How do I scan a document larger than A4 or Letter size, such as an A3 document?

Use the Folio Scan function to scan documents larger than LTR/A4, up to a maximum size of 11" x 17"/A3. Fold the document in half lengthwise, crease it firmly, and place it in the feeder with the folded edge facing right under default settings. The scanner will scan both sides and combine them into a single image, though a small portion of the image at the fold line will be missing. (Page 31-32)
