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: 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

Patent number: 8376507Abstract: In one embodiment, a non-contact print head cleaning device includes an elongated cavity underlying a print head and a vacuum port connected to the elongated cavity and generating a low pressure in the elongated cavity. A slot in a wall of the elongated cavity has a geometry that varies along its length to produce an airflow with a substantially uniform velocity into the slot. The airflow sucks contaminants off the print head into the slot. A method for non-contact print head cleaning is also provided.Type: GrantFiled: March 10, 2011Date of Patent: February 19, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Edgar Friedmann, Lev Superfin, Semion Gengrinovich
