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.


Hi,
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.

Cant send fax dials squeals and cuts out and busy signal?


Hi There!
Please check if the phone line where the fax machine is connected is working. You may try to disconnect the fax machine from the walljack and connect known-working telephone on that jack and try to dial/call anyone. Because sometimes this issue can be caused by the problem on the phoneline.
Hope this helps. Please rate if it works. Thanks

I am unable to use my fax when it worked before, say's busy/no signal. The last time I was able to use it was in January 2010


Verify the connectivity (phone line) first by pluging a working telephone in the wall jack, than test the cable from the wall jack to the fax, you could install a Y to plug a working telephone with the fax on the same line to spy on what is happening when the fax is engaging a connection.

Cheers!

WE CANNOT RECEIVE OR SEND FAXES, BUSY/NO SIGNAL


Plug a phone into the jack and check to make sure you have a dial tone. If not telephone company needs to be called. If dial tone it may be the other number you are trying to fax to. try calling the number from phone and see if it picks up.

Receiving faxes


If you are receiving a fax and you pick up the telephone before the fax machine answers it, the fax will never be able to respond to the fax being received. I assume that is whats happening. If you have a phone connected directly to the fax machine and you pick it up from that phone, the fax machine should transfer to itself after 2 seconds when it recognizes that it is a fax machine.
If you are going to do it from anywhere else, you need to get a fax detector device connect it to the main phone jack, and have the fax machine go to the fax jack of the connector and the other phone in to the other lines, make sure you have enough sockets on the fax detector.

thanks

Difficulty sending a fax


Hello. Please make sure your telephone line is plugged into the correct outlet.

Most fax machines typically allow you to plug the line (the cord that goes from the fax machine to the wall jack) and and a telephone (the telephone connects to the fax machine).

In order to fax correctly, you must plug the line into the jack with a block (looks like a 'T') marked on it. Do not plug the line into the jack marked with a phone hand set marked on it.

This shoulds in detail how to connect the line properly. For this printer the line cord must be plugged into the jack labelled "L"

This will show you how to actually send the fax. On your PDF View select page 42.

Fax doesn't recognize incoming phone call


Try this: using a cell phone, call your fax. Listen on the cell for a busy signal, fax tones, dial tone, etc. If the fax does not answer the cell, check the following: make sure the phone line is plugged into the LINE jack on the fax, NOT THE PHONE JACK. The phone jack is to connect a TELEPHONE to the fax. If problem still exists, press MENU on your MFC, and scroll to GENERAL SETUP, FAX. Scroll to SETUP RECEIVE, and, after writing down the settings, try changing the RING DELAY or RING TIME settings. If problem is still there, press CLEAR/BACK button until GENERAL SETUP appears on screen. Scroll down to INITIAL SETUP, and select RECEIVE MODE. Try changing RECEIVE MODE settings. Write them down before you change anything.

Multiple fax copies only 1 or 2 get through


First check to see if all 5 are bing sent. Sometimes paper sticks to each other and you may only see 1 or 2. Also your telphone line has a lot to do with it. If you are using a digital telephone line with your internet line such as a vontage telephone, the signal is takene from your internet line for your telephone and sometimes such as when you are on the internet and trying to fax, you do not have enough signal strength. sometimes sutting off the internet works. Also what does the report say from your copier/fax are 5 pages being sent. In the set up this Canon you can get a report after you send a fax....

Continuous Fast Busy Signal


Your modem/fax board is most likely bad. there is a relay on that board that has probably failed. It is stuck. I doubt it can be made to work. those are really small relays on those boards.
