Brother MFC-7820N Scanner not working

This question has nothing to do with bios, it has to do with help getting my scanner working. If anybody could help me sort out the various info I’ve found concerning it I’d appreciate it, otherwise please PM me and I’d be happy to discuss it.

Please let me clarify this, I made this statement without having access to my PC or my old emails, now that I’m at my PC I see that the bios thing was with my Broadcom wifi problem, not with the scanner. Both were in the same few days and I confused them. Could we please just stick to my problem from now on?

So much info to sort through and maybe I’m too dumb, but I hope to find someone who’s done it before and could give me the short form. As I said, I’m new to Manjaro and I’m slowly learning that each Linux flavor has it’s own quirks.Thank you in advance!
