ABSTRACT:
A method for monitoring and adjusting the calibration for an image processing apparatus entails imaging a calibration target to create an image using the image processing apparatus and scanning the image into host software to create an exposure calibration curve. Control strips are imaged to create control strip images on order to obtain a calibrated density history for the control strips using the control strip images. The control strip images are scanned into the host software to obtain a scanned density history for each control strip and thereby form a density history for the control strips. A deviation history is calculated by comparing the scanned density history to the calibrated density history for each control strip. The deviation history is monitored to ensure that the deviation history is within the operating specifications for the image processing apparatus.
