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. The system may also
include a diagnostic subsystem for determining causes for a detected
banding defect to further enhance the operation of the compensation
system or to facilitate a repair action by a person.
