Internet Fax Features
Important Information
■ General Description
Your machine uses the same communication protocols as email: the Simple Mail Transfer Protocol (SMTP). The 
differences from a standard G3 fax communication using the Public Telephone Network (PSTN) are as follows.
■ Differences Between Internet Fax and Regular Fax
A regular Fax machine goes off-hook, dials, and the phone network completes a circuit over phone lines to the 
receiving fax. You pay for the circuit. The two faxes negotiate a connection, synchronize and exchange image data.
The Internet Fax works like an email, the image data is broken down into packets and transmitted through your Local 
Area Network (LAN) to the Internet or Intranet instead of using a telephone company’s network, thus saving you long 
distance costs.
■ Transmitted Document Confirmation
1. Your machine does not directly connect to the final destination (see note below), but rather connects to a Mail 
Server via LAN. Therefore, if a document cannot be correctly transmitted due to an error, the erroneous mail may 
be returned from the Mail Server to your machine.
2. The erroneous mail may take a long time to return (20 to 30 minutes) depending on the destination location, traffic 
on the network or LAN system configuration.
3. Depending on the Mail Server, it is also possible that erroneous mail is not returned at all. Therefore, when 
transmitting important or time sensitive documents, it is recommended that you follow up with a telephone call to 
confirm reception.
4. Documents cannot be transmitted correctly if the destination Mail Server does not conform to the MIME protocol. 
Erroneous mail may not be returned depending on the Mail Server.
Note:
1) Fax Parameter No. 172 (DIRECT IFAX XMT), if set to "Valid", allows you to configure Phone Book so that you 
can directly send to the destination without medium of SMTP.
2) Your machine supports the Delivery Notice feature (see page 48).
■ Your Machine Cannot Make a Phone Call via LAN
Your machine can only make a phone call using a regular telephone line (PSTN).
■ Dual Port Communication
Your machine's dual port capability, allows simultaneous G3 Fax Communication over regular telephone line (PSTN) 
and LAN Communication.
■ Transmission Resolution
In view of PC transmission, the factory default setting for the resolution is set to FINE mode. If required, this setting can 
be changed to Normal.
