ECM HOW DO I DISSABLE THE ERROR CORRECTION MODE?

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 ( ).
2. Use the arrow buttons ( ) to select Basic Fax , and then press the OK button ( ).
3. Use the arrow buttons ( ) to select ECM Mode , and then press the OK button ( ).
4. Use the arrow buttons ( ) to select On or Off , and then press the OK button ( ) to confirm the setting.
5. Press the Back button ( ) twice to return to the main screen.

try to disable Error Correction Mode (ECM).
to do so:
Press Menu . Press the Right Arrow (>) until Advanced Fax Setup appears. Press Enter . Press the Right Arrow (>) until Error Correction Mode appears. Press Enter . Press the Right Arrow (>) until Error Correction Mode ON or Error Correction Mode OFF appears. Press Enter . Send another fax to verify that the ECM is enabled or disabled.

ECM (Error Correction Mode)
The Error Correction Mode (ECM) is a way for the fax machine to check the integrity of a fax transmission while it is in progress. ECM transmissions are possible only between machines that both have the ECM feature. If they do, you may send and receive fax messages that are continuously checked for their
integrity.
Sufficient memory must be available in your FAX/MFC for this feature to work.ECM (Error Correction Mode) Detects errors during fax transmission and resends the page(s) that had an error.
If you have Call Waiting, RingMaster, Voice Mail, an answering machine, alarm system or any other
custom feature on a single phone line with your fax machine, it may create a problem sending or
receiving fax data.
For Example:
Your Brother machine handles the Caller ID and Call Waiting/Caller ID subscriber services.
However, if you subscribe to only Call Waiting or some other custom service and its signal comes
through the line while your machine is sending or receiving a fax, the signal can temporarily interrupt
or disrupt the fax data. Brother's ECM feature should help overcome this problem. This condition
is related to the telephone system industry and is common to all devices that send and receive
information on a single, shared line with custom features. If avoiding a slight interruption is crucial
to your business, a separate line with no custom features is recommended.

is the phone line stable..meaning no distortion ... if there is some distortion like static sound.. you won't be able to fax properly.. try enable to ECM mode in your fax unit.. ECM is error correction mode.. it should reduce the send/rec error...

ECM (Error Correction Mode) is a feature common in most fax machines today. It helps to minimize errors while transmitting faxes over noisy phone lines.

1) Be sure you have the latest version of the drivers installed
2) Turn the fax off, then unplug for 10 minutes, turn on and try again. This should clear up anything in the printer/fax memory
3) Check if your phone line is unsually noisy when you tried to send the fax(es) that gave you the error message. If this is the case, a sucessful fax transmission will be almost impossible. You may have a faulty phone line or an improper installation. Either of these two should be fixed by your phone company. Also, most phoen companies can test your phone line (for fre) remotely to check for abnormally high noise levels.

Turning off ECM / lowering baud rate, neither will matter. Fax machines are ANALOG devices. MagicJack, Vonage, DSL are DIGITAL phone lines.

Your fax machine will not wot work reliably.

ECM ( error correction mode) resends a fax that error was detected and was not transmitted.

Not sure it can be turned off. Try printing whatever is in memory.

here is the manual
