MF Scan Utility Cannot Communicate with scanner MF644CDW

[lonquist]

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?

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

[lonquist]

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.
