Fix For MF Scan Utility Failures Windows 11 24H2

[Dale_1973]

I have been frustrated by this issue also. I bought a new desktop machine and it immediately updated and installed Win11 24H2 on it. I then installed my Canon software for my printer MF750C and the MF Scan Utility would fail with the message mentioned many times in this thread.

I have installed all the latest updates and including the one Microsoft released 12/10/2024, KB5048667, but none of that made the scanner software work.

Now today I reinstalled just the drivers for the MF750C under the Imaging devices in Device Manager, and it started working, and has kept working as I think I have tested after rebooting at least 10 times today.

So bring up Device Manager, (right click on the Start Menu), expand Imaging devices, then right click your device, mine says Canon MF750C Series, (2 times). Now this part is important as I checked it twice and if you don't Disable the device first it doesn't seem to work right. So right click on the device and click Disable Device. My MF750C is listed twice here in Imaging devices, so be sure to Disable Device for both of them. Then right click on it again and select Browse my computer for drivers, then select Let me pick from a list of available drivers on my computer. Your printer/scanner should be in the list, make sure it is selected, then click Next.

Mine then came back and said Windows has successfully updated your drivers. Make sure you do this for BOTH of the devices listed there, at least if it lists two of them. Windows does say it updated the device driver. I'm not sure what it did for sure but it did something.

It doesn't say you have to, but I then rebooted my machine before I tried the software, but then the MF Scan Utility works! It has kept working for 2 days now, and after many reboots!

I don't know if this will work for everyone but so far it has worked for me. I have no ideas what made it work today. Microsoft and Canon, (and apparently HP and Brother), need to talk and get this resolved for people!

Merry Christmas!

Thank you!  This fix worked for me with an ImageCLASS MF455dw.  The printing via Wi-Fi had been troublesome after the Windows 11 24H2 update.  I previously got the printing to work but the scanner stopped working again.  I hope it stays fixed after this repair.

I tried this method, disabled the printer from device manager and then browsed my computer for drivers, and pointed it to search the drive where I downloaded the drivers from canon to.  But then it told me I already have the most updated drivers installed.  Should I install the drivers before trying all these?

I think you have to do this sequence:
1.  Open Control Panel
2.  Open Device Manager
3.  Open Imaging Devices
4.  Open 1st Canon MF720C series
5.  Select Driver tab
6.  Select Disable Device
7.  Repeat 4, 5, and 6 for second Canon MF720C series
8.  Open 1st disabled Canon 720C series
9.  Select Driver tab
10. Select Update Driver
11. Select Browse my computers for drivers
12. Select "Let me pick from a list of available drivers on my computer"
13. Select Microsoft eSCL Class Driver
14.  Repeat steps 8 through 13 steps for second Canon MF720C
15. Restart PC

I think your mileage with vary on how well this works.  As I said in my post, this worked partially for me (feeder scan on both sides was not available), I only got this to fully work by reinstalling the latest Canon drivers and then scanning both sides with the feeder starting working.

I think it is important to reboot your computer, and then immediately go to device manager and disable the device, then try update the drivers. Do not try to print or scan after you reboot the computer.  I don't know if this will work but I hope it does for you.  I just wish Canon would acknowledge this issue and actually put out software to fix the driver issue.  Good luck.
