exterior nozzle surface by pulling the printing fluid puddles through the corresponding nozzles and the associated fluid channels in response to movement of the printing fluid within the fluid channels.Type: GrantFiled: July 29, 2013Date of Patent: August 8, 2017Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Semion Gengrinovich, Harel Malka, Alexander Markman

Patent number: 9707764Abstract: The method of operating an inkjet printing system includes ejecting usable fluid on a substrate in a print mode and in a purge container in a maintenance mode by a print head. The method also includes receiving recovered fluid from the purge container and source fluid from the source supply to form the usable fluid in a primary fluid tank. The method also includes receiving and providing an amount of the usable fluid from the primary fluid tank to the print head by at least one of a first supplemental fluid tank and a second supplemental fluid tank. The method also includes determining a consumed amount of the usable fluid corresponding to an amount of the usable fluid used by the print head reduced by an amount of the recovered fluid received by the primary fluid tank from the purge container.Type: GrantFiled: September 27, 2012Date of Patent: July 18, 2017Assignee: Hewlett-Packard Industrial Printing LTD.Inventors: Semion Gengrinovich, Liad Weissman, Lev Superfin

Patent number: 9643406Abstract: In some examples, a system includes a printhead including a printer fluid nozzle, an air valve in fluid communication with a channel of the nozzle to: (1) create back pressure in the channel when the air valve is closed and printer fluid is ejected through the nozzle and (2) release back pressure in the channel when the air valve is open, an ejector to eject printer fluid through the nozzle to form a meniscus of printer fluid in the channel when the air valve is closed, a pressure sensor to measure pressure within the channel, and an indicator in electrical communication with the pressure sensor. The indicator can, for example, indicate whether there is an air leak in the channel by determining whether the pressure in the channel is within a predetermined pressure range after a predetermined idle time following the formation of the meniscus in the nozzle.Type: GrantFiled: February 25, 2016Date of Patent: May 9, 2017Assignee: Hewlett-Packard Industrial Printing LTD.Inventors: Semion Gengrinovich, Ran Vilk, Moti Balaish

Patent number: 9573377Abstract: An apparatus includes a tank for holding a fluid for delivery to a printhead, the tank being open to the atmosphere. A manifold enables the fluid to flow from the tank to the printhead, a height of the manifold being lower than a level of the fluid in the tank when the fluid is flowing from the tank to the printhead. A siphon has a lower end of the siphon that is connectable to the manifold. An upper end of the siphon extends above the level of the fluid and is openable to the atmosphere. A height of a segment of the siphon between the upper end and the lower end is lower than the height of the manifold.Type: GrantFiled: July 13, 2012Date of Patent: February 21, 2017Assignee: Hewlett-Packard Industrial Printing LTD.Inventors: Semion Gengrinovich, Ran Vilk, Lev Superfin

Patent number: 9156255Abstract: In one embodiment, an actuator connected to a printhead structure is activated with a waveform to cause vibration of the structure sufficient to move fluid within a printhead channel adjacent to the structure and not cause the fluid to eject from the channel during a nonprinting period. In another embodiment, a first pulse module applies a pulse at a printhead structure at a combination of voltage, duration, and frequency to cause shaking of printhead structure to move fluid within a printhead channel adjacent to the structure without ejecting the fluid from the channel during a nonprinting period. In another embodiment, an actuator connected to a printhead structure is activated during a nonprinting period to pulse the structure to move fluid within a printhead channel adjacent to the structure without causing the fluid to be expelled from the channel.Type: GrantFiled: December 22, 2011Date of Patent: October 13, 2015Assignee: Hewlett-Packard Industrial Printing LTD.Inventors: Semion Gengrinovich, Dennis Indorsky, Ran Vilk, Lev Superfin
