I have a Canon ImageCLASS MF8380Cdw combo printer scanner; I've had it since 2012. The scanner worked through many Windows10 updates right up until May 2019. When I tried to scan something through MF Toolbox I got the message "A supported scanner cannot be found".
CANON SOLVED THE ISSUE WITH A WORKAROUND -- but I cannot find again the Canon post to which I can add this reply. Here's what I did that had no affect on the problem: 1) uninstalled the software program, 2) reinstalled the software program, 3) went to Canon website and downloaded all updates for: firmware and drivers and the scanner patch for the 8380
None of the above efforts fixed the problem. Then I came across the Canon workaround thank goodness because I can't find it again. Here what worked for me as I followed Canon's instructions:
> Right click on the Canon MF Toolbox 4.9 icon
> Left click on "Properties" at the bottom of the window
> Select the "Compatibility" tab at the top right corner of the window
> Select the "Change settings for all users" tab at the bottom of the window
> Select "Run this program as an administrator" at the bottom of the window
> Click "Apply" and then "ok"
My first attempt at opening the MF Toolbox worked without getting the error message and I was able to use the scan toolbox as I have always used it in the past.
THANK YOU CANON
