  • Patent number: 8208183
    Abstract: Systems and methods for implementing use of customer documents in maintaining image quality or image quality consistency of printing devices are provided. The system may include a marking engine constructed to print images on an image bearing surface of the print device; one or more color measuring devices for measured toner images formed on the image bearing surface corresponding to the one or more relevant pages, and an image analyzer configured to generate reference images and to compare measured image data with the reference images. The image analyzer may also be configured to analyze input image data for a document and to identify one or more relevant pages of the document that may provide information regarding the state of the printing system to generated reference image data. Comparisons between the color separations of the reference image data and measured image data images may be realized for determining defects.

  • Patent number: 8150106
    Abstract: A method for automated image quality based diagnosis of a document printing system is disclosed. The method comprises receiving image data to be printed on a document; printing an image on the document based on the image data; scanning the printed image on the document with a sensor; analyzing the scanned printed image with an image quality analysis module to identify one or more defects in the printed image; automatically generating test pattern image data based on the one or more identified defects; and printing and analyzing a test pattern image based on the test pattern image data.
