QUESTION I'd like to use my seven-year-old Canon CanoScan D1250U2 scanner with my new PC, but its driver isn't compatible with Windows 7 Home Premium 64bit. I can't find any new drivers for this model on Canon's website.

The scanner works perfectly with my old machine, so I'd rather not replace it unless I have to. Derfel Lester

HELPROOM ANSWER Although your scanner still works, it's getting rather long in the tooth in technology terms. It's not surprising that Canon hasn't written a new driver for it, although you may find a Vista one will do the trick. Surf here and select ‘Windows Vista' and ‘English' when asked which version you'd like to download.

If this driver doesn't work then you'll need to replace the scanner. Prices start at around £40 online, but check for compatibility before you buy; Windows 7 is still relatively new and suppliers may continue to hold older stocks.
