Patent number: 10207499Abstract: Examples associated with drop velocity aberrancy detection are disclosed. One example includes firing ink through nozzles of a print-head past sensors to identify drop velocities of the nozzles. A target drop velocity is selected based on the drop velocities of the nozzles. An aberrant nozzles is detected when a nozzle has a drop velocity that deviates from the target drop velocity by a selected threshold. The aberrant nozzle is deactivated, and a good nozzle that will travel over locations traversed by the aberrant nozzle is configured to print portions of a job that would have been printed by the aberrant nozzle.Type: GrantFiled: February 27, 2015Date of Patent: February 19, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Mauricio Seras Franzoso, Antonio Gracia Verdugo, Marta Coma Vives

Publication number: 20180222182Abstract: 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: ApplicationFiled: October 23, 2015Publication date: August 9, 2018Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Antonio Gracia Verdugo, Mauricio Seras Franzoso, Joan Jorba Closa

Patent number: 10035343Abstract: In some examples, a method includes, in response to a fluid firing unit being operated according to a normal printing mode, applying a first voltage to the fluid firing unit to fire the fluid firing unit during a printing operation. The method further includes determining, using a sensor, whether a predetermined condition is met, and in response to determining that the predetermined condition is met, operating the fluid firing unit according to a recovery mode in which a second voltage higher than the first voltage is applied to the fluid firing unit to clean the fluid firing unit.Type: GrantFiled: June 6, 2017Date of Patent: July 31, 2018Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ana Cristina Garcia Alvarez, Antonio Gracia Verdugo, Mauricio Seras Franzoso

Patent number: 9994025Abstract: A cleaning module includes an actuator device, a fluid chamber, and a wiper member. The actuator device may enter an activation state based on a movement of at least a portion of the actuator device in response to an engagement with the printhead. The fluid chamber may store and supply fluid to the porous wipe material in response to the activation state of the actuator device. The wiper member may apply pressure to a porous wipe material including the fluid therein to wipe the printhead.Type: GrantFiled: March 3, 2017Date of Patent: June 12, 2018Assignee: Hewlett-Packard Development Company, L.P.Inventors: Mauricio Seras Franzoso, Marta Coma Vives, Antonio Gracia Verdugo

Publication number: 20180154663Abstract: 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: ApplicationFiled: July 9, 2015Publication date: June 7, 2018Applicant: Hewlett-Packard Development Company, L.P.Inventors: Joan Albert JORBA CLOSA, Lluis HIERRO DOMENECH, Mauricio SERAS FRANZOSO

Patent number: 9770899Abstract: A method for controlling the amount of printing fluid deposited by a printhead for a plurality of passes of a swath width of a printing process is described. The printing process may include periodic servicing of the printhead. The method may include determining an amount of printing fluid to be deposited for each pass of the swath width; identifying which pass of the swath width servicing is to occur; and reducing the determined amount of printing fluid deposited during a first pass immediately following servicing of the printhead.Type: GrantFiled: October 14, 2013Date of Patent: September 26, 2017Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Mauricio Seras Franzoso, Marina Cantero Lazaro, Antonio Gracia Verdugo
