Epson Expression 10000XL- Graphic Arts Scanner

The “B-size” and “A3+” specifications refer to the largest standard document size that you can fit on the scanner’s document table. A B-size document measures 11” x 17”, while an A3+ document measures 11.7” x 16.5”. Since the maximum scanable area for the Expression 10000XL is slightly larger (12.2” x 17.2”), the scanner is described as an A3+ or B-size scanner.
