I can receives faxes but when I try to send a fax..I keep geeting a n ECM Error report? Why?

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.

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.

Doubt if you need to set up the fax with ECM ( error correction mode )...a lot of fax's come with ECM these days set to ON. Don't know why because in the majority of cases the phone lines are of good enough quality that its not necessary. However, that said; I would suggest you pick up your handset and listen to the dial tone on the phone/fax line and listen to see if you are hearing static noises...if you do then its likely you have a bad line and should report it to your phone provider.
If the line is good, then I would ask you to try and make a phone call off your fax machine(assuming it has a handset) and again listen to the sounds off the line. I would then get someone locally with a fax machine to send you a test page to see if the machine works from a different number/location.

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...

Error 344 means :-

The remote machine has failed to respond to a fax command from the product because the connection is interrupted.
The remote user has pressed the Stop button while the remote machine was receiving.
Under rare conditions, incompatibility between the two machines can cause the remote machine to simply abandon the call.

Solutions :-

1. Attempt to send the fax again when telephone-line conditions have improved.
2. If the fax session was using error correction, disable ECM.

To disable ECM Press :-

1. Press Setup .
2. Press the Down arrow ( ) repeatedly until Advanced Fax Setup displays.
3. Press OK .
4. Press the Down arrow ( ) until Error Correction Mode displays.
5. Press OK .
6. Press the Right arrow (> ) until either OFF or ON displays.
7. Press OK .
8. Send another fax to verify that the ECM is enabled or disabled.

Check the Phone Cable connected with the printer.
Make sure the Cable should be connected to line 1 port at the back of the printer and it should be going directly from the printer to the wall jack and not to the Serj protector.

Try to print a fax test page.

1. On the control panel of the product, press the Setup button ( ).
2. Press the Right Arrow button ( ) to select Tools , and then press OK .
3. Press the Right Arrow button ( ) to select Run Fax Test , and then press OK . The product displays the test results on the control panel display and prints the Fax Test Report.

Now Do this :-

1. Send a one page black and white text fax to 1-888-hpfaxme (1-888-473-2963).
2. When your fax is received by the HP Test Fax Service, we will generate a return fax to you within five minutes confirming that we received your fax. This verifies that you can both send and receive a fax with your fax machine.

If you do not receive a return fax within 5-7 minutes, there may be a problem with the setup of your fax machine. Consult the user manual that came with the product for proper setup and configuration. Try the above steps and let me know if it works for you.

1 Press Setup.
2 Press 1, then press 1.
This selects Print Report and then selects Automatic Reports Setup.
3 Press ! to scroll through the following report types:

The error 244 results from a fax machine communicating and trying to 'Poll" your fax. (receive information you have loaded into the fax memory for all to receive) The error comes in when your fax has no information or is not set up to be polled.

Look in your menu for the "ECM" setting on the printer menu. If this error is getting persistent change the ECM setting to the opposite of what it is set now. More than likely your fax will say ECM=On, change to off.

If you have problems locating where the ECM section is, print a "settings report" or "printer menu".

Hope that helps you.

344 Error can be caused by a few things. One of the following is occurring:
The sending fax has failed to respond to a fax command from the receiving fax due to poor line quality or fax interruption.

The sender has pressed cancel button while the reception was in progess.

In rare conditions, incompatibility has been encountered by two faxes and causes the sending fax to abandon the fax call.

Solutions:
Fax session was using ECM. Check your fax settings under the fax set-up menu on the printer. Disable the ECM (Error Correction Mode).

Fax at a different time to see if line quality improves.

Try relocating the fax to a differnt phone plug.

Replace the phone cord attached to the fax/printer.

You can configure your HP all-in-one so that it automatically prints error and confirmation reports. If you need printed confirmation each time a fax is sent, follow these instructions before sending any faxes and select Send Only. To set automated report options from the control panel Press Setup. Press 2, and then press 1. This selects Print Report and then selects Fax Report Setup. Press to scroll through the following report types: Every Error: prints whenever there is any kind of fax error (default). Send Error: prints whenever there is a transmission error. Receive Error: prints whenever there is a receiving error. Every Fax: confirms every time a fax is sent or received. Send Only: prints every time a fax is sent indicating whether the fax was successfully sent or not. Off: does not print any error or confirmation reports. Press OK to select the report.

Display the fax menu and then select Print Report\List and print the Users Data List. Check the setting of the ECM TX setting. If this is ON turn it OFF. This is the Error Correction Mode setting, probability is the fax you are sending to is not ECM compatible. The MP830 is suppose to automatically send in standard mode if receiving machine is not ECM compatible however I am not sure how well this works. Turn the ECM setting off by displaying the Fax Menu and then select Maintenance\Settings, Device Settings, Fax Settings, TX settings, ECM TX.
