Cannot send or receive fax

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.

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.

Do you have or are you sending a fax to a party that has a DIGITAL PHONE SERVICE?

232-A communication failure has occurred between the two machines.
327-*Reattempt the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
356-The remote user has pressed the Stop key, causing the session to be aborted.
442-An error occurred during transmission after one or more partial pages had been sent. The transmitting machine was unable to restart the control channel (handshaking) before sending more data. This error typically occurs when the receiving fax disconnects after receiving part of a page but can also occur if the receiving fax is using a fax format that is incompatible with the HP fax machine (usually during color faxing).

Have you called your own fax line and just listened to the fax hand shake? might sound simple but I have called fax lines before and it just rang, or it was busy or static, if your not getting a clear fax hand shake, then it is the phone line, if there is no answer you may have turned your fax to manual receive mode, If you don't know how it should sound call a friends business fax line and listen to it. I have actually gone out to businesses that reported send or receive problems just to call the line and listen to a disconnect message, that would make it difficult to fax.
