You'll probably find it's broken. Theyre very very expensive machines to buy, maintain (and repair) but have been supersceeded by modern scanners so when they go wrong it's easier to abondon them than pay the thousands it may cost to get it up and running again. Last time I was with a company that had one, there were no drivers for OSX so the company had to maintain a machine running on OS9 specially (another reason it may have been abandoned). Might be worth finding a local specialist to come out and check it over/test it. If its goosed they'll know.
