Internet Fax Transmission

This machine converts scanned document images to e-mail format and transmits the data over the Internet.

The e-mail sent by this machine can be received by another Internet Fax machine. Instead of dialing the telephone number of the destination you want to send to, you enter the relevant e-mail address (Internet Fax destination). If the machine at the other end supports T.37 full mode, bi-directional exchange of data such as available paper size and resolution is possible.

You can receive e-mail messages with an attached TIFF-F image from computers.

You can send the same document to fax destination, IP-Fax destination, and an e-mail destination, folder destination, simultaneously.

You can also print or forward received e-mail messages.

  • To use Internet Fax Transmission, this machine must be connected to a LAN and set up correctly in “System Settings”. For details about the required settings, see “Connecting the Machine”, Network and System Settings Reference.

  • You can also enter a computer's e-mail address as the destination. In this case, you can send TIFF files only.

  • To send Internet Fax documents, in the Facsimile Features menu, under Initial Settings, set [Internet Fax Setting] to [On]. However, documents can still be forwarded or delivered to Internet Fax destinations even if [Off] is selected. See “Initial Settings”.

  • To receive Internet Fax documents, in the System Settings menu, in File Transfer, under [Fax E-mail Account], set Account to [Receive]. See “File Transfer”, Network and System Settings Reference.


  • The Internet Fax function supported by this machine is compliant with ITU-T Recommendation T.37.

  • Though Internet Fax documents are normally sent via an SMTP server, you can also send Internet Fax documents directly to their destinations without going through an SMTP server. To do this, set whether or not to bypass the SMTP server on the standby display. For details about using this function, see “Bypassing the SMTP server”.

  • When sending Internet Fax documents, “Subject”, “Text”, “Reception Notice”, “BCC Transmission” can be selected in [TX Mode]. For details about setting these options, see “Other Transmission Features”.

  • You can limit the size of transmitted e-mail messages in “Max. E-mail Size” of “Facsimile Features”. For details about the setting, see “Send Settings”.

  • See “Received images” for how e-mail is actually received by the computer.

  • The CC function is disabled.

  • If you send Internet Fax documents specifying a user code, and the e-mail address is set as the routing destination of the specified user code, a Communication Result Report is sent after the transmission is completed. This makes it possible to verify the result of a transmission.

  • For details about how to confirm the transmission result, see “Checking the Transmission Result (Transmission File Status)”.

  • This function supports both IPv4 and IPv6 addresses.
