I'm new to this forum. I recently inherited a Nikon Super Cool Scan 4000 ED and I'm using it to scan my old B&W negatives. I've got it up and running with VueScan. But the first scan I did has a lighter area going down the middle of a portrait scan. I tried another neg, got the same streak, actually it's most of the image except for the edges on each vertical side. I've gone over the input and ouput settings several times, but I can't make the light streak disappear. Has anyone else encountered this problem?
