- Avoiding damage on Mustek flatbed scanners
        Most Mustek flatbed scanners have no protection against exceeding
        the physical scan area height.  That is, if a scan is attempted with
        a height that exceeds the height of the scan surface, the scanner
        begins making loud noises and the scan mechanism may be damaged.
        Thus, if you hear such a noise, IMMEDIATELY turn off the scanner.

I once had a  scanner (neither Mustek nor Agfa) damaged because of this. Don't 
know about your case, but I would be most carefull.
