RINT CONFIDENTIAL DOCUMENT

Secure Print is a feature that allows you to attach a password to a
print job on the computer, send it to the printer for temporary
storage, and then print the job from the printer control panel. When
the printing of a Secure Print job is complete, the job is
automatically deleted.

S

TORED JOB

A stored job is the same as a secure print job except that it is not
deleted from the storage device after it is printed unless you
specifically ask for this at the printer control panel. By storing
frequently-used data in the printer, you can print the job from the
printer control panel, without sending it from the computer again
and again.

IRECT PRINTING OF

PDF F

ILES

You can send a PDF file directly to the printer for printing without
using the printer driver. As the print data is sent directly to the
printer, the printing process is simpler than printing with the printer
driver and it is done at a faster speed. The way to print a PDF file
directly is as follows.

Using PostScript Feature

You can use the PostScript feature to send a PDF file to the printer
directly for printing.

PDF Files That Can Be Printed

PDF files that can be printed are those created by Adobe Acrobat 4
and Adobe Acrobat 5 (except one part of the features added by PS

1.4).

NOTE

> You may not be able to print some PDF files directly by the

printer due to the way they were created. When this happens,
open the PDF files and use the printer driver to print them.

RINTING VIA ELECTRONIC MAIL

- E-

MAIL PRINTING

When the optional hard disk or compact flash has been installed and
the printer is connected to a network, enabling it to receive e-mails
via TCP/IP communication, e-mails can be sent from the computer
to this printer.

Printing of e-mail contents and TIFF or PDF attachments can be done
from this printer.

This feature may need to be enabled via the webpage under

ARCODE PRINTING

This printer uses standard PCL font selection commands to enable
printing of algorithm generated bar codes.

Benefits:

> Any size barcode generation

> Automatically generates checksums

> Automatically adds stop and start characters

Intelligent barcoding

Unlike some barcode solutions, which merely add fonts to a PC or
printer, this printer actually extends the PCL5 language. Barcode
formatting, error detection and checksum calculation are performed
by the printer, reducing the load on the host and the network.
Barcodes can be printed in almost any size or rotation, bar width and
height. Caption text can be embedded in the bars or printed above
or below the bars in a variety of fonts and sizes.

NOTE

See the Reference Guide for detailed use information.

into the printer.

CAUTION!

Do not place paper over the right width guide.

Do not load paper exceeding the maximum fill line or the
maximum capacity allowed.

Align the right width guide with the paper width
correctly. If the right width guide is not in place, the
paper will not be properly fed and this may cause paper
jams.

The lid of the tray must be firmly closed. If not, the
paper might become misaligned.

8. Depending on the types and sizes of the loaded paper, you

need to configure settings on the control panel. Change the
paper type when non-plain paper such as recycled paper,
heavyweight paper or transparencies are loaded. Configure
the paper size when custom size paper is loaded.

RUM/TONER CARTRIDGE REPLACEMENT

The drum/toner cartridge includes the toner and the photosensitive
drum. A message will appear on the control panel when it is about
time to replace the drum/toner cartridge. If the message indicates
that the printer is still ready to print you should still be able to print
about 200 pages before actually replacing the cartridge, otherwise
you should replace it immediately.

The possible number of pages that can be printed differs according
to factors such as the print contents, paper size, paper type,
environment used, and the frequency of switching on/off the power
of the machine.

If you continue to print with a drum/toner cartridge whose
replacement is long overdue, it may affect the functions of this
machine, such as the print quality. It is recommended to install a
new drum/toner cartridge.

You can set whether to stop printing when the drum/toner cartridge
is due for replacement.

WARNING!

Never expose a drum/toner cartridge to an open flame.
It can cause an explosion and you can be burnt.
