Using the e-mail notification function
If a communication completes successfully, a transmission result notification e-mail is sent from the machine to a specified e-mail address.

The job history may differ from the machine's transmission results. In that case, the machine's transmission results have precedence.
For details, see Web Image Monitor Help.
If there be any insufficient configurations of the Internet Fax or e-mail transmission on this machine, or if [Auto Specify Sender Name] is set to [Off], the Email TX results or LAN-Fax result notification e-mail is not transmitted, and the TX results report or LAN-Fax Result Report is printed. See "Connecting the Machine", Connecting the Machine/System Settings for the Internet Fax settings, and see LAN-Fax Result Report for the LAN-Fax Result Report.
