Question about Brother IntelliFAX 4100 Laser Fax
Our fax machine will get a dial tone and begin dialing, but before it's finished diaing we hear a fast busy signal and eventually receive a printout that reads "Busy: Busy/No Response" at the end. We've changed the phone cord, unplugged the power several times, and tried faxing to different numbers. Any ideas? The machine was working fine until about a month ago.
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.
