Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
It should be easy enough.
1: you need a good phone line, or good phone line service. (Note: 'digital' phone service, MagicJack, or Comcast, for example, may not support fax operation.)
2: you need a phone cable from that phone service (or the phone jack) to the 'Line' or 'L' port on the Brother machine.
3: that's really about it.
What do you have for a phone line service? what results do you get so far?
Sending needs no programming.
Hit the FAX button, if there is one.
Then lift the handset, if there is one.
Wait for the dial one, briefly.
Then dial the number using the number keys. For instance, you could dial the HP Fax Test service's number, if you have no other number to fax to.
Then you ought to hear beep tones from the fax after it dials, at which point, you hand up the handset. The fax ought to go through by itself at this point.
