|There is no Windows 7 driver for that scanner model as it is too old. However, if it connects via USB there is a good chance that software called "VueScan" will allow your scanner to work on Windows 7. The only snag is VueScan is not free. You can download a trial version from here to see if it works with your scanner:|
If it works, you then need to decide whether to pay for a licence key or pay for a new scanner, though these days buying a new flatbed scanner on it's own will not be easy as they are generally integrated in to a printer.
