The scanning issues on the imageClass MF devices connected via usb has been my main source of frustration ever since switching to windows 11. I have about 30 workstations that are all exact the same spec and OS. Only about 5 of those had no issues installing the drivers with the official installer from the canon website. Another 10 would take like 5 tries to finally install. The rest of the workstations cant get the installer to copy the scan drivers. The workstations that are using Brother MFPs have had zero issues whatsoever.
