First thing to check is the condition of the phone line, if the machine has a handset make a phone call from the handset, is the line clear? Is there any static or Echos on the line?
Is the machine on a shared line with computers or an answering machine?
Call the Fax machine from a phone, is the line clear? did the machine generate its handshake burst? Did anything else try to answer the line?
Check the phone cable input, it should be going onto the LINE jack on the back of the machine.

Replace the phone line cable.
Remove the handsetn or at least unplug it.

Hope this is of some help.

My fax machine was working great up until this morning. I am able to send faxes but not receive them. The machine is hooked up to the phone jack and shares the line with our credit card machine. It is not...


It's entirely possible that your fax machine will just miraculously start working again. If it was hooked up to your computer you'd possibly be getting an error message, which when interpreted by its code number, would tell you it's not receiving the phone signals correctly for a period of time but soon will.

Hope I'm right,

Regards,

Hp photosmart c309a I get error 387 after my first send fax. what shall i do?


there are 3 possible reasons you are getting this error.

First :It could be a bad phone cord connected. try with another phone cord.
Second : the phone cord you are using is 4 wire conductor ( HP printers use 2 wire conductor ) and
3rd : It could be faulty line ( There is too much noise on the line for a valid connection between two fax machines to complete. The noise problem might go away over time.)

Solution : Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.

Try running the Fax Test from Printer Setup Menu.. Press Setup and under Tools - you will find Run Fax Test - Check which all parameters it did not pass.

If you hook a regular telephone up to the line, and try to make a call, do you hear static? or low voice or tone? The line itself could be bad, or the wiring int he phone plug in the wall could be lose. If that's the case u can unscrew the plug form the wall and make sure all the wires are good. Other then that all you can do is have the phone company come test your phone line, and/or get a new fax machine., but most likely it is your phone line and not the fax machine.

I have a 410 error on an incoming fax


Definition

During a V.34 transmission, the local machine is unable to connect (handshake) with the remote machine and is consequently unable to send a T30 frame. This occurs when the line is disconnected or if line conditions degrade during the session.

Solutions
  • Remove any pass-through devices from the phone line, and then try the fax again.
  • Confirm that the fax/phone cable is no longer than required, and that it does not pass near unshielded electric motors such as fans, heaters, or household appliances.
  • Try to send the fax at a different time when telephone line conditions have improved.

Using MagicJack for faxing; however, Brother MFC 290C is stating poor line condition - why? Also say's low ink Magenta - would that create this problem?


I had the same problem trying to send out faxes out using my Brother MFC 7340. I use a magic jack phone line. Page 106 of the user manual says if sending via VOIP phone line, you should press menu, then 2, 0, 1 to select "Basic (for VOIP) mode. Then press ok. Then press stop/exit. This cuts the modem speed down to 9600 bps and turns ECM off. Then retry to send the fax. I did that and can now send and receive faxes.

Cannot receive faxs


The majority of non receive issues are phone line problems.
3 conditions must exist for a fax to receive, the phone line voltage must be high enough, the phone line current must be high enough the the DB gain must be correct.
A fax receive should be viewed in the same way a remote controle works.
When you send a fax, you manually access the phone line when you select send, you connect to the phone line, normally via a relay. Once that physical connection is made, it can send anything. Maybe not well, but it will send.
Where as receiving is an electrical signal that activates the machine. If your phone line is not up to standard, its like haveing a remote control with weak or dead batteries and trying to turn on your TV with those weak batteries in it.
Issues, simply a bad phone cord between the machine and phone jack. Some resistance may have acrured over the years. The phone jack itself may have a poor connection.
A staticy phone line will cause a fax not to pick up. Plug a phone into that line and see if there is any noticible static.
Multiple devices plugged into the phone line with the fax machine. ETC an answering machine, credit card machine, etc can cause more of a draw on a shared line, if that is the situation, at least for a test, remove everything but the fax machine from the line and see if it receives then.
Rarely if the machine can send and not receive is the machine an issue.
Have your phone lines checked well and that sould resolve the issue. And make sure the line is not plugged into the extension or phone jack on the machine, but plugged into the line jack. That is also a common problem.
