Installed Windows 10 and now can't scan with Imageclass MF3240.

I uninstalled and reinstalled downloaded Canon drivers but still can't scan.  The printer works fine with Win. 10.

Hi EitzenCity,
I had a similar issue recently. We use Google Chrome as the main browser, and uninstalled and reinstalled it. This has helped, and the scanner is now working.
I am not clear on the details of why, though it may be worth a try if Google Chrome is the main browser.
Kind Regards
