I have 2 computers on my network that have an error when trying to scan to my MF644CDW Printer/scanner.
It says "Cannot communicate with the scanner. The cable may be disconnected, or the scanner may be turned off. Check the scanner statue and try again. Scanner driver will be terminated."
I can print to the printer and the scanner selector software sees the printer/scanner and when I install the MF Scan utility software it sees the scanner. It works fine from other computers on my network, but not 2 of them. All windows 11 computers. I have tried everything I can think of like disabling the firewall and security settings. What could be causing this and how can I fix it?

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!

Greetings,
Please click the start button on your windows desktop. After you click, type winver and press enter. What Feature release of windows are you running? Example 23H2, 24H2?
Do you have 3rd party anti-virus installed?
Did you install the MF Scan Utility v1.21.0.2?

Version 24H2 (OS Build 26100.2314) and yes v1.21.0.2

No 3rd party antivirus installed

Also, the Windows Scan app works fine so it has to be the Canon MF Scan Utility app.

We're having the same issue except the printer is a MF751. The Windows ScanApp worked once but never again. We've uninstalled and reinstalled about three times with no luck. The Canon MF733 they had before worked just fine but it died.
Have you had any luck since yesterday?

Still no solution

I am also having the same issue with MF451dw. Two of my computers on the network get this error message, and I believe they both happened after a Windows 11 update. I can print but not scan. Reinstalled the drivers and MF Scan Utility several times with no resolution.

I forgot to mention that the Windows 11 Pro workstation is 24H2. We tested a fresh install on a 23H2 workstation and the software works fine.

In the last 2 weeks the number of posts regarding this has increased. One user reported success using 24H2 on 3x systems.
I'm afraid this is something to do with 24H2 feature release as there are posts about it on Microsoft's community that include multiple printer / scanner manufacturers.
I'm going to raise this internally with the Illuminary group.
