DFC 800 –
The colour laser copier

With the 6

starpro

Develop has crea­ted a concept which is ideally suited
to the needs and requirements of the
user; a way to achieve higher produc­tivity, greater ease of use and a wide
range of functions for a wide variety of
applications. This concept is also the
basic principle of the DFC 800, the
new full-colour laser copier system.
The DFC 800 is capable of far more
than simply producing colour copies
of outstanding quality. At the touch of
a button, a clear, interactive user
touch-screen guides you intuitively to
the end result while practical func­tions such as the automatic paper for­mat selection (APS) and auto original
type selection save you tedious pre­setting work.
Whether you urgently need to produ­ce a presentation brochure in colour
or to change a draft, whether you
need to have several copies of docu­mentation printed or, you simply want
a copier which combines the advan­tages of a black and white copier with
those of a colour copier and which
can also be used as a multi-functional
colour laser printer: The DFC 800
offers just the right solution for any
copying tasks which may arise in your
office. Here are just a few of the bene­fits:

Outstanding image
reproduction

By regulating the laser intensity, the
“Laser Intensity Modulation System”
used by Develop ensures that image
reproduction is more precise and has
higher contrast. Other innovative fea­tures such as digital development,
automatic adjustment, small toner
particles, a new image stabilisation
system, colour balance and colour
variations facilitate excellent quality,
superb colour graduations and crystal
clarity and sharpness.

Wide range of media

The new DFC 800 combines high
image quality with great media flexibi­lity too. Media fom A6 to A3 full bleed
can be fed up to 209 g/m

in weight.

Easier to maintain

Thanks to the modern modular con­struction system, preventative main­tenance requires a minimum amount
of time. All consumables and expen­dable components can be effortless­ly removed from the front or the side
unit and replaced so that the design
of the DFC 800 is in line with the
user-friendly requirements of our
6starpro philosophy.

User-friendliness

The DFC 800 is as user-friendly as it
is versatile. All the functions required
for carrying out even highly complex
tasks without difficulty are clearly laid
out before you: the interactive touch­screen and a keyboard for inputting
figures directly. And you can save on
time and materials by making fine­colour adjustments in colour test
mode. As many as seven different
colour variations can be tested on a
single A4 sheet for you to choose
from.

Higher productivity

Thanks to the comprehensive perfor­mance range of the DFC 800, you
can choose from a range of system
options in order to increase produc­tivity even further: For example, addi­tional functions such as the automatic
feeding of originals, stapling, sorting
and fully automatic duplexing for
double sided copies and prints.

Environmentally friendly

In addition to its compact design, the
DFC 800 has a number of environ­mentally and office friendly features
such as low noise operation, an extre­mely efficient ozone filter and a recyc­ling system for the fusing oil.

Why DFC 800 colour copies
look so natural to the
human eye

If you want colour copies which are
as crystal clear and sharp as your
originals, you should take a closer
look at the DFC 800.

It’s highly developed LIMOS (Laser
Intensity Modulation System) tech­nology has set a high standard.
Changes in the colour tones are
reproduced in greater detail than

with conventional systems. Colour
shades interact so naturally in the
copy that they are barely distinguis­hable from the original.

Screen LIMOS III
technology

The full-colour technology used in the
DFC 800 represents a new generation
of laser intensity modulation systems
(LIMOS).
With the new Screen LIMOS III, a
laser beam, with an extremely small
diameter, is used and this provides a
resolution of 600 dpi by 400 dpi.
The DFC 800 offers finer screening,
more stable grey scales and higher
resolution than its predecessor. The
so-called moiré patterns have largely
been eliminated and the colour gra­dations have been improved.

Screen angling

The DFC 800 makes use of the fact
that grey scales are displayed better
in diagonal, rather than horizontal or
vertical lines. Owing to the screen
angling, a diagonal dot pattern or
“screen angle” is created and the
undesirable dot patterns are avoided
by shifting the screen dot centres.
The result: multi-colour printouts of
the highest quality.

Accuracy to a 1/

4

of a

pixel

By automatically adjusting the laser’s
intensity, the DFC 800 is able to
reproduce sharp, crystal clear lines
and edges. The DFC 800 also ensu­res excellent screening and first class
colour gradations when reproducing
any kind of document.
In combination with the new FEET
system (Fine Edge Enhancement
Technology) text is printed at a calcu­lated resolution of 1800 x 600 dpi.
This makes the edges of the letters
sharper.
And furthermore, with the aid of the
laser intensity, it is possible to produ­ce 256 grey scales per quarter dot.

Innovative development
unit

The DFC 800 has newly designed
development units which ensure even
distribution of the toner on the drum
while also prolonging the life of the
consumables. With special pre­magenetisation, a roller system with
two magnets ensures stable toner
distribution on the photoconductor
drum. Clear, faithful reproduction and
outstanding area coverage are gua­ranteed.

Reproduction quality

Even in the case of very large copying
jobs, the innovative image stabilisa­tion system ensures uniform copy
quality. Sensors continuously monitor
the amount of toner remaining and
the photoconductor drum loading. A
32-bit processor analyses this data
and regulates any changes needed.

Better black and white
copies

When copying black and white docu­ments, you get a deep, saturated
black with the DFC 800, thanks to the
automatic image blackening control.
Its improved area recording system
reduces possible moiré patterns and
also ensures that you get the best
possible quality. The result: better text
and black and white reproduction of
remarkable quality.

Conventional system:
The laser diameter is the same size as
a screen dot.

Screen LIMOS technology:
The DFC 800’s precision laser is the
size of just a quarter of a screen dot.
