ECM
ECM (Error Correction Mode) is an error correction mode defined by ITU-T (International Telecommunication
Union - Telecommunication Standardization Sector).
Fax machines that support the ECM communicate, while confirming that there is no error in the sent data.
This prevents image blurring caused by noise on the phone line.
By default, this machine uses ECM for transmission. If the noise level is high, the communication may take a
little longer than communication that does not involve ECM checking. To reduce the transmission time, you
can transmit faxes with ECM turned off. However, an image error or communication errors may occur de-
pending on the specified communication time value, so change the value to suit conditions.
Tips
-
When registering destinations with an address book, you can specify whether or not to send faxes in
the ECM mode in addition to registering fax numbers.
-
If the ECM function is canceled, the following functions cannot be used together.
V34 OFF, Polling TX, Polling RX
