If you wish to use a Canscan N650U windows 7 and are having a hard time with the drivers auto installing or using the old/original drivers. Use VueScan!!! It's supposed to be able to let use a scanner even if your OS doesn't support it. I tried it with my friend's Canscan N650U and IT WORKED!!! He has Win x64.
VueScan lets you use scanners unsupported by your OS A freind of mine wanted to use his old Canoscan N650U windows 7 and are having a hard time with the drivers auto installing or using the old/original drivers. Use VueScan!!! It's supposed to be able to let use a scanner even if your OS doesn't support it. I tried it with my friend's Canoscan N650U and IT WORKED!!! He has Win x64. I had googled and finally after a while stumbled on to this VueScan page that mentioned it being able to work with scanners that the OS wouldn't work with. It is pay for but, if you don't mind water marks you can use the free version, or spend a bit of money for the full-version. I'm not saying buy it but, that is an option. older printers and scanners have better chance of working on 32bit windows 7 since it can use XP drivers but, usually that isn't the case with 64 bit windows 7.
To add to this, use the preview function to get a scan without the watermark, then use the prints screen key to save the pictures in mspaint.
Years ago, I began using VueScan to replace HP's PrecisionScan Pro which not only did a crappy job of scanning, but was also inconsistent in behavior across different versions for different scanners. Now that HP doesn't provide Win8 drivers for their older scanners (I have a 7400c and 6350), VueScan is even more of a godsend for me.
This is a good suggestion. I have several scanners that aren't supported any more and it didn't dawn on me that Vuescan might be using its own drivers. The couple times I've tried Vuescan though, it has been frustrating. Just scanning something at 200% at 300dpi was not straight-forward. Settings were not consistent with basic work flow and I kept getting inconsistent results. It's been a while so I'll try it again. Thanks again OP for the idea.
Yeah, the VueScan UI takes a little getting used to, but once you do, it works well. And it beats ponying up for another scanner.
