For years I have used an Epson V700 to scan 4x5 negatives in one pass with no issue. Now it has suddenly and inexplicably started slicing the image into three vertical strips that have to be stitched together. I didn't change any settings and haven't installed any updates. I have tried rebooting everything, resetting Epson scan, and uninstalling and reinstalling both the scanner drivers and Epson Scan, several times. I can't find any sign online of anyone else ever having experienced this.

Has anyone seen this happen, and if so how did you fix it?
