1. A method for scanning an original in an image-processing device wherein the original comprises a first page and a second page with both the first and second pages disposed face-down on an included platen, comprising: (a) scan the platen; (b) form a platen image based on scanning the platen; (c) determine the position of a first original corner with respect to an included fixed platen reference point, thus forming a corresponding first set of original corner platen coordinates and determine the position of a second original corner with respect to the fixed platen reference point, thus forming a corresponding second set of original corner platen coordinates, wherein the first original corner is diagonally opposite the second original corner; (d) form an original image based on the platen image, the first set of original corner platen coordinates and the second set of original corner platen coordinates; (e) determine the size and position of the first page and the size and position of the second page based on the first set of original corner platen coordinates and the second set of original corner platen coordinates; (f) form an image of the first page based on the original image and the size and position of the first page, thus forming a first image; and (g) form an image of the second page based on the original image and the size and position of the second page, thus forming a second image.
