Set default scanner

I use Skanlite and it identifies 3 different devices as scanners. One of them is a Brother MFC printer, connected by WIFI, which I would like to set as the default scanner. How can I set it as default? Should I use a different scanning software?

I tried simple-scan, installed from the repo, and it is an improvement, because it automatically selects the Brother printer from the list. But it still goes through the unnecessary and time-consuming process of searching for all possible scanners.

Did you even look at the manual page for simple-scan?

What about (and the following is from a web search):

simple-scan -?

or

simple-scan --help-all

I don’t see what I am looking for in there:

        simple-scan -?

Maybe I’m doing something wrong but I don’t see what I want in there.

With Skanlite I tried this one

skanlite -d [device name]

But no luck.

Make sure you read the SANE page on teh ArchWiki. Also look at the problems page as well.
