I have a very small handful of medium format color negatives I want to scan, so I pulled out my old Epson 1200U Photo flatbed scanner. Yes, I know it's ancient. Yes, I know flatbed scanners aren't ideal for film. Yes, I know I should buy a newer scanner. But since I'm just doing a handful of negs and only need the images for the web, I'm happy using this for the moment. The problem is that when I use the film adaptor and scan a negative I get a very thin dark blue line that runs across the image. The position of the line is fixed, running roughly down the middle of the long distance of the flatbed. That puts it running across the middle of a 2 1/4 negative in the film holder when using the film adaptor. It's definitely something electronic, not a scratch on the film, since I have the same problem with multiple negs from multiple shoots from multiple cameras over a period of years. The line appears in a fixed place n relation to the glass on the scanner -- rotating the film holder only makes it show up on a different place in the image. Doesn't seem to be a mark on the glass since it doesn't show up when I scan prints. I've tried jiggling the cord that connects the film adaptor to the scanner in the hope it was just a lose connection even tried jiggling the USB cord. Tried with different computers and same problem. Tried with VueScan in addition to the Epson software and I get the same problem. Any thoughts?
