  • Method and system for automatically compensating for diagnosed banding defects prior to the performance of remedial service
    Patent number: 7400339
    Abstract: A system that extends the operational effectiveness of an image reproduction machine without requiring downtime for service by personnel includes a detection subsystem that monitors components of an image reproduction system for detecting a banding defect in the image reproduction system and an automated compensation subsystem for modifying operation of the image reproduction system to compensate for the detected banding defect so that the image reproduction system continues to generate images at an acceptable quality level. The automated compensation subsystem adjusts components and/or data used by image reproduction system to compensate for the identified banding defect without requiring immediate operator or service personnel intervention. This compensation may successfully attenuate the banding defect so that the image reproduction system continues to produce acceptable images without downtime while awaiting service by personnel.

  • Methods and systems achieving print uniformity using reduced memory or computational requirements
    Publication number: 20060077488
    Abstract: Engine response curves (RCs) can be used for streak compensation for printed documents. A feedback control paradigm can be included to effect RC compensation. Singular Value Decomposition (SVD) can be used to represent each RC in the collection of spatial RC data as a linear combination of basis vectors. RCs are approximated by selecting the first few basis vectors, the approximation aiding in noise rejection and reducing computation in the controller by reducing dimensionality of the RC data from gray levels to the number of SVD bases selected. An optimal subset of RCs is selectable from the set of approximated RCs by clustering the SVD weights, the clustered SVD weights producing TRCs that span all engine response RCs generated by a printer.
