Using a cell phone, call your fax machine to see if the fax answers. If it does answer, then hang up the cell phone and fax. Next, using the HOOK button on your fax, call your cell phone . The cell phone should ring and answer the phone call from the fax. If you do not get a connection between the fax and cell, try these: Check that the phone line to the fax is plugged into the LINE jack on the fax, NOT THE PHONE jack. The PHONE jack on the fax is to plug in a TELEPHONE ONLY. If the fax phone line is OK, go into your fax machines' RECEIVE and SEND settings and make sure they are set up properly (pulse or tone dialing, overseas mode, etc.) Print out the HELP LIST as follows: Press MENU button, then 5 on keyboard, then 1 on keyboard. Go through all the settings on the HELP LIST that apply to your problem. (Send and Receive modes, Ring Delay, Receive Options,etc.) Write down the original settings BEFORE YOU CHANGE ANY OF THEM.

I have a Brother mfc 290c. My problem is it won't send faxes, it keeps saying "no response, busy" I have a duet line. I have tried every combination in the book but still can't seem to find the solutions...

If you get the "busy/no response" message it is because the fax machine does not get a response when it tries to dial out.
Make sure you have a dial tone by pressing the "hook" button. If you do not have a dial tone, make sure the phone line is connected to LINE on the machine.
If you have a dial tone, try dialing the fax number. If you hear a recording, there is a problem with the line.
One of these two possibilities is causing the problem.

Fax is always busy when sending, have the line into the phone line port and into the telephone jack, fax scans and dials and even redials but it never go through, prints out receipt that says busy/no...

Has it always done this, or did Fax once work? Sadly, Windows XP Fax has many shortcomings, not the least of which is that it won't work with many modems still in common use. Modem incompatibility is not apparent during installation or the initial setup. It only becomes apparent when you try to send or receive a fax. The Fax Service will dial or will answer an incoming fax but then fail with any of a number of unhelpful error messages such as "Line is busy," "There is no answer," or "Reception error." There will be nothing in Event Viewer to give a clue as to where the problem might lie.

These errors have been nearly impossible to track down. To do so requires enabling both PSS and debug logging of fax transmissions, both of which require fairly extensive registry changes. For the time being, the best advice is to attempt to use XP Fax only if you have a modem that is listed on the Windows XP Hardware Compatibility List and using the latest drivers.

Hope helps.

Fax busy, no response yet fax is sent ok

NG or poor line condition on the transmission report means that there is interference on the phone need to double check the quality of the dial tone-if it static or,other interferences could be caused by other devices on the same line as your fax such as DSL modems.make sure first that you connect the brother machine directly to the walljack and try resending a fax.modem settings can be changed.e-mail me if you need that info

Can't send out fax

the number you called does not answer or busy-you may have reached a number not connected to fax or it is connected and not activated in receiving mode-check the number and call again.
if you have a message "out of memory"there is no enough memory available to send your stop/exit print the faxes stored in the memory to delete them then try again.

Can't send out fax

Make sure the phone cord is connected to fax machine in the place marked LINE, then make sure the phone cord is connected to the wall jack. Pick up your handset and make sure you have a clear dial tone also. If you are dialing long distance make sure you have the long distance service.

We can't send or received faxes

Just a suggestion. This effect can happen if you have plugged the line cord into the tel jack instead of line jack.

go into menu
go to fax settings
find send
click auto not manual, please make sure that when you push the hook key you hear a dial tone. always reminder that every fax machine has the capablitiy of either dial or tone. now if everything is set up properly  the problem will be in the tx portion of the board. if you can link up with somebody close to you and try to transmit back and fourth that will let you know if it is their problem or your. it may not be your problem.
