摘要： 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. In another respect, all of the printed colors may be accurately detected through implementation of a red, green, blue (RGB) charge coupled device (CCD) contained in the optical scanners.

摘要： A multicolor-printer has at least a first and a second print station, first and second optical sensors and a surface recordings comparator. The first and second print stations are arranged to print images on a surface of a moving recording medium. The first and second optical sensors view, at the first and second print stations, an area of the recording medium surface to obtain at least one first surface recording, in a manner related to the first print station's image printing, and second surface recordings, respectively. A storage is arranged to store the first surface recording. The surface recordings comparator is arranged to test, during the recording medium movement, for correspondence of second surface recordings with the stored first surface recording. The printer is arranged to repeatedly, within one image, register raster lines of the image of the second print station to corresponding raster lines of the image of the first print station in response to correspondences found between the first and second surface recordings.

摘要： Techniques for calibrating a scanner mounted on a scanning carriage of an image forming device. In one embodiment, a method of calibrating an optical sensor of a color image forming device includes positioning a prefabricated optical sensor target at the service area of the image forming device, the target including a plurality of target patches of predetermined different colors, moving the carriage to the service area, acquiring one or more images of the plurality of target patches, and using the one or more images to perform a plurality of calibrations of the optical sensor. In another embodiment, a method of measuring a reference position of a carriage mounted sensor array for an image forming device includes moving the carriage to a service area, generating a light beam from a carriage-mounted light source at a position adjacent an end of a sensor array, the light beam at an acute angle relative to an array axis, reflecting the beam from a reference target mounted in the service area at a known position, acquiring an image of the reflected beam by the sensor array, and using the location of a high intensity area of the image to determine the reference position of the optical sensor.

摘要： A test pattern is scanned to find ideal print-medium advance for a pen (or other marking device). The pattern has a medium; and, marked on it, image patches each with overlapped swaths stepped by different distances. At best there are different-color pens; and for each distance a set of patches, each with a patch for each color (preferably area fills at sensitive tones by color). All patches in a set are best adjacent along a scan direction, with alignment lines above each set across the whole pattern, and a nozzle-conditioning patch at each image patch. A processor prints the pattern, operates a sensor and uses its signals to find optimum advance. The system finds and prints with ideal advance for a most-active pen; or weighs pen activity to find an optimum for all pens based on certain statistical and/or prospective choices.

摘要： A media-positioning sensor assembly in one embodiment of the invention is disclosed that includes a mechanism and a media-positioning sensor. The mechanism moves back and forth over media along a first axis. The media advances past the mechanism along a second axis perpendicular to the first axis. The media-positioning sensor is situated on the mechanism and is to detect positioning of the media relative to the mechanism along at least one of the first axis and the second axis.

摘要： 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.

摘要： A method and apparatus is used to detect and compensate for printhead rotation in an inkjet printer. The detecting operation includes receiving an initial image of a pattern taken from a medium as the printhead passes over the medium, receiving a subsequent image of the pattern taken from the medium as the printhead continues to pass over the medium, comparing the initial image of the pattern and the subsequent image of the pattern taken from the medium and identifying a rotation of the printhead in the ink-jet printer passing over the medium if the comparison indicates the initial image of the pattern is rotated relative to the subsequent image of the pattern. The compensation operation includes modifying the timing settings associated with the firing of the nozzles in the inkjet printhead to compensate for the rotation of the printhead.
