Issue description
When performing a Network Scan on any of the printer models stated above with your mac OS 10.12 (Sierra), only an AirScan user interface (generic UI) will appear and the Lexmark features will be missing.
Since these multifunction printers support AirScan, the Mac OS will bypass the custom ICA Scan Driver and the scan will happen via AirScan.
