What is Internet Fax?
What is Internet Fax?
It is a feature whereby scanned documents are transmitted to Internet Fax or to computers as Email. 
Internet Fax communicates via an Intranet or the Internet without using the telephone line.
This machine can be connected to 10 Base-T/100 Base-TX/1000 Base-T Ethernet LAN (local area 
network).
„Sending Email
Scanned documents can be transmitted to an Internet Fax or a remote computer as files attached to an 
Email.
zRefer to Sending Email (see page 104).
zScanned documents are transmitted as attached files in the TIFF or PDF format.
The PDF format can be used only for transmitting documents from an Internet Fax to computers.
zThe remote PC must support MIME to receive file attachment in the TIFF or PDF format.
„Receiving Email
When an Email is received from an Internet Fax or a computer, the Email message is printed 
automatically with the image of the attached file.

What Internet Fax Can Do
This section introduces the functions of the Internet Fax feature.
The Internet Fax feature not only sends and receives Email but also forwards fax documents via a 
telephone line and broadcasts them via a relay station.
Sending Email
A scanned document can be transmitted to an Internet Fax or a remote computer as an Email file 
attachment. Attached files must be in either of the following formats:
•Internet Fax: TIFF format (TIFF-F)
•Computer: Select either TIFF (TIFF-F) format or PDF format.
zFor more details on sending Email, refer to Sending an Email Procedure (see page 114).

Receiving Email
When this machine receives Email from an Internet Fax or a computer, it starts printing the Email 
automatically. If the Email has an attached file in a format that is not supported by the machine, an 
error message is printed to alert you that the machine cannot print the Email.
zFor instructions on how to receive Email, refer to Receiving an Email (see page 136).
Inbound Routing
A document received from a G3 fax station via a telephone line can be forwarded to a remote computer 
on the network, an Internet Fax, or G3 fax. The forwarding destination can be specified by sub-
addressing, or the numeric ID of a fax station.
zFor more details about routing, refer to Inbound Routing (see page 142).

Relay Transmission
The Internet Relayed Transmission feature can save your time and transmission costs if you need to 
send the same documents to multiple G3 fax machines. This is especially true if the transmissions are 
long distance.
You can send documents to any G3 fax machine by using the Internet via a LAN from your machine to 
another relay station. You can also send an Email with attached TIFF-F file(s) to any G3 fax machine 
from your PC using your current Email application through a relay station.
To convert applications, such as spread sheet, into a TIFF-F format file, however, requires you to first 
download the software (TIFF converter) from the web site listed below.

Ex: Internet Relay Transmission
zWhen requesting Relay transmission from a computer, it is necessary to transmit the file in the TIFF-F format.
zThe application software is available from the download site. Refer to Convenient Application Software (see 
page 162).

Message Delivery Notice (MDN)
If the sender (Internet Fax) desires a processing confirmation, it must request a Message Delivery 
Notice when sending the message to a device supporting the notification function.
Several Email applications such as Eudora
® and Outlook® Express support and are able to respond to 
the delivery confirmation notification sent from the Internet Fax, as well as sending a request for 
notification to the Internet Fax by Email applications that support the Message Disposition Notifications 
function.
„If the Receiving Station is an Internet Fax Station
A Message Delivery Notice (MDN) with communication capability notice is returned to the sender.
„If the Receiving Station is a Computer
An MDN response Email message is transmitted to the sender.
zThis feature can be used when the receiving station supports the Message Delivery Notice (MDN) feature.
zTo enable this feature, refer to Setting Message Delivery Notice (MDN) (see page 132).

Direct Internet Fax Transmission (Using Direct SMTP)
Email is normally distributed by an SMTP mail server using Simple Mail Transfer Protocol (SMTP).
In common cases, only Internet Email and Web service are permitted into the corporate intranet, and 
corporate network administrators are extremely unwilling to open the firewall for other incoming 
services, since each opened path represents additional potential security threats.
The Direct Internet Fax feature enables documents to be directly exchanged between Internet Fax 
stations without the intervention of an SMTP mail server. This will reduce workload of SMTP mail 
server.
Use of this feature requires that IP Addresses always have to be kept unique. Certain information, such 
as the domain name of this machine, also needs to be properly pre-programmed in the DNS server.
To use the Direct Internet Fax feature, set the Function Parameter “172 Direct IFax XMT” (Fax/Email 
Settings > Fax Parameters) to “Va li d”.
zFor more details on the network configuration, contact your network administrator.

Tips for Internet Fax
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 Switched Telephone Network 
(PSTN) are as follows.
„Differences between Internet Fax and Fax Stations on the Telephone Line
Fax stations connected to the telephone line transmit data over a telephone line at their own expenses.
Internet Fax, on the other hand, breaks down image data into packets, and transmits them from a LAN 
to the Internet or an Intranet without using a telephone line, thus the telephone bills on long-distance 
calls can be saved.
„When Email Transmission Fails
• Your machine does not directly connect to the final destination, but rather connects to a mail server 
via LAN. Therefore, if a document cannot be correctly transmitted due to an error, the error mail may 
be returned from the mail server to your machine.
• Error mail may take a long time to return (20 to 30 minutes normally) depending on the location of the 
remote stations, the degree of line congestion on the Internet, or the network configuration and so on.
• Depending on the mail server, it is 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.
• Documents may not be transmitted to a remote station correctly if the remote station’s mailer does 
not support MIME. Error mail may be returned depending on the type of the remote mail server.
• Documents consisting of multiple pages or including a large amount of image data may not be 
transmitted.
zIf the Function Parameter “172 Direct IFax XMT” (Fax/Email Settings > Fax Parameters) has been set to 
“Valid”, documents are directly transmitted to Email addresses pre-programmed in the Address Book.
zThis machine supports the Message Delivery Notice (MDN) feature. Program this feature when you want to 
make sure whether the Email you sent has reached the receiving station successfully. For more details, refer to 
Message Delivery Notice (MDN) (see page 107).
„Telephone Calls Cannot Be Made via LAN
• Your machine can only make a phone call using a regular telephone line (if an external telephone is 
connected to your machine).
• Fax communication cannot be performed using Voice Over IP network communication.
