Fluidized waste treatment system
using natural purification
At the Fukuyama site where ICs are manufactured, we used to
hire a subcontractor to incinerate spent developer, which
makes up 70% of all our industrial waste. This method placed a
significant burden on the environment, including the energy
used for incineration and exhaust gas from the vehicles
transporting the waste. Treatment costs swelled as production
increased. It was a challenging issue for us, from both an
environmental and managerial standpoint.
We at the Fukuyama site had been pursuing in-house
treatment for spent developer, and we finally completed a
fluidized waste treatment system using natural purification in
1996.
This system is based on a concept of purifying spent
developer by natural processes. Built according to our
proprietary design, it is a state-of-the-art system that produces
no hazardous sludge during the treatment process.
Microorganisms Purify Water, Sustain
Monitoring by Fish
In-House Treatment of Used Developer to
Produce No Polluted Mud
Sharp’s system makes the maximum use of materials existing
in nature. In the microorganism treatment process,
microorganisms cultured to high levels of density are used to
decompose most of the main components in spent developer
that have strong alkalinity.
In the oyster shell treatment process, neutralizing treatment is
carried out using a film of microorganisms that forms on the
surface of oyster shells to decompose other organic
substances.
In the Bincho charcoal/bio-activated charcoal treatment
process, charcoal agents absorb a slight amount of the
remaining organic substances. The charcoal is cleansed
automatically, as the absorbed organic substances are treated
by microorganisms growing on the surface of the charcoal.
In the fish monitoring process, in addition to measuring
instruments, water safety is monitored with freshwater fish,
such as roaches and Japanese bitterlings, which are sensitive
to environmental changes.

Effective use of water at Mie site
Making the Most Effective Use of Water Resources
Recovery effluents with a reuse rate of 92%
Special Edition
2
Our Mie plant is located 10 km southeast of Matsuzaka City in
Mie prefecture. The nearby Kushida River is the source of
drinking water for Matsuzaka citizens and is also used for local
agricultural irrigation. Since LCD manufacturing requires a lot
of water, drainage treatment is an important factor in
environmental preservation in the neighborhood.
Effluent Treatment Facility Ensures Reuse
Rate of 92%
Clear Concept for Environmental
Preservation
Pure water used in the production process is classified into
inorganic, organic and neutral effluents* before being
discharged and recovered in a closed system for later reuse.
When we began operations in 1995, we mainly recovered and
reused inorganic effluent, which was believed to have a
negative effect on the environment with a recovery rate of
30%. We had repeatedly evaluated treatment processes to
recover and reuse organic and neutral effluents until 1996
when we introduced a new treatment process. This process
utilizes microorganisms for the organic effluent and
ultraviolet-ray oxidation treatment technology for the neutral
effluent. This raised the recovery rate to 69%.

Quick First Copy Time
The AR-M451U/N has a quick first copy time of 4.4
seconds to save valuable time when performing
multiple short-run jobs.
Super-Efficient Output
With a continuous output of 45 cpm/ppm*, the
AR-M451U/N allows you to produce large-volume
documents in less time.

High-Speed Processor
The AR-M451U/N comes with a high-speed RM7065
64-bit RISC processor (300 MHz), which allows even
memory-intensive graphic documents to be processed
promptly and ensures speedy and efficient printing in the
networked office.
A3 Duplex Single Pass Feeder (DSPF)
The AR-M451U/N can be
equipped with an optional DSPF,
which scans both pages of
two-sided documents up to A3
(11" x 17") in size in one pass.
Doing away with the reversing
circuit minimises paper misfeeds and vastly improves reliability.
With a quick scanning speed of 60 pages per minute for two-sided
originals and 37 pages for single-sided in Standard mode, the
AR-M451U/N finishes even large projects quickly.
Duplex Copying/Printing
The AR-M451U/N can make
two-sided copies and
printouts when equipped with
the optional duplex module or
duplex module with bypass tray,
effectively reducing paper costs
as well as saving filing space. Duplex copying is even more
productive when used together with the DSPF.
Superb Image Quality
You get ultra-detailed reproduction with 600 dpi resolution. The
printing resolution can be enhanced to 1,200 dpi (with
smoothing). Digital Auto Exposure Control provides optimum copy
contrast, and Text/Photo mode automatically adjusts the copy
contrast for documents containing both text and photos.
Network Tandem Function
When two AR-M451U/Ns are connected to the same office
network, you can use both simultaneously to double
copying/printing output to up to 90 cpm/ppm. Operation is
simple and the machines can even be in different locations. With
just a few keystrokes, you can handle large-volume jobs to meet
tight deadlines.
Job Build for Large-Volume Scanning
The AR-M451U/N easily handles copy jobs exceeding the DSPF’s
50-sheet capacity*

. Large-volume documents of up to 10,000
pages*

are automatically stored on the AR-M451U/N’s hard disk
so that users can print all documents at once at a later time.

number of pages that can be saved for the Job Build function depends on
the AR-M451U/N’s memory capacity and other conditions.
Automated Job Finishing
The AR-M451U/N makes it easy to create
professional-looking documents
automatically. The optional Saddle Stitch
Finisher folds and staples sets of
documents to make completed booklets. A
Finisher is also available for jobs that
require only simple sorting and stapling.
And, a Punch Module allows you to punch
holes in documents for easy filing. These
high-performance finishing capabilities save
you valuable time and money by reducing
costly outsourcing.
Bypass Printing
When conventional printers run out of the paper needed for a
specific job, the machine stops until it is reloaded. With the
AR-M451U/N, however, you never need to wait on someone else’s
job; the AR-M451U/N automatically proceeds to the next
possible job in the queue.
Mail Bin Stacker
The optional Mail Bin Stacker is ideal for
offices where large groups of people
use the same machine. When printing,
avoid mixing up your documents with
those of other users by pre-selecting
one of seven destination bins for
your documents.
Convenient Copy Applications
• Book Copy is convenient for
compiling copies of a book or
bound originals into pamphlet
format.
• Card Shot enables one-touch
copying of both sides of a card
(credit cards, ID cards, etc.)
onto a single page.
• Stamp labels your copy with
entered text, page numbers,
the date, or a reverse character
set such as “CONFIDENTIAL”.
Various Printing Functions
• With PDF/TIFF Direct Print, you save valuable time by printing
PDF and TIFF files without using the printer driver or opening
applications: you can print the file directly from an FTP server
(pull print), a Web page (push print), or an e-mail attachment.
Note: Direct PDF printing requires the optional AR-PK6. Certain types of
TIFF and PDF files may not print out this way.
• Carbon Copy Print mode
automatically outputs multiple
printouts of the same data on
plain and/or coloured paper
from different paper trays.
Convenient for multi-print
invoices and purchase orders.
• Proof Printing allows you to check a trial set before printing out
in large numbers to avoid printing mistakes.
• Barcode font compatibility
(with the optional AR-PF1 Barcode Font Kit)
Productive Copying and High-Performance Network Printing
Note: Network print function is standard on the AR-M451N, but the AR-M451U requires the optional AR-NC7 or AR-NC8 Print Server Card.
Large Paper Capacity
For large-volume jobs and a
wider selection of available
paper sizes, the AR-M451U/N
can accommodate optional
paper drawers for an on-line 4-
way paper feed with a capacity
of up to 3,100 sheets. When a
tray runs out of paper, the Auto Tray Switching function
automatically switches to another paper tray filled with the same
size paper. This allows you to do extra-large volume jobs without
worrying about running out of paper.
PCL6 and PostScript 3 Emulation
The AR-M451U/N supports PCL5e and PCL6 printer languages. For
compatibility with PostScript 3, the AR-PK6 PS3 Expansion Kit is
available.
Powerful Network Printing
The AR-M451U/N works as a network printer with the most
commonly used network operating systems and protocols and
even in mixed network OS environments. With a 64-bit, 300 MHz
CPU, you get powerful network printing via 100Base-TX and
10Base-T Ethernet standards.
Priority Printing
In Job Status mode, the operation panel displays a list of all jobs,
whether printing, copying, scanning, or faxing. See at a glance
which job is in progress and where your job is in the queue. You
can also change the print queue order with one touch of the
LCD screen. Urgent jobs can
receive priority, meaning you
don’t have to wait until other
jobs are finished.
COPYING AND PRINTING
Producing high-volume jobs with amazing speed, simplicity, and superb image quality, the AR-M451U/N’s high-speed RISC processor, productivity-
enhancing options, and advanced printing functions make even complex jobs with sophisticated finishing options efficient and easy.
