imageCLASS MF753Cdw Scan Problem, cannot communicate with scanner

[Eschwege]

Hello I just bought this printer, I know it works I have a fault Cannot communicate with the scanner. cable disconnected blah, blah blah. This is a windows problem. I reinstalled windows with Ver. 24H2 and setup the printer-scanner and it works however I guess the system is updating its files and it no longer sees the scanner.  What is the fix?  I haven't even had the printer a week, very frustrating.

Greetings ,

This is a known issue with feature release. 24H2.  Doesn't happen with previous feature releases.  Microsoft is aware of the issue, however they have not provided a date for a fix.  Unfortunately it's affecting multiple manufacturers.

Thank you, I appreciate the help.

Thanks for your expertise and willingness to help.  I too have experienced scan issues. Strange that one of my systems can scan, but the other one cannot, but using Microsoft scan, it works - does not work for the Canon scan software, ver 1.21.02.  with driver 5.2.  On my other system, which is similar, they're both HP's, Canon scan ver 1.11.0.1, with driver 5.2, Canon scan works. Both are Win 11, ver 24H2.

I believe I tried upgrading printer/scanner driver to ver 7.12, but no joy.

Very puzzling...

I just had to do a Clean Install of Windows 11 and found too that the MF Scan Utility would not communicate with my MF726Cdw.  I even installed (and left it in place) the Windows 10 (x64) [Windows 32-bit & 64-bit] Patch for Network Scan, USB Scan.  Still no luck.

During my Windows 11 re-install, updates also were installed: 2024-12 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5048667) and 2024-11 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 24H2 for x64 (KB5045934). 

Still had issues UNTIL...

An optional Windows update was also posted: 2024-11 Cumulative Update Preview for .NET Framework 3.5 and 4.8.1 for Windows 11, version 24H2 for x64 (KB5048162) was installed today and voila!!  MF Scan Utility now communicates with my MF726Cdw!!  It looks like Microsoft fixed something.

I just looked, I already have that update and my MF Scan utility still does not work.  I will try and do a reinstall and see if that changes anything.  Thank you
