ECM (Error Correction Mode)

The Error Correction Mode (ECM) is a way for the machine to check 
a fax transmission while it is in progress. If the machine 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 
machine.Your machine must have enough memory for this feature to 
work.
