Publication number: 20230373222Abstract: Examples in accordance with the present disclosure are directed to a method including generating a negative fluid pressure between a fluid supply and a first port of a fluidic ejection device, and generating a positive fluid pressure between the fluid supply and a second port of the fluidic ejection device. The method further includes selectively activating a first priming pump connected to the first port in response to an indication that the first port is transitioning from an open state to a closed state, wherein the selective activation of the first priming pump causes the first port to remain in the open state and causes fluid within the fluidic ejection device to exit through the first port and to recirculate along a fluid flow path.Type: ApplicationFiled: October 15, 2020Publication date: November 23, 2023Inventors: Mauricio SERAS FRANZOSO, Dorkaitz Alain VAZQUEZ FERNANDEZ, David BUTINYA TEIXIDO

Patent number: 11214068Abstract: There is provided a maintenance apparatus to, while in a service zone, perform a cleaning operation of a set of printheads within a carriage. The maintenance apparatus comprises a cleaning structure and an actuation mechanism. The actuation mechanism is arranged to position the cleaning structure between an engaged configuration and a disengaged configuration. The disengaged configuration is activated by a first triggering element associated to the carriage interacting with the actuation mechanism subsequent to a cleaning operation. The engaged configuration is activated by a second triggering element as the carriage moves away from the service zone.Type: GrantFiled: April 30, 2018Date of Patent: January 4, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Sheila Cabello Cabrera, Mauricio Seras Franzoso, Andreu Cortes Vicens

Patent number: 10688817Abstract: Examples associated with printer configuration are disclosed. One example includes printing, using a printer, a first portion of a test patch in a first print direction. A second portion of the test patch is printed in a second print direction. The second portion is printed at a first offset from the first portion. A first portion of a second test patch is printed in the first print direction, and a second portion of the second test patch is printed in the second print direction at a second offset from the first portion of the second test patch. The printer is configured to print in the second print direction using one of the first offset and the second offset based on a selection between the first test patch and the second test patch.Type: GrantFiled: July 9, 2015Date of Patent: June 23, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Joan Albert Jorba Closa, Lluis Hierro Domenech, Mauricio Seras Franzoso

Patent number: 10525703Abstract: Herein is described a method involving a drop detector. The method may comprise: ejecting ink drops from the nozzles on a printhead toward a drop detector. A drop characteristic may then be determined from the drop detector for each ink-jet nozzle. Drop characteristics for the nozzles across the printhead may be collated into a data set, and compared with a predetermined data set for a printhead having predetermined print behaviour to determine if and how the data sets differ in terms of the pattern of drop characteristics across the printheads. If the data sets differ, a recovery strategy may be selected based how the data sets differ in terms of the pattern of drop characteristics across the printheads. A system and computer readable medium are also described herein.Type: GrantFiled: October 23, 2015Date of Patent: January 7, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Antonio Gracia Verdugo, Mauricio Seras Franzoso, Joan Jorba Closa
