Transmission Settings

This section describes how to set additional fax transmission functions.

ECM Transmission

ECM (Error Correction Mode) reduces the effect of system and line errors on
documents that may occur when sending or receiving documents to or from
another fax machine that supports ECM. If the other machine does not support
ECM, this setting is ignored.
If transmission speed appears to be extremely slow, you may be able to speed up
the transmission time by setting ECM 'OFF'.
IMPORTANT
•
If you want to transmit using ECM, it is necessary that ECM transmission be set in both
6
the destination machine and this machine. This setting is ignored unless ECM is set in
both machines.
•
Even when ECM is set, errors can sometimes occur due to a poor telephone line
connection.
•
If there is trouble with the line it will take more time to send the documents.
NOTE
The default setting is 'ON'.
