CHAPTER I PRODUCT OUTLINE

1. FEATURES

This printer has the following features:

2400 x 600 dpi Class Resolution

The printer prints pages with a resolution of 600 dots per inch (dpi) as
default. It also provides higher quality printout which is the equivalent
of 2400 x 600 dpi resolution when using HRC or CAPT.

High Speed Color Laser Printing

The printer allows crisp printing in 24 bit brilliant color. The printer
prints at a speed of 16 pages per minute in monochrome mode and 4
pages per minute in full color mode. The controller utilizes a high
speed 32-bit RISC microprocessor and special hardware chips, which
provides a very fast processing speed.

High Resolution Control (HRC)

The high resolution control (HRC) technology provides clear and crisp
printouts and improves even the 600 dpi resolution. This mode is
effective when printing text data.

Color Advanced Photoscale Technology (CAPT)

The printer can print graphics in 256 shades for each color in HP
color printer PCL5C™ and BR-Script level 2 emulations, producing
nearly photographic quality. This mode is effective when printing
photographic images.

®

Maintenance-Free Toner Cartridge

A toner cartridge can print up to 10,000 (Black) and 6,000 (Cyan,
Magenta and Yellow) single-sided pages at 5% coverage. The one
piece, easy-to-replace toner cartridges do not require difficult
maintenance.

Universal Media Cassette

This printer loads paper automatically from the media cassette. Since
the media cassette is a universal type, a number of different sizes of
paper can be used. Even envelopes can be loaded from the media
cassette.

Three Interfaces

This printer has a high speed IEEE 1284 compliant bi-directional
parallel interface, an RS-232C serial interface, and a modular
input/output (MIO) compatible interface.

If the application software supports the bi-directional parallel interface,
you can monitor the printer status. It is fully compatible with the
industry-standard IEEE 1284 bi-directional parallel interface.

The RS-232C serial interface is an industry standard so that you can
connect it to any computer using a standard serial cable.

The MIO interface allows you to install a commercial MIO-compatible
card. If the card is installed, this interface port can be used for
features such as networking or printer sharing.

I-1

Automatic Interface Selection

The printer can automatically select the bi-directional parallel, RS­232C serial, or MIO interface depending on the interface port through
which it receives data. With this feature, the printer can be connected
to more than one computer.

Five Emulation Modes

The printer can emulate Hewlett-Packard Color PCL
monochrome mode) and PostScript
(Brother BR-Script Level 2) printers, the industry-standard HP-GL™
plotter as well as EPSON
(in monochrome mode). It is possible to print with all application
programs that support one of these printers.

Automatic Emulation Selection

The printer can automatically select the printer emulation mode
depending on the print commands it receives from the computer
software. With this feature, many users can share the printer on a
network.

Data Compression Technology

The printer can internally compress the received graphics and font
data in its memory so that it can print larger graphics and more fonts
without additional memory.

Various Fonts

The printer has 75 scalable fonts and 12 bitmapped fonts The fonts
that can be used vary according to the current emulation mode.

CCITT G3/G4

Since the printer supports the CCITT G3/G4 format in addition to HP­compatible formats, it can quickly receive and print data compressed
in this format.

Lock Panel

Power Save Mode

Toner Save Mode

Reprint Function

If the panel button settings have been changed, the printer may not
work as expected. It is possible for the administrator of the printer to
lock the settings to prevent changes from being made.

The printer has a power saving mode. As laser printers consume
power to keep the fixing assembly at a high temperature, this feature
can save electricity when the printer is on but not being used. The
factory setting of the Power Save mode is ON so that it complies with
the EPA Energy Star new specification. Compared with conventional
laser printers, this printer consumes less power even when the power
saving mode is turned off.

The printer has an economical toner save mode. This mode allows
you to reduce the printer running cost substantially in addition to the
improved life expectancy of the toner cartridge.

A touch of a panel button allows reprinting of the last print job without
sending the data again from the computer. When there is not enough
memory to print the last complete job out, the last print page can be
reprinted.

PCMCIA Card Slot

The printer has two PCMCIA card slots (Type II cards: 2 slots
available, Type III cards: 1 slot available). The following cards can be
installed;
