Claim One:
1. A method for controlling an imaging system, comprising: forming a test pattern image on an image receiving media substrate, the test pattern image consisting of at least two laterally-displaced test areas, at least a first test area being a plain white test area and at least a second test area being a dark test area; first scanning the test pattern image formed on the image receiving media substrate with a scanning device, the image receiving media substrate being exposed to the scanning device in a first physical orientation; storing first information from the first scanning in a memory; physically reorienting the image receiving media substrate with the test pattern formed thereon to a second physical orientation that is different from the first physical orientation; second scanning the test pattern image formed on the image receiving media substrate with the scanning device, the image receiving media substrate being exposed to the scanning device in the second physical orientation; storing second information from the second scanning in the memory; and comparing, with a processor, the first stored information from the first scanning and the second stored information from the second scanning to isolate at least one image quality defect in the twice scanned test pattern image.
