The issue is still not resolved by any of the patches issued by Microsoft. Not the ~667 one and not by the .NET patch some are speculating about.

Tested for countless hours in the recent days and still having issues. Identical system of Windows 11 23H2 works, but on clean installed Windows 11 24H2 it does not work no matter what tricks we have tried on 100s of Canon printers, mostly C1127i, C1333i, MF744Cdw, MF443dw, MF463dw, even some older MF411dw across multiple organizations and multiple IT admins.
I am 100% sure and tested its nothing to do with some policies or security software, as those printers (with latest FW, checked) does not connect to scanner even on multiple of my personal devices which are clean installed, and also tried multiple 24H2 VMs - same error "Cannot communicate with the scanner".

Tried everything, even disabling firewall, making sure services are working and even comparing registry keys between 24H2 and 23H2 installs to find out whats wrong with 24H2.

Maybe there is someone here who can actually get a real human at Canon to look into this, as the support does not understand this and wants to exchange the device instead, but it's not the device issue, it's a software issue. Hundreds of new PCs are stalling because users cannot scan documents from MF Scan Utility or even from the printer LCD when clicking send to PC, it does not connect and gives an error.

Everything mentioned above is exactly my issue too (MF410).

Issue remains on a clean 24H2 install that has these KBs installed.

Have 3 PC's here, 2 laps, 1 desk. All 3 already had the 24h2 update already installed (12/10/24). None will connect to the Canon scanner (printing is fine). I also removed the 24H2 and tried scanner - no-go.

Uninstalled win update, re-installed it. Uninstalled the canon drivers & re-installed. No change in symptoms

Curious is that we also have a monochrome "Brother" printer/scanner. 1 laptop will scan when initiated from the printer, but not from the PC. Neither of the other 2 will connect to the Brother either.

Both printer/scanners had been working with the 3 PC's for quite some time. The desk & 1 laptop were recently refreshed software wise - fresh win11 & apps re-installed.

I'm convinced it is a MS Windows issue - hope it get resolved SOON!

My printer isn't connected via USB cable as discussed in the above article you mentioned, HOWEVER, it should be noted that I had previously attempted scanning with a USB cable after initial scanning failure, but that too failed.

As soon as I reinstalled a disk image I had just recently made before upgrading 23H2 to 24H2 the scanner worked again, so 100000000% guarantee it is yet another Windows F-UP in 24H2

Of course its an issue with 24H2 not being compatible with Canon current software version, but only the Canon folks have the capacity to debug it and see what exactly goes wrong. Tried a WinDbg tool but still nothing, seems to be failing at some security related DLL in syswow64 but Im not a developer/expert, Im a hardware guy.

Same Issues here after performing a fresh install on W11, updated the OS and then installed the new download of the drivers and scan utilities. Still having the same issues with scanner unable to communicate with the utility.

I was able to get windows to install the printer and scanner using control panel. As of right now I am able to scan using Windows Scan app. Just not using Canon MF Scanner utility.

Reading the last entry - without any more re-installs, i simply tried the MS Scan app (windows Store download) and that app works for both my Canon & Brother printer/scanners. A bit less function, but can scan again.

Still want Canon to get with it and fix their software!

I'm glad that worked for you... I had read about the scan app working on a different site I found while searching Google about this, and of course tried it, but that too failed. It said something along the lines of "You must install a scanner first". O'well. I'm content running 23H2 for the time being. However, I wish to hell Microsoft wouldn't screw with things that don't need it and/or do proper testing with devices that might be affected. It's not like they don't have the $ nor can they say that every single printer/scanner is the exact same throughout the entire company or at the various developers homes. T E S T T E S T T E S T!!!!!!!!!!!!

We appear to have a solution. See this thread:

https://community.usa.canon.com/t5/Printer-Software-Networking/Fix-For-MF-Scan-Utility-Failures-Windows-11-24H2/td-p/520000

MF Scan Utility and ScanGear working after following the steps in the link above.

Any news on an actual fix? I've a new build 24h2 Pro that won't see the mf216n scanner. Printing is fine. Another 24H2 upgrade likewise can print but not see the scanner. Apps see no scanner. Device Manager doesn't show one. The box had been Win 10 and all worked fine.

Why doesn't Canon have a page about this???? I understand this is likely a MS foul up, but no page with updates????

Neither msu files work for me. Was these .msu files for Win 11 Pro and not Win 11 Home or would it not matter?

My Canon is the MF445DW

Here is the translation of your text into English:

"Windows 11 24 h21 update Incompatibility with Canon i-Sensys MF445dw scanner"

Is there a solution?

As of today (February 27th, 2025) Windows 24H2 still causes scanner failure. Additionally, this appears to be happening with other scanner manufactures, not just Canon. Clearly a Windows problem. There is absolutly no way that SOMEONE that works for Microsoft hasn't also experienced this and reported it, which means MS doesn't give 2 sh*ts about its consumers and figures we will just have to wait until they are ready to release a fix. 😞
