I installed my Brother MFC-J470DW in Deepin (15.5 Desktop 64-bit), and it went through everything without an error including the scanner. However, the printer works fine, but my system says there is no scanner found when I try to use SimpleScan.
Is there something else I need to do to get the scanner to work? There is nothing I can find in Settings.
I went to the Brother page and downloaded the installation tool, and ran it through Terminal. Part of the installation clearly was setting up the scanner, although the only time it asked for the address of the printer was as a printer. My printer is wireless on my network.
Open a terminal and use the command sane-find-scanner. If that doesn't work, do it again as root. If you can find it as root but not otherwise, it's a permissions problem. I have noticed with HP all-in-1's that udev often treats them as printers only. The same may be true for Brother.
Some of the components in this how-to are in your Brother MFP, and I would suggest the setup program you ran should set that part up. However, the system you run as the client, needs configuring too. Have a look at that part.
You could connect the printer/scanner to your system with a USB cable, and see it sane-find-scanner finds it. If yes, try scanning over USB, that is easier to configure. Then you will know this is a configuration problem over wireless.
It would be worth a look on Brothers support pages to see if they have any help for network scanners.
Hope this helps.
