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: 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
