A control unit controls the presence or the absence of the minute vibrations to be applied to the pressure chamber at the print period, and causes the respective unit ejection portions to execute the flushing operation so that an ejection quantity of ink by the flushing operation of the unit ejection portion, to which the minute vibrations is applied at the print period, exceeds the ejection quantity of ink by the flushing operation of the unit ejection portion to which the minute vibrations are not applied at the print period. | 2012-04-05 |
| 20120081435 | METHOD OF COMPENSATING FOR DEAD NOZZLES IN STATIONARY PAGEWIDTH PRINTHEAD - A method of compensating for a dead nozzle in a stationary pagewidth printhead. The method includes the steps of: (i) identifying the dead nozzle; (ii) selecting a functioning nozzle in a same nozzle row as the dead nozzle; and firing ink droplets from the selected functioning nozzle at a primary dot position associated with the dead nozzle. | 2012-04-05 |
| 20120081436 | IMAGE PROCESSOR AND IMAGE PROCESSING METHOD - When printing an image using a plurality of inks, color unevenness caused by variations in ejection characteristics among nozzles is corrected at suitable timings in accordance with change in the color unevenness over time, and favorable image output without noticeably color unevenness is maintained. For this purpose, parameters are prepared, for colors formed by combinations of at least two colors of ink, the parameters being determined so as to reduce differences in coloration on a print medium caused by individual variations in the ejection characteristics of a plurality of nozzles. When printing, a first color signal included in individual pixels is corrected for a second color signal by using the parameters. Information regarding the ejection volume characteristics of a plurality of nozzles is acquired as appropriate, and by estimating changes in coloration from this information, suitable timings for overwriting such parameters are determined. | 2012-04-05 |
| 20120081437 | LIQUID EJECTING DEVICE - A liquid ejecting device to eject droplets of liquid onto a recording medium is provided. The image ejecting device includes a recording medium conveyer, a liquid ejecting head, a detector unit, an image data storage, a controller, and a cancellation signal output unit to output cancellation signals in an error condition.

| 20120081439 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, INKJET PRINTING APPARATUS, AND INKJET PRINTING METHOD - The invention decreases the enlargement of memory and processing time for the correction of image data carried out to reduce image deterioration caused by nozzle ejection characteristic variation in an inkjet printing apparatus. Print heads are provided with pluralities of chips that have nozzle arrays formed from a plurality of nozzles. Coupled portions and non-overlap portions are formed on each chip. An image processing apparatus sets input image data, which correspond to nozzle regions that are defined in nozzle arrays along the alignment direction of the nozzles of the print head and that are composed of a plurality of nozzles, as processing blocks. The input image data is processed according to parameters defined for each of those processing blocks. The boundaries of the nozzle regions corresponding to the input image data of the processing blocks are established according to the boundaries of the overlap portions and the non-overlap portions. | 2012-04-05 |
| 20120081440 | DROP VOLUME COMPENSATION FOR INK SUPPLY VARIATION - The present invention relates to a method that enables image quality of a printed image to be maintained by reducing unintended variations in drop volume, through the adjustment of ink drop ejecting conditions depending on the amount of ink remaining in an ink tank chamber or reservoir, and/or the ink demand for printing an image. The method of printing of the present invention comprises: providing a printhead in fluid communication with an ink chamber or reservoir; detecting at least one parameter related to an amount of negative pressure provided to the printhead; and adjusting an ink drop ejecting condition of the printhead as a function of the parameter so that an amount of variation in size of ejected ink drop is reduced. | 2012-04-05 |
