  • System and method for evaluating and correcting image quality in an image generating device
    Patent number: 8469485
    Abstract: A system evaluates image quality in an image generating system. The system includes a test pattern generator configured to generate an image with an image generating system, an image capture device configured to generate a digital signal corresponding to the generated test pattern, an image evaluator configured to process the digital signal to detect and correct anomalies detected in the generated test pattern, a plurality of calibration tools, each calibration tool being comprised of at least one test pattern, at least one set of detection criteria, and at least one set of anomaly correction parameters, and a controller configured to select the calibration tools for operation of the test pattern generator and the image evaluator in accordance with a predetermined sequence that attenuates changes arising from application of correction parameters of one calibration tool upon a later selected calibration tool.

  • System and method for scheduling ink jet recovery in an ink jet printer
    Patent number: 8162433
    Abstract: A method enables an ink jet image generating system to select an operational mode in response to detection of a missing ink jet. The method includes generating a digital image of an ink image on an image receiving member of an ink jet image generating system, detecting missing inkjets in a printhead of an ink jet image generating system from the digital image of the ink image on the image receiving member, and selecting an operational mode for the ink jet image generating system in response to the detection of at least one missing ink jet.
