Question about Brother IntelliFAX 4100 Laser Fax

Have dial tone, but can't fax

Our fax machine will get a dial tone and begin dialing, but before it's finished diaing we hear a fast busy signal and eventually receive a printout that reads "Busy: Busy/No Response" at the end. We've changed the phone cord, unplugged the power several times, and tried faxing to different numbers. Any ideas? The machine was working fine until about a month ago.

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.

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...


Hello,
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.
Thanks,
Pat

Since you mentioned that you have an outside line, do you have to use a code to dial out normally? Try plugging in a phone to the line for your fax machine, and attempt to dial the number for the other fax machine using the phone. You should reach the fax and hear a high pitched sequence of tones. This is the other fax machine trying to establish a connection. If you still get a busy signal, try calling the owner and letting them know that their fax machine is not accepting incoming calls.

Problem: Busy/No Response on all outgoing faxes


Put the document you want to send into the transmit tray, pick up the handset, listen for a dial tone, and then dial the # on the keypad..
It should ring just like any other phone. When the machine on the other end picks up and you hear the tones, press the start button.
Anything other than fax tones on the other end, it is not your faxes fault.

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.

The number that you are sending to is either busy, disconnected, or off the hook. To chek BEFORE dialing press the "HOOK" button (located to the left of the "1" key) and listen to the transmission this will help you in your troubleshooting. If you don't hear a dial tone BEFORE dialing, then the trouble is on your end.
A fast-paced busy signal could indicate a "downed" telephne line.
Finally, sometimes the line that you are sending to has so much stuff hooked up to it (56K dialup fax, multiple phones, alarm system dialer, credit card validator, teenage daughter) that you may be better off e-mailing instead.

No dial tone, clicking sound


It most likely is the LIU (Line Interface Unit). or you might have it plugged in the wrong port on the fax itself. Make sure it's plugged into the LINE plug. If it's the LIU it would be cheaper to replace then calling for service. Unless it's under warranty still (usually 90 days)
