Scan the pages and open them in Photoshop. In Photoshop, choose "Select" from the top menu, then "Color Range". Use the eyedropper to sample the gray color, then adjust the "Fuzziness" slider to narrow the selection to the gray color (I set it to '17' on the screen capture I took of your sample). Hit "OK", then the "Delete" button on your keyboard. Should be left with only the dark black left on a white background.
Good luck!
Ah, clever.
