Patent ID: 7400339

Claim:
A system for adjusting operation of an image reproduction system to compensate for banding defects comprising: a detection subsystem coupled to one of a charging subsystem, an exposure subsystem, a development subsystem, a transfer subsystem, and a fusing subsystem of an image reproduction system for monitoring the coupled subsystem for detection of a banding defect; an automated compensation subsystem having an input data compensation subsystem coupled to a digital front end/image input terminal (DFE/IIT) of the image reproduction system to modify preprocessing of image data performed by the DFE/IIT to compensate for a detected banding defect, the automated compensation subsystem also being configured for modifying operation of the image reproduction system by adjusting one or more subsystems other than the subsystem being monitored by the detection subsystem to compensate for the detected banding defect so that the image reproduction system continues to generate images at an acceptable quality level; and a diagnostic subsystem coupled to the detection subsystem to receive error identification data from the detection subsystem, the diagnostic subsystem being configured to identify a subsystem causing the detected banding error corresponding to the error identification data; and the automated compensation subsystem further comprising a local compensation subsystem that is coupled to the diagnostic subsystem, the local compensation subsystem being configured to modify operation of the subsystem identified by the diagnostic subsystem as being a cause of the detected banding defect.
