Busy signal when trying to send fax

Every time I try to send a fax on my HP PSC 950, as the fax number is being dialed, it sends out a busy signal, even though the number is not busy. Can anyone help me with any adivise on how to fix this problem? HP wouldn't help me because I bought the machine over a year ago...so you know what that means...NO FREE HELP!!

    No, I only have dial up, and this happens with every fax that I try to send, even when I have checked to make sure that the fax line is not busy, so as you can see, I'm still stuck, do you have any other suggestions??

    can you call your fax machine from a regular number? Seems that this busy signal may be from call waiting interruptions

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.

My Brother MFC7340 Fax Machine will not send faxes it has a busy signal always and a busy signal when someone tries to fax me.

You need to reset the memory, since previously you have dialed some number, which is not able to connect. So restart the printer. Unplug the printer for 10 minutes and plug back the power to the printer.

Hope this helps.


I have a Brother fax machine. When I dial a number to send a fax, there is a noise on the speaker in addition to the fax dialing and it defaults into a busy signal. What should I do?

The number u are dialing is either busy or someting is wrong with the phone line thus not connecting to the other party. The fax set up may be confiqurated wronlgy.


Each time I try to send a fax it says the number is busy when I know it is not

Dial the number on a regular phone and verify that the number ANSWERS with the fax tones immediately. If it doesn't, then the line will register as busy to your fax.

When trying to fax, iam getting a fast busy signal, this problem just strated

This could be related to the fax machine, but more than likely it's a phone line issue. Try sending a fax manually by using the fax machine's speaker or "on-hook", then manually dial the number. Listen carefully as the machine dials and make sure it's even dialing out. Do not hit start until you hear the other fax machine pick up. If the "fast" busy signal occurs before dialing is complete or right after, have your phone line checked.

If you get this on every number, check your setup and make sure that you haven't set it to add some extra number. Also try to send a fax to another fax number.

the number is busy. Try pressing the monitor button and listening for a dial tone. No dial tone means your phone line is not working. If you have dial tone, dial the number you wish to fax and listen to see if it picks up. If you get a busy signal, or hear someone answer, that is why it's not working. If you hear the fax tones, press start and send your document. This is a way to fax that allows you to hear the whole process.

Check the fax line with a regular phone and dial a fax number to listen for fax tones.

Can not send out faxes

You have to get your phone line checked out .


If you have dial-up for your internet access you cannot be online when a fax is coming through. The line has to be free to receive the fax.
