Send a fax in Error Correction Mode
Error Correction Mode (ECM) prevents loss of data due to poor phone lines by detecting errors that
occur during transmission and automatically requesting retransmission of the erroneous portion.
Phone charges are unaffected, or might even be reduced, on good phone lines. On poor phone lines,
ECM increases sending time and phone charges, but sends the data much more reliably. The default
setting is On. Turn ECM off only if it increases phone charges substantially, and if you can accept
poorer quality in exchange for reduced charges.
Before turning the ECM setting off, consider the following. If you turn ECM off:
●
The quality and transmission speed of faxes you send and receive are affected.
●
The Fax Speed is automatically set to Medium.
●
You can no longer send or receive faxes in color.
