2.SENDING/RECEIVING A FAX
ECM
Switch the ECM (Error Correction Mode) communication ON or OFF. ECM is an internationally standardized
communication mode that automatically corrects errors that occur during fax transmissions. With this setting option ON,
even when the transmitted data have been affected by noise during communication, this mode allows good
communication without image distortion by automatically resending the parts that have been affected.
 Both the sender and the receiver must have the ECM function to make ECM communication available.
 When affected by noise during communication, communication time is slightly longer than usual. Even when the
ECM communication is used, an error may occur depending on the line status.
 The ECM communication is not available for voice communication.
QUALITY TX
Switch Quality TX ON or OFF. When this mode is set to ON, originals are sent at a slower speed than usual and the
chances of errors occurring decrease.
