Question about Brother MFC 420CN All-In-One InkJet Printer
Always get a busy signal now. was not doing that at first.
I called Canon about this. They had me tweak the transmission start speed (Menu>FAX setting>TX settings>TX start speed). It was too fast. Set it to 4800. Then it was too slow. Clicked it up to 7200 and now it works!! TX Start Speed should not be too fast or too slow.

I am having my phone service checked out because I did get one fax to another number.
