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?

I will say this, I was able to allow microsoft to install the printer and completely removed the cannon app and driver and I can now use the Windows Scan app to scan. On my older printer the scans are partially garbled, but on the newer machine the scans come out clean and that is the solution I am working with at the moment.

This is great news!!  We need to get this solution out there for others.  💣

I however only have one device entry under my Imaging Devices for the 644 & 656.  I'm running 23H2 on this system so its not affected.
