Panasonic 3000 User Manual

The DP-2500/3000 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.

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.

1. The DP-2500/3000 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-2500/3000.

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.

The DP-2500/3000 can only make a phone call using a regular telephone line (PSTN).

The DP-2500/3000’s dual port capability, allows simultaneous G3 Fax Communication over regular telephone
line (PSTN) and LAN Communication.

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.

1. The DP-2500/3000 can receive text email from a PC and print ANSI characters.  It will print a "n " 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-2500/3000 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.
