I was also affected by this problem. The MFP support AirScan, therefore it is possible to scan with such interface. Very recent version of SANE support this, but for old SANE versions you can find an driver here. https://github.com/alexpevzner/sane-airscan I've install it from the repository and it works!!! I can scan any modes with hi resolution (600 dpi).
