Tips for Using Internet Fax
Your machine uses the same communication protocols as Email: the Simple Mail Transfer Protocol (SMTP).
The differences between the Internet Fax and the standard G3 fax communication using the Public
Switched Telephone Network (PSTN) are as follows.
Differences Between the Internet Fax and Fax Stations on the Telephone Line
Fax stations which use telephone lines to send faxes incur charges from telephone companies.
Internet Fax, on the other hand, breaks down image data into packets, and transmits them from a LAN to
the Internet or the 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 the
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 large amounts of image data may not be transmitted.
• If Fax Parameter No.172 (DIRECT IFAX XMT) has been set to "2:Valid", documents are directly
transmitted to Email Addresses pre-programmed in the Address Book.
• This 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 79)
Telephone Calls Cannot be Made via the LAN
• Your machine can only make a telephone 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.
Dual Port Communication
Your machine has Dual Port Capability allowing simultaneous G3 fax communication over a telephone line
(PSTN) and LAN Communication.
Transmission Resolution
In view of PC transmission, the standard setting of the Fax Parameter No.2 (RESOLUTION (HOME) ) is set
to "1:Standard". If required, this setting can be changed to "2:Fine". (See page 153)
Receive Internet Email Messages
• Your machine can receive text Email from a PC, and print ANSI characters. It will print an " " symbol if an
unrecognized character is received.
• Fonts and character sizes in received Email are fixed and cannot be changed.
• Text Email will be printed at about 72 lines per page. It is recommended that you use A4 / Letter size
recording paper.
