About Internet Fax
You can perform the Internet Fax function that provides the ability to transmit a scanned
original as an E-mail, with an attached TIFF-FX (Profile S) file. Since an Internet line is
used instead of a phone line, the communication cost can be reduced.
In this function, an E-mail address is specified in place of a phone number to transmit a
scanned original to the Internet Fax equipment or the client computers.
When the Internet Fax is received, it is automatically output like regular Fax.
NOTE: The administrator needs to configure the network settings for Internet Fax to function.
See the Network Administration Guide.
