ECM (Error Correction Mode)
The Error Correction Mode (ECM) is a way for the MFC to check a
fax transmission while it is in progress. If the MFC detects errors
during fax transmission, it resends the pages of the fax that had
an error. ECM transmissions are only possible between fax
machines that both have this feature. If they do, you may send and
receive fax messages that are continuously being checked by the
MFC.
Your MFC must have enough memory for this feature to work.

telephone answering device) directly to your MFC.
Connect the telephone’s line cord to the jack labeled EXT. on the
back side of the MFC.
