| 20090002429 | PRINTER CALIBRATION - A printer and method of calibrating such a printer is presented. The method comprises: printing a reference pattern on print media; depositing ink over the printed reference pattern; printing a test pattern over the deposited ink to form an interference pattern; and determining an ink density value that results in an acceptable deformation of the printing media based on an optical evaluation of the interference pattern. | 01-01-2009 |
| 20090128593 | PRINTERS AND PRINTHEAD CLEANING PRIMARILY IN PAGE-WIDE ARRAY PRINTERS - A method of printing on a substrate and a printer are provided. The method uses a printer comprising a print head and a mask having a hole therethrough, the mask being disposed between the print head and the substrate, and comprises aligning the hole with the print head; printing on the substrate through the hole; and misaligning the hole with the print head so that the print head is covered by the mask. The method may allow the servicing of a print head in the array while the printer is printing on the substrate using at least one of the remainder of the print heads in the array. | 05-21-2009 |
| 20090128594 | DEFECTIVE NOZZLE REPLACEMENT IN A PRINTER - 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. T he 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. | 05-21-2009 |
| 20090135217 | SELECTING PRINTING MASKS OPTIMIZED FOR LINE FEATURES AND AREA FILL FEATURES OF IMAGE DATA - For each totally black pixel of image data to be printed using a fluid-ejection printing device, it is determined whether the pixel is part of a line feature or an area fill feature of the image data. Where the pixel is part of a line feature, a first printing mask selected that is optimized for printing line features. Where the pixel is part of an area fill feature, a second printing mask is selected that is optimized for printing area fill features. Each mask specifies a number of fluid droplets to be printed and positions where the fluid droplets are to be printed. The selected mask is applied to the pixel. The pixel is printed using the mask that has been applied. The fluid-ejection printing device prints the pixel by ejecting the number of fluid droplets specified by the mask at the positions specified by the mask. | 05-28-2009 |
| 20090237443 | PRINT HEAD SERVICING FOR A PAGE WIDE ARRAY PRINTER - A page wide array printer comprises a print head bar which carries an array of print nozzles, and which is static during a printing operation. A carriage has print head service elements. The print head bar is movable perpendicularly to the plane of the print medium beneath the print head, between a lowered print position and a raised service position. The carriage is moveable along the print head to perform a service operation when the print head is in the raised position. | 09-24-2009 |
| 20090262380 | CONCURRENT IMAGE AND DIAGNOSTIC PATTERN PRINTING - Print image-quality defects are diagnosed by printing an image and one or more diagnostic patterns concurrently. | 10-22-2009 |
| 20090303514 | AUTOMATIC ARRANGEMENT OF NESTED IMAGES AS A FUNCTION OF ASSIGNED PRINT MODES - Images selected for printing are assigned respective print-speed modes so that at least first and second of said images are assigned to a relatively fast print mode and at least a third image is assigned to a relatively slow print mode. The images are arranged as a function of print-speed mode so that said first and second images are in a first row and so that said third is in a second row. The images are then printed on real print media, with the first row being printed using a relatively fast print speed and the second row being printed at a relatively slow print speed. | 12-10-2009 |
| 20090320333 | TOOTH AND ADAPTOR FOR DREDGING MACHINE - The tooth and adaptor for dredging machines object of the present invention relates to a tooth or wear member which, attached to an adaptor or adaptor member, creates an assembly the purpose of which is to deepen and clean the beds of ports, rivers, channels, etc., removing therefrom sludge, stones, sand, etc., the adaptors being attached to the blades of the propellers and thus forming the cutter head of the dredging machine. The constructive features of the coupling between the tooth and the tooth bar or adaptor allow making better use of the cutting material of the tooth and a simple and quick replacement thereof in the adaptor, between other advantages. | 12-31-2009 |
| 20100026744 | Printhead Diagnostic Plot - Among various embodiments of the present disclosure, systems and methods for diagnosing printhead status are shown. The printhead status can be diagnosed by detecting which of a number of nozzles in a first printhead fire ink; and printing with visible ink a diagnostic plot using a second printhead that maps which nozzles fire ink in the first printhead. The number of nozzles in the first printhead which fire ink is determined by visually identifying the nozzles that fire ink in the second printhead as indicated by the placement of the visible ink on the diagnostic plot. | 02-04-2010 |
| 20100115804 | DETACHABLE FASTENING SYSTEM BETWEEN A MALE PIECE AND A FEMALE PIECE, PIN AND FEMALE PIECE - Detachable fastening system between a male piece ( | 05-13-2010 |
| 20100220130 | AVOIDING PRINTHEAD CONTACT - A system for avoiding printhead contact is disclosed. In one embodiment, the system includes a detector switch configured to detect printhead contact, and a processor that is coupled to the detector switch and is configured to initiate action to avoid printhead contact. | 09-02-2010 |
| 20100277525 | METHOD OF PRINTING AND PRINTER - A method of printing on a substrate in a page-wide array printer comprises printing on the substrate as the substrate is moved through a printing zone of the printer in a first direction, and printing on the substrate as the substrate is moved through the printing zone in a second direction different to the first direction. | 11-04-2010 |
| 20110116109 | Restricting Printing - In one embodiment, an option to restrict printing to a first print media source is presented to a user of a printer that is configured to access a plurality of print media sources. An instruction to restrict printing to the first print media source is received from the user. The printer is restricted from printing to the first print media source. | 05-19-2011 |
