An Image on the Back of Your Original Appears in Your Scanned Image
If your original is printed on thin paper, images on the back may be visible to the scanner and appear in your scanned
image. Try scanning the original with a piece of black paper placed on the back of it. Also make sure the Document
Type and Image Type settings are correct for your original. See
