    I have the same model fax with the same message - poor line condition. I have a number of phones and an answering machine on the same line (all operating with no problems). I have moved my fax to another jack but get the same message. Any ideas?

ECM error message


Noise in the phone line, or low signal strength during fax transmission can result in fax failures. Noise or poor signal strength can cause a partial or complete loss of fax information during transmission. When Error Correction Mode (ECM) is on, the receiving fax machine checks the fax information for errors during reception. If the receiving fax machine detects an error, the receiving fax requests that the sending fax resend the information. Resending all or part of the information can make transmission times longer, but helps improve the quality of the received fax.
If the phone line quality or signal strength is extremely poor, sending a fax can fail. Turning off ECM can improve the ability of the product to send a fax successfully when the phone line quality is poor. However, the image quality of the received fax might be poor.
If ECM must be off to send faxes successfully, have the telephone service provider check the phone line quality. For an HP Fax, turning off ECM from the control panel does not necessarily mean that fax transmission will not use ECM. Fax products use ECM as follows.
  • All faxes sent in color use ECM.
  • All faxes sent at the highest transmission speed use ECM.
  • The ECM setting affects only sent faxes, not received faxes.
Enabling or disabling Error correction mode (ECM)
  1. On the product control panel, press the Menu button (c01743394.gif ).
  2. Use the arrow buttons (c01073166.jpg ) to select Basic Fax , and then press the OK button (c01335940.jpg ).
  3. Use the arrow buttons (c01073166.jpg ) to select ECM Mode , and then press the OK button (c01335940.jpg ).
  4. Use the arrow buttons (c01073166.jpg ) to select On or Off , and then press the OK button (c01335940.jpg ) to confirm the setting.
  5. Press the Back button (c01496476.gif ) twice to return to the main screen.

inernational fax calls quite often do not work on digitized phone lines or via satellite. You cannot fix that. maybe your fax has a "fallback 4800 bps" setting that might be helpful.

Sending fax error message."Phone


No. Most of the time this "phone line error" can be caused by the telephone connection or issue on the phone line where the fax machine is connected.
Hope this will help.

If this is happening to only one number you're trying to fax to, then the problem is most likely on their end, not yours. If it is happening with all the numbers you fax to, then I would suggest checking the telephone line hooked to the fax. Look for loose connections, or perhaps a bad cord from the phone outlet. The connection could be good enough to get a dial tone, but not secure enough for the fax to operate. If none of that holds true, I would suggest taking it to the shop and let a technician look it over.

Poor Line Condition message


If your fax has a handset listen to the dial tone and make a call if the connection is poor call the phone Co.

NG: POOR LINE CONDITION / OUT OF MEMORY


You can adjust the Compatibility mode. This adjusts the sensitivity of the machine to interference on the phone line by lowering the transmission speed:
a. Press Menu, 2 (Fax), 0 (Miscellaneous), 1 (Compatibility)
b. Press Up or Down arrow to select "Basic"
c. Press OK.
d. Press Stop/Exit.
e. Try resending the fax.
If the problem continues we recommend you try the unit on another line at the current location or another location. Always restart your machines after you made changes, that way you will see the results.
