I have a mustek A3 1200S and all scans come up with the left side of the page darkened (if its a greyscale scan) or discolored (if its a color scan). I have tried re-installing the scanner and running a re-calibration utility from the mustek site. Is it likely to be the light source failing? Any help is appreciated.
