I have successfully used a Brother MFD with the utilities provided by 
the Brother web site. I'm using Mint 19.2 and my notes say:

1. Download brscan and brscan-skey for your architecture from
https://support.brother.com/g/b/downloadlist.aspx?c=us&lang=en&prod=dcp7065dn_all&os=128&flang=English

2. sudo dpkg -i --force-all brscan4-0.4.2-1.amd64.deb 
brscan-skey-0.2.4-1.amd64.deb

3. nmap -sT 192.168.1.0/24 | awk '/report/ {ip=$6} /printer/ {print $1,ip}'

This should show the IP address of your networked printer

4.  brsaneconfig4 -a name=Brother model=DCP-J132W ip=<result of nmap> 
(eg 192.168.1.250)

5. brsaneconfig4 -q | grep Brother

Almost certainly true, but perhaps Canon provide similar tools.
