Fixed mine. There are no Windows 8 drivers available on Canon's website or Windows Update. Follow these steps to install a Canoscan 8400F scanner under Windows 8 x64 in desktop mode:

(1) Download and install the Windows 7 x64 drivers from the Canon website.

(2) Launch Device Manager, right-click and uninstall any (?) unknown device, then rescan for new hardware and the Windows 7 x64 drivers will automatically install.

(3) Download and install the Canoscan Toolbox software from the Canon website.

(4) Launch the Canoscan Toolbox software, select Settings, and click the Reset button to repair the non-working Copy/Scan/PDF/Email scanner buttons.

(5) Reboot.

Button functionality is restored after the reboot. Everything works as designed now. Good luck!

    I too recently paid for the upgrade to Windows 8. I'm so frustrated with the USB drivers, and now my scanner. I've had to plug in my logitech keyboard and mouse again and again to get them to work. Thankfully that went away. Logitech's software and Microsoft's mouse stuff was conflicting somehow.

    Anyways, I too have a scanner issue. I tried to install drivers by changing the compatibility to Windows 7, but nothing. Also ran as administrator. Problem is, even on Windows 7 (my kid's computer the scanner isn't showing up either).

      1. Do you receive any error code or message?

    • Windows Fax and Scan says "No scanners were detected.... [instructions goes on about rebooting computer and to try help]
      1. What is the make and model of the computer?
    • answer: Custom Build - AMD Bulldozerwith MSI motherboard 990
      1. What happens if you try to scan?

    Dear Sir,

    I tried to reply u via yr provided email address MicrosoftAnswers@microsoft.com but not successful. BTW, hereby is my answer...

    1. HP OfficeJet 6500 AIO printer
    2. & 4. No problem for printing & fax. While scanning, an error message 8, [(0,18,-2147467259)] is occurred and the scan process is failed.
    3. Lenovo B570

    I also used the printer & scanner diagnostic utility to check the device, it prompted that TWAIN driver error. However, when I used the MS Paint and scan a document, it worked successfully. Also, I reported this error to HP tech support but cannot get any answer. Do u have any idea to fix this problem? 

    Tks for yr help.
