Re: unable to send fax

There are several reason:
Do you have chosen the right connection (cable)?
Is the cable inserted well?
Did you choose the right software settings (press menu/fax etc. all writen inside the manual)?
Did you have a look at the faq?:
(choose your country, your printer and the FAQ section. Here you can choose fax)
Did you had a lighting strike the days before? (The fax modul will be defectiv)

Fax problem

I want to make sure I understand this completely. You get no dial tone from the fax machine when hooked up to VOIP. In the past, was there an audible dial tone from the fax, or did it just dial silently and give you an error if there was no tone? When you said you got a dial tone by connecting a phone to the ext phone port of "the machine" did you mean the fax machine? If you get a dial tone by running a phone through the fax machine, then the line is good. I have used a fax machine over Sunrocket before they went defunct, which used the same technology base as Vonage - so it should work. If you used to get an audible dial tone when using the fax, and no longer do, and you are geting a dial tone on a regular phone that is connected to the ext. port of the fax machine, then the problem has to be in the fax machine itself, not the VOIP. If you can verify that, we can go from there.

No dial tone when pressing hook fax is returned

The only thing that could stop you from sending a fax or not get a dial tone, would be the connection to the phone line. Make sure the telephone wire is plugged into the line jack (not ext jack) and should go straight to the wall, without splitters or extensions. If you still cannot send a fax, try another wire or jack

No dial tone pressing hook, NG and Poor line condition transmission report on sending and receiving. Confirmed good dial tone on line in and on phone on ext. Copy, display, everything else fine. I hear...


Make sure that you have your telephone line from the wall jack plugged into the port on the fax that says "LINE" and that your telephone is plugged into EXT.

All your cables and jacks seem like they are working since your phone gets a dial tone, the onyl thing could be that the wires are mixed or the modem on the fax is broken.

When I hit hook to send a fax I hear a click but I get no dial tone and the same on receiving a fax MP830

You only hit hook to hear the dial tone or use the machine like a speaker phone. To send a fax you press fax start. If you can't hear a dial tone when you press hook, there is something wrong with the phone line connection, or it's plugged in to the wrong plug on the machine. The phone line goes into the one marked with an L, the other with the pic. of a phone is for an additional telephone.

I am unable to send fax, I get a 'phone line error' message. The phone line is fine, I checked it by pluging a seperate phone into it. When I go to 'On Hook Dial' I do not get a dial tone on the fax...

Please check the dial tone by following the instructions given below:
1. Press "Fax Mode."
2. Press "Menu."
3. Press "Up Arrow" or "Down Arrow" repeatedly until On Hook dial is highlighted.
4. Press "Select" twice.
You can now hear the dial tone of the telephone line.
5. Enter the number to which you want to send a fax.
Note: Press the keypad numbers to use an automated answering system.
6. Press "Start Black."

Problems sending and receiving faxes.

  1. Open Lexmak Productiviti studio - 5600 - 6000 Series ( icon on Desktop)
  2. Open Setup and manage faxes link ( left bottom corner)
  3. On Ringing and Answering card look at the Manual Answer Code ( if some nuber inside delete it, it should be blank)
  4. On Dialing and sending card look at the Dial method (if you have a tone phone select Touch - tone, and if you have pulse phone select Pulse)
The diference betwen Touche Tone and Pulse is that Tone when you press nuber hear tone (like on cell phone), and Pulse when you dial nuber hear serie of short pulses (like when you dial nuber 5 you hear 5 short pulses like tttttt)
