Enabling ECM Transmission - Canon imageRUNNER ADVANCE 4251/4245/4235/4225 e-Manual

Enabling ECM Transmission

You can send fax documents using the Error Correction Mode (ECM).

ECM reduces the effect of system and line errors on documents that occur during sending or receiving with another fax machine that supports ECM.

For information on the optional products required to use this function, see "Optional Products Required for Each Function."

IMPORTANT
If you want to transmit using ECM, it is necessary that ECM Transmission be set in both the destination machine and this machine. This function does not operate unless ECM is set in both machines.) 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 transmission time by turning ECM 'Off'.

Press

(Settings/Registration).

Press [Function Settings] → [Send] → [Fax Settings].

Press [ECM TX].

Press [On] → [OK].

Select [Off] if you do not want to enable ECM transmission.

IMPORTANT
Even when you set ECM, 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.
