Important Information
The DP-2000 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. The DP-2000 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 erroneous mail may be
returned from the Mail Server to the DP-2000.
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.
DP-2000 Cannot Make a Phone Call via LAN
The DP-2000 can only make a phone call using a regular telephone line (PSTN).
Dual Port Communication
The DP-2000’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.
Internet Mail Reception
1. The DP-2000 can receive text email from a PC and print ANSI characters. It will print a " " symbol if an
unrecognized character is received.
2. Received email font and character size are fixed and cannot be changed.
3. Text email will be printed at about 72 lines per page. It is recommended that you use A4/Letter size
recording paper.
4. If the received text email includes a file attachment in a format other than TIFF-F, such as Word, Excel,
Power Point, the DP-2000 prints an error message instead.
5. If the received email includes attached TIFF-F formatted image files, the text and TIFF-F formatted image
file will be printed on separate pages.
