|That's a very old scanner, you can try Canon but I doubt you will find any. One option is go into device manager, click on imaging devices. If your scanner is showing right click on it and choose update drivers and get windows to look for one.|
If that fails you will need to invest in a new one, even the cheapest new scanner will be better then the old one.
You may also consider getting a MFP (printer/scanner in one) takes up less space.
