Jon get a piece of 8.5x11 cardstock white paper and insert it into the documents port. It doesn't insert like a receipt you have to push it down into the scanner until it stops. At this point run the calibration then the clean cycle about 5 times and this will fix the problem. I had the same problems and once I figured out how to calibrate and clean it properly it works like a charm. I wasn't even getting an image after a scan I was also getting the grey band sometimes but this fixed it for me....good luck.
