Abstract: A technique for assessing nozzle health of a printhead nozzle array in a printing system includes printing a swath portion of an image, optically scanning the printed swath portion to capture a scanned image, comparing an expected image of the swath portion of the image with the scanned image, and assessing whether any nozzles of the nozzle array have malfunctioned. A sensor can be mounted on a printhead carriage to accomplish the image capture.

Abstract: The present invention is directed to a method and apparatus for testing the operational status of printhead nozzles. High throughput drop detection devices are used to detected ink drops that are fired from the printhead nozzles, and the operational status is determined from the ink drop characteristics. The ink drop characteristics may include the presence or absence of an ink drop. Ink drop characteristics may also include the size and the location of an ink drop. The drop detection devices are capable of detecting a plurality of ink drops that are ejected substantially simultaneously.

Abstract: An optical sensor for detecting the position of marks on a medium, wherein relative motion is provided between the optical sensor and the medium during an optical sensing operation. The optical sensor produces an electrical sensor signal, and has a field of view at the media in a direction of the relative movement. The marks have a nominal dimension in the direction of the relative movement, and the field of view is larger than the nominal dimension. This produces a sensor signal with a clear and relatively sharp peak in response to scanning the media mark. A method of sensing directional aberrations among ink-jet nozzles of a plurality of printheads mounted on a scanning carriage is described, which includes printing an alignment pattern on a print medium, the alignment pattern comprising a set of target marks printed using a subset of the nozzles on each of the plurality of printheads, and a set of monochrome marks printed using a subset of the nozzles from only one of the printheads, each of the monochrome marks positioned in a nominal position with respect to a corresponding plurality of the target marks, and optically scanning the alignment pattern to determine measurements of relative positions between the monochrome marks and corresponding target marks. In one embodiment, the target marks include an elongated first mark disposed in a scan direction of scanning movement of the scanning carriage, and an elongated second mark disposed in a media moving direction transverse to the scan direction. In another embodiment, the target marks are patches of similar size to the monochrome marks.

Abstract: When condition of a printing element (e.g. inkjet nozzle) changes, essentially full mask rows invoking the element are redone from scratch, best so as to fully satisfy pixel-grid neighbor conditions. This is faster than redoing a whole mask as in prior popup or precook /reheat methods, and yields better printouts than prior row-by-row mask revision (e.g. directly replacing a weak nozzle by a good one across whole rows). This method is best independent of prior mask versions, and uses no prebuilt matrix of backup/alternate entries. The number of rows redone is typically 7% to 14% below a nominal/baseline value.
