When you try to install the scanner driver downloaded from Brother website for models like MFC-240C or MFC-7340 on recent releases of Fedora Linux, you most likely will encounter this or similar issues:

rpm -ivh --nodeps brsca2-0.2.5.1.i386.rpm

/usr/local/Brother/sane/setupSaneScan2: line 7: /etc/sane.d/dll.conf: No such file or directory

If you try to list:

ls /etc/sane.d

ls: cannot access '/etc/sane.d': No such file or directory

The information on the internet mostly will not give you a direct solution but instead gives you many things to try, which ends up not working for me. I tried different releases of the Fedora and finally found out the issue. From Fedora 31, somehow sane-backends package was not installed automatically, even though sane-backends-libs are.

Somehow installing xsane will not install sane-backends either. Package sane-backends provides the necessary file structures to hold the scanner driver configurations and related files. So do:

dnf install libusb libnsl sane-backends

then install the proper driver following the instruction of Brother should be fine (libusb and libnsl are recommended by Brother for recent releases of Fedora).
