Hi,
Just bought this machine.
Followed the instruction and when start testing everything:
Printer is working via USB and Wifi.
Scaner is working via USB but is not working via wifi. When using MF Scan Utility, I can see only Canon MF643 USB and when trying to scan without cable I receive Pop Up " Cannot communicate with any of the scanners. The scanners may not be connected, or may be turned off.". Also you cannot find scanner in Printers and Scanner. Only Printer.
My Mac OS is Mojave 10.14.6
How to fix it?
Best,
Gleb
