Everything runs fast, scans look great, except one issue. When scanning sportscards on one side, there is a very noticeable line (almost like a light spot) running down the middle. If I turn the card over and scan duplex, it comes out clean, as the top (door) scanner element is used. It appears it only happens if the lower scanner is being utilized, if that makes sense.
I've tried all the recommended cleaning, taking out rollers and cleaning, etc;
Having big marks all the way down the scans is a death sentence in the sportscard world and it makes it unusable until I solve.
Thank you for any assistance!
