<p>I occasionally have linear vertical banding that is perfectly straight when scanning 6 x6 negatives on my Epson V500; the streaks continue throughout the scanned negatives. During "Preview" scan with Vuescan, it could be seen beginning before the sensor got to the negative area. It occurred with either Epson's scanning program or Vuescan, and cleaning the glass surfaces made no difference. Reinstalling driver made no difference. Negatives were without visual evidence of scratches or other defects. I scan strips of 4 negatives, so that means 2 are not in the scanning area of the negative holder; the unscanned negatives <strong>should</strong> be towards the front of the scanner, as there is a small cutout at the back of the negative holder that I guess is used for sensor calibration. Turns out when I inadverdently left that area covered with negative--when I had the strip sticking out of the holder the <strong>wrong</strong> way-- the vertical bands would appear. Reorienting the film fixed the problem for me. Such a simple cause, but so much frustration.</p>
