Brother Intellifax 3550

Try calling the fax machine from your mobile and see if it picks up or if anything shows up on the screen of the fax machine. Is it possible that you have plugged the fax machine into the wrong telephone line? Try sending a fax to your mobile phone and see that the number is correct.

If the fax is not set for tone dailing and it is set for pulse dialing the fax will not register the # button.

First you enter phone line in to the fax machine and then feed the fax paper on the top side of the fax machine then dail the number on the dail pad after the beep press the start button your fax start work.Fax throughput and office productivity are enhanced by scanning faxes into memory while the machine is busy. You can return to work, confident that their faxes will be transmitted as soon as the line is free.

Have you tried another regular phone on the same jack? There is a small LIU board in the fax that the phone line plugs into and it is possibly bad. Inexpensive board from Brother. Buy a whole unit from EBAY cheaply.

Do you have a dial tone?

Bad low-voltage power supply.

Fax machines are ANALOG devices and will not work reliably on a DIGITAL phone line . Filter makes no difference.

Same thing happened to ours here at work except it was the #3 that got stuck. It was idle for 3 weeks because no one took the time to see what was going on. Five seconds on Google and 20 seconds on fixya.com and we have a working fax machine again.
