imageCLASS MF644Cdw Scanner - inconsistent working

I get this error message more often than not:

Cannot communicate with any of the scanners.

The scanners may not be connected, or may be turned off.

The OS is 10.14 OSX - However the problem has existed is 10.10

This is a new machine; new configuration (not transferred or upgraded).

The firmware is upgraded. I reset the printer 644cdw to factory and reconfigured.

The Wifi is in the same room less than 10' away. It's a new DECO x75 Pro (2.4, 5, and 6GHz). The IP address is fixed with a reservation. I have set the network settings in the software to the IP and the Bonjour address.

I can scan with the iOS business print. I can print. I can access the UI and the UI says scanning is available. Scanner works locally and via iOS app.

What am I missing here? The printer is on 2.4GHz, the Mac Book Pro (M3) is on 5ghz and 6HZ. IPs work no firewalls. Sometimes this works and sometimes it doesn't

Hello,

If you are able to print and scan consistently from other device and only have the issue when scanning from the Mac, it will usually point to a network communication issue or security or a service on the computer is causing interference. In this situation I would suggest contacting support over the phone at 1-800-652-2666. They can check what is causing the communication issue.
