Use error correction mode
Error Correction Mode
(ECM) eliminates data that is lost 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 you can accept
poorer quality in exchange for reduced charges.
The following rules apply to ECM:
●
If you turn ECM off, this applies only to faxes that you send. This does not apply
to faxes that you receive.
●
If you turn ECM off, set the
Fax Speed
to
Medium
. If the
Fax Speed
is set to
Fast
, the fax will automatically be sent with ECM on. For information on changing
the
Fax Speed
, see
Set the fax speed
.
●
If you send a fax in color, the fax will be sent with ECM on, regardless of the
option currently set.
