After upgrading from Sierra to High Sierra it seems that when I scan a document in Preview v.10.0 (944.5) with a usually reliable Epson 2450 Photo Scanner the image sometimes is blurred. I have the same problem using Image Capture v.7.0 (1106). I also see that many saved scans are also blurred in Finder but I found that if I open the file and then I use "Display at actual size" the scan is resized and then is in focus. Is there a fix? Thank you.
