NOTICE TO USER
In an effort to meet the demands of a rapidly changing technology, the
manufacturer is continually developing new features and functions to meet your
changing printing or printer needs. As a result, this manual may not exactly reflect
future changes made to the product. Please be sure to consult all manual updates
or addenda when using this product’s documentation.

Using the Copier Properly
To ensure the optimum performance of the copier, follow the precautions listed below.
• Never place a heavy object on the copier.
• Never subject the copier to shocks.
• Never open any doors or turn the copier off while the copier is making copies.
• Never bring any magnetized object near the copier.
• Never use flammable sprays, liquids or gases near the copier.
• Never modify the copier, as a fire or electrical shock could result.
• Never remove any panel or cover which is secured. The copier contains high voltage
components which can cause electrical shock.
• Never tamper with the laser mechanism in laser-equipped models, as blindness or
other injury may result.
• Never drop paper clips, staples or other small pieces of metal through the vents or
other openings in the copier, as a fire or electrical shock can result.
• Never place containers of liquid on the copier. If liquids get inside the copier, they can
cause fire or electrical shock. If a piece of metal or any liquid gets inside the copier,
immediately turn the copier off, unplug the power cord and call your technical
representative. A fire or electrical shock can result if the copier remains plugged in or
is operated after metal or liquid gets inside.
• Never leave the copier running if it becomes unusually hot, or if smoke or an unusual
odor or noise is detected. Should any of these conditions occur, immediately turn the
copier off, unplug the power cord and call your technical representative. A fire or
electrical shock can result if the copier remains plugged in under any of these
conditions.
• Always insert the power plug all the way into the outlet.
• Always make sure that the outlet is visible, clear of the copier or copier cabinet.
• Always provide good ventilation when making a large number of continuous copies.
• Never pull on the power cord, and always hold the plug when unplugging the power
cord. A damaged cord could result in a fire or cause an electrical shock.
• Never unplug the power cord with a wet hand, as it could cause an electrical shock.
• Always unplug the power cord before moving the copier. Moving the copier with the
power cord plugged in can damage the cord resulting in a fire or causing an electrical
shock.
• Always unplug the power cord when the copier is not going to be used for a long time.
• Never place a heavy object on the power cord, or pull or bend it, as a fire or electrical
shock can result.
• Always ensure that the copier does not sit on or roll onto the power cord or
communications cable of other electrical equipment, as malfunctioning equipment or
a fire could result.
• Always ensure that the power cord or communications cable of other electrical
equipment does not become wedged into the copier mechanism, as malfunctioning
equipment or a fire could result.
• Always use the correct power voltage, as improper voltage can cause a fire or
electrical shock.

Using the Copier Properly
•Never use a multiple outlet adapter, as a fire or electrical shock can result.
•Should the power cord become damaged, immediately turn the copier off, unplug the
power cord and call your technical representative. A damaged cord can result in a fire
or cause an electric shock.
•If an extension cord is needed, use one with a greater rated capacity than the
maximum power requirements of the copier. The use of an extension cord that falls
short of supporting the maximum power requirements can result in overheating or a
fire.
•Always unplug the copier whenever anything unusual is observed during operation.
Make sure that the outlet is nearby and clear of the copier and furniture.
•Never touch the electrical contacts inside the right door and underneath the Imaging
Unit, as an electrostatic discharge may damage the copier.
=Locate the Copier in a Well Ventilated Room=
A negligible amount of ozone is generated during normal operation of this copier. An
unpleasant odor may, however, be created in poorly ventilated rooms during extensive
copier operations. For a comfortable, healthy and safe operating environment, it is
recommended that the room be well ventilated.
=Placer le copieur dans une pièce largement ventilée=
Une quantitéd’ozone négligeble est dégagée pendant le fonctionnement du copieur
quand celui-ci est utilisénormalement. Cependant, une odeur désagréable peut être
ressentie dans les pièces dont l’aération est insuffisante et lorsqu’une utilisation
prolongée du copieur est effectuée. Pour avoir la certitude de travailler dans un
environnement réunissant des conditions de confort, santéet de sécurité, il est
préférable de bien aérer la pièce ou se trouve le copieur.

Terms and Symbols for the Type of Originals and Copy Paper
A few special terms and symbols are used in this manual to designate types of originals and copy paper.
This page explains about these terms and symbols.
Feeding Direction (copy paper path)
In this copier system, copy paper is taken up from the right-hand side of the copier, fed through the copier
toward the left-hand side, and ejected face down onto the Copy Tray. In the figure below, the direction in
which the copy paper is fed, as indicated by the arrow, is called the “feeding direction.”
“Width” and “Length”
Terms and Symbols Used
1166O216AC
1139O1610A
When we talk about the size of the original or copy,
we call side A “width”and side B “length.”
A: Width
B: Length
1139O1610A
<Lengthwise >
When the original or copy has a “length”longer than
its “width,”we call it “lengthwise”and use symbol
“L”or “.”
1139O1620A
<Crosswise >
When the original or copy has a “length”shorter
than its “width,”we call it “crosswise”and use
symbol “C”or “.”

Safety Information
Laser Safety
This is a digital machine which operates by means of a laser. There is no possibility of danger from the
laser, provided the machine is operated according to the instructions in this manual.
Since radiation emitted by the laser is completely confined within protective housing, the laser beam
cannot escape from the machine during any phase of user operation.
This machine is certified as a Class 1 laser product. This means the machine does not produce hazardous
laser radiation.
Internal Laser Radiation
Maximum Average Radiant Power: 36.7 (µW) at the laser aperture of the print head unit.
Wavelength: 770-810 nm
This product employs a Class 3b Laser Diode that emits an invisible laser beam.
The Laser Diode and Scanning Polygon Mirror are incorporated in the print head unit.
The print head unit is NOT A FIELD SERVICE ITEM.
Therefore, the print head unit should not be opened under any circumstances.
For the United States
CDRH regulation
This copier is certified as a Class 1 Laser product under the Radiation Performance Standard according to
the Food, Drug and Cosmetic Act of 1990. Compliance is mandatory for Laser products marketed in the
United States and is reported to the Center for Devices and Radiological Health (CDRH) of the U.S. Food
and Drug Administration of the U. S. Department of Health and Human Services (DHHS). This means
that the device does not produce hazardous laser radiation.
The label shown on page viii indicates compliance with the CDRH regulations and must be attached to
laser products marketed in the United States.
This is a semiconductor laser. The maximum power of the laser diode is 5mW and the wavelength is 770-
810nm.
