My multifunction Printer / Scanner doesn’t have any scanning functions available under macOS 10.13 High Sierra.
The scanner function worked under macOS 10.10 Yosemite.
I’m still able to scan using the iOS app.
Resetting the print system from the instructions in this question has not solved the problem: Brother MFC Scanner not recognized any more
- Brother MFC-9335CDW
- macOS 10.13.6
- Driver package file: ColorLaserFB12_ULW_112_3.dmg
Under macOS 10.10 Yosemite there was a “Scan” button on the top-right of the panel in the picture above.
