There are two methods of redialing: Automatic redialing and Manual redialing.
Automatic Redialing
Manual Redialing

Important
It may be possible that faxes will reach unintended recipients due to the misdialing or incorrect registration of fax/telephone numbers. When you send important documents, it is recommended that you send them after speaking on the telephone. For details, see Sending a Fax after Speaking on Telephone.
Automatic Redialing
You can enable or disable automatic redialing. If you enable automatic redialing, you can specify the maximum number of redial attempts and the length of time the machine waits between redial attempts.
Enable and specify the automatic redialing setting on Auto redial in Advanced FAX settings under Fax settings.
