Patent number: 8057010Abstract: A method of printing an image on a substrate using a page-wide-array printer and a page wide array printer is provided. The method includes printing a first portion of the image as relative movement occurs between the substrate and the print heads, and printing a second portion of the image as relative movement occurs between the substrate and the print heads, such that there exists an area of overlap between the first portion of the image and the second portion of the image. The substrate may be moved in a first direction relative to the print heads whilst the first portion of the image is printed, moved in a second direction opposite to the first direction; and moved in the first direction again whilst the second portion of the image is printed. The substrate may be printed whilst the substrate is moved in the second direction.Type: GrantFiled: September 29, 2008Date of Patent: November 15, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Sergio Puigardeu, Alex Andrea, David Gaston, Joan Joroa, Angel Martinez, Silvia Miramanda, Ramon Vega, Jordi Sender, Marti Rius

Patent number: 7866779Abstract: Printing is performed at a full resolution using a first set of nozzles and a second set of nozzles arranged on a printhead. Printing is performed at less than the full resolution using the first set of nozzles less any nozzles in the first set of nozzles that have been determined to be defective. The second set of nozzles is not used for printing at less than the full resolution except for a subset of nozzles in the second set of nozzles that are used to replace nozzles from the first set of nozzles that have been determined to be defective.Type: GrantFiled: October 1, 2008Date of Patent: January 11, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Angel Martinez, Alex Andrea, David Gaston, Joan Jorba, Silvia Miramanda, Sergio Puigardeu, Marti Rius, Jordi Sender, Ramon Vega

Patent number: 7431417Abstract: A printer is configured to manage a signal-to-noise ratio of a signal produced by a sensor scanning a print test pattern. The print test pattern is printed while controlling ink density printed by each of one or more pens. Each ink density is selected so that the signal-to-noise ratio exceeds a threshold as the print test pattern is scanned. Pens within the printer are aligned or otherwise maintained by adjusting nozzle firings as indicated by data obtained from the signal during the scanning.Type: GrantFiled: October 27, 2004Date of Patent: October 7, 2008Assignee: Hewlett-Packard Development Company, L.P.Inventors: Josep Antoni Rodenas, Marc Serra, David Gaston

Patent number: 6910754Abstract: By implementation of an optical scanner, the calibration of printheads of a printing mechanism may be performed in a relatively short period of time as compared to known techniques. In one respect, the time required to perform the calibration may be substantially reduced by virtue of the relatively wide field of view of the optical scanner. The relatively wide field of view generally enables for the scanning of test patterns to be performed with a relatively fewer number of scanning passes, thus reducing the time required to perform the scanning operations as well as the calibration operations. In addition, the scanning operations may yield relatively more accurate results as compared to known scanning operations. In one respect, optical scanners are capable of detecting smaller drops of ink on print media by virtue of their higher resolution capabilities.Type: GrantFiled: October 29, 2003Date of Patent: June 28, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: David Gaston, Francesc Subirada, Xavier Soler
