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.

OKIFAX 4580 - Comms error

Hi just a note to say first theing to check is that the phone line is connected at both ends to correct sockets and that the connector to teh fax unit is connected to the line socket and not the phone socket as this is the main cause of line errors.. Good luck you could also check to see of you need to dial 0 or 9 first before you dial your number as you ma y be on an exchange line.. also check the fax settings to see if you have set the line type correctly either pulse or tbx..

Brother FAX 8360P comm.error

It could be line noise on the phone.., which allows phones to work ok, but causes problems with faxes. See this document from the brother website concerning comm.error:

Would recommend having the phone company run a line check to make sure the phone line is clean of interference !
