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!

This approach (Jake807) worked for me also. I previously tried removal\reinstall of the Canon drivers and Scan utility on multiple machines to no avail. ( I had also tried the KB install and an update rollback on one machine)

By deleting the Twain files as part of removal and the reinstalling of the Canon drivers and Scan utility (No need for a separateTwain install) The MF Scan Utility and the Scan to computer functions on my MF424dw all work on all machines. Now to bring forward the machine I did the rollback on...

Thank you Jake for posting this!

I followed these steps for my MX922 (Windows 11) and it worked for the printer, but I still have no Scanner, or the icons for scanning in the Canon Quick Menu.

In Windows Settings, the printer shows "Scanners not Appearing".

Does anyone have a fix for this?

This fix did get my Canon ImageCLASS MF455dw working after the Windows 11 24H2 update.  However, it seems that the printing and scanning both run very slow until I reboot both the computer and printer.  This happens after what I would consider not a lot of printing, maybe 50 to 100 pages.  Any idea why this is happening and a way to maintain a reasonable performance speed?

I managed to install printer and scanner for MF8580Cdw under Win11 Pro 10.0.26100.
- remove owner 'Trusted Installer' from directory 'C:\Windows\twain_32' and delete directory
- download Canon drivers: MF8500CMFDriverV420WPusEN.exe, ToolBox4911mf18WinEN.exe, NetworkUSBScanPatchEN.exe
- connect PC and printer 1:1 using ethernet cable (to block PC internet connection)
- disable Windows Firewall and Real-Time protection
- install above mentioned 3 setups and reboot
- re-enable Windows Firewall (Real-Time protection should be re-enabled by Windows automatically)
- folder C:\Windows\twain_32 now should contain 2 subfolders: MF8500C and MF8500C_XXXXXXXXXXXX where the X's correspond to the MAC address of the printer

I asked  diff LLM chatbots , few of them with deepSearch:
I have on my laptop windows 11 home 24H2 , USB Type-C port and two USB Type-A ports, all operating at USB 3.2 Gen 1 speeds.
I have cannon scanner lide 300 and tool CanoScan Toolbox 4.9
This scanner lide 300 is not able to communicate with CanoScan Toolbox 4.9 and windows 11 home 24H2
But this scanner lide 300 is able to communicate with CanoScan Toolbox 4.9 on virtual machine with windows 10
How to fix this ?

solution from mistral.ai:    Use Windows Fax and Scan:
If the Canon software still doesn't work, you can use the built-in Windows Fax and Scan application as a temporary solution. This app can often detect and use scanners even if the proprietary software fails.

This quick "solution" is working fine for me  .

That solution is posted earlier in this thread.  There are both advantages and disadvantages to using the built-in Windows tool.

I finally gave up and bought a new printer that is Windows 11 compliant...

[macnet427]

I almost did the same but did get it to work. I'm only buying a printer if absolutely necessary.

My MX922 works perfectly with Windows 11. I also bought a new printer (MF656Cdw), which worked perfectly only after I followed the instructions in this thread.

Perhaps if you try to completely uninstall and reinstall the software for the MX922, it will scan as designed.

Also, my last Windows Insider update (Preview channel) allegedly contained a fix for this problem. With already working printers, I have no way to know if it works, but that was the claim.
