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.

Im using the Brother MFC 7820n at a hotel. how do i fax? i've tired 9+1+area code+the number, 9+area code+the number and a few others but nothing seems to work, what am i doing wrong?

Depends on the hotel.
Some have a specific dedicated line that allow direct dial (no 9). Some block long distance calls and required the use of a calling card.
Otherwise, dialing 9 should work.
Can you hear the dial tone? What kind of sound do you hear when it fails? Is ti list a fast busy signal? Or do you just hear nothing?
If they have the speaker off, try to call your cell phone from the FAX just to see if it can make an outbound call at all.
Also, try tracing the wire from the fax machine. Make sure it is plugged into LINE and not PHONE. (or the jack with the picture of a wall jack, not a picture of a phone). Some hotel patrons disconnect FAX machines to use the phone line on their laptop modem and then neglect to properly reconnect the fax machine. Also make sure it is connected at the wall.

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

When I dial a fax number I get a busy signal even though I know that the number is not busy because I have dialed it on my outside line and it works. This has happened repeatedly. I have unplugged...

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.

Every time I try to fax I get a busy signal. I tried to fax several places and I get the same thing cannot be completed as dial.

dial those numbers from a regular phone and listen for fax tones. If you hear a busy signal, then they are busy.

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.

Status 50 on a fax estudio 45

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.

The machine seems to work ok, except when putting in a fax document, inputting the #, and pressing fax start, it pulls the document through, then just beeps every 2 seconds. It then does put out a...

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.

Fax machine error

I called Kodak support and had to upgrade firm software and reset all the settings to reflect whether I had an answering machine (yes) and call waiting (no). Also found it helpful sometimes to dial out using commas after the 1, to keep it from ringing busy.
