Before Starting to Use
Safety Guide - Installation
This section describes the precautions to be observed when installing the machine. Read this section before install-
ing the machine.
Note:
• Your dealer will help you to determine a proper location for the machine at the time of delivery.
Installation
AWARNING:
• Place the machine on the dedicated stand for this model or on a flat and stable surface (maximum of 10 mm (3/8
inches) differential allowed). Injury might occur if the machine falls.
• Install the machine in a well-ventilated area. Failure to do so may result in serious health problems.
BCaution:
• Install the machine near the electrical outlet to avoid using an extension cord between the machine and the elec-
trical outlet. If an extension cord is absolutely required, do not use one longer than 5m (15 feet).
• Allow at least 10 cm (4 inches) or more of clearance behind the machine so that you can unplug the machine in
case of technical difficulties.
• Keep the machine away from dusty environments. Failure to do so may result in fire.
Important!:
• Avoid installing the machine in the locations listed below. Failure to observe this precaution may lead to machine failure.
• Locations with exposure to direct sunlight, such as locations close to windows (Curtain all windows that might expose the
machine to direct sunlight)
• Locations that are subject to sudden changes in temperature
• Extremely hot and humid locations or cold and dry locations
• Heated locations
• Locations exposed to direct cold air, direct hot air, or direct radiant heat
• Locations of poor permeability and ventilation
Power connection
AWARNING:
• Do not overload the electrical outlet or extension cord, nor damage the power cord by placing heavy objects on it
or pulling or bending it. This can result in fire or electric shock.
• Do not pull the power cord but hold the plug itself when unplugging it. This can damage the cord and result in fire
or electric shock.
• Do not plug or unplug the power cord if your hands are wet. This can result in electric shock.
BCaution:
• Pull out the power cord plug from the electrical outlet more than once a year and clean the prongs of the plug and
their surroundings. Dust collected on these areas can result in fire.
Important!:
• Check the power cord and plug for poor connections. Plug the power cord securely into a nearby electrical outlet.
• Be sure to turn off the POWER switch when connecting or disconnecting a cable.

Before Starting to Use

Important!:
• Operate the machine under the following appropriate environment conditions.
Temperature range: 15°C to 30°C (59°F to 86°F)
Humidity range: 40% to 70% (noncondensing)
Machine Handling
AWARNING:
• Do not place water containers or metallic objects on the machine. Fire or electric shock may occur if water or metal-
lic objects fall into the machine.
• Do not use combustible spray and flammable solvent near the machine.
If sprayed gas and flammable solvent contact electronic components inside the machine, fire or electric shock
might occur.
• Do not insert any metallic material or flammable substance into the machine through any opening. This can result
in fire or electric shock.
• Do not remove machine covers. Exposing internal parts may result in electric shock.
• Do not disassemble or rebuild the machine by yourself. This can result in fire or electric shock.
• If the machine emits excessive heat, smoke or foul odor, immediately turn off the POWER, unplug the power cord
and contact your service representative. Failure to do so can result in fire or electric shock.
• If something drops inside the machine, immediately turn off the POWER, unplug the power cord and contact your
service representative. Failure to do so can result in fire or electric shock.
• Never stick your hands or fingers in the openings of the machine during operation.
• Keep loose clothing or long hair away from moving parts to avoid becoming entangled.
• Do not place heavy objects on the machine. The objects might fall and cause injury.
• Contact your service representative before moving the machine.
BCaution:
• Never insert fingers, etc. into the openings around Paper Feed Tray and Paper Receiving Tray. This can result in
injury.
• Because ink may have stuck to areas around the Print Drum (Cylinder) or inside the machine when the Print Drum
(Cylinder) was removed, be careful not to contact them with your hands or clothes.
When ink has stuck to your hands, etc., wash it off with detergent as soon as possible.
• When you remove paper by inserting a hand inside the machine, be careful not to touch the paper separation hook.
Because the tip of paper separation hook is sharp, it might cause injury.

and open the two inner Paper Arrangers. )p.37, )p.38
• When using slippery paper, set the Paper Feed Pressure Adjustment Lever to “CARD” ( ). )p.37, )p.38
• Use flat printing paper that is free of folds. If curled paper is unavoidable, place the printing paper so that the curl
faces down.
• Paper may stick to the Print Drum (Cylinder) surface if the top margin is too narrow on the original or if the upper
portion of the original uses a large amount of ink. To solve this problem, lower the print position to provide a wider
top margin or reverse the top and bottom of the original. Then restart printing from the beginning.
Storing Environment
Store printing paper in a level, dry area. Storing the paper in an excessively humid area can result in paper jams or
poor print quality.
After unpacking printing paper, keep the remaining paper wrapped and store it in a moisture-proof box. It is highly rec-
ommended to put silica gel in the paper storage box.

Size and Weight Restrictions
Usable originals are as follows.
* The paper weight limit differs depending on which sides of the original are scanned. Scanning sides can be speci-
fied using “Scanning Side -ADF”. )p.158
• Originals are scanned according to the size of paper placed on the Paper Feed Tray when masters are made; for
the same width, the positions of the Feed Tray Paper Guides.
When the placed paper is smaller than an original, not the entire original will be scanned.
When the placed paper is larger than an original, dirt on the glass or shade of the original, for example, may result
in unexpected dirt in the area beyond the size of the original.
• Bound originals can also be used on the Glass Platen.
• You can feed automatically up to 50 original sheets 80 g/m2(21-lb bond) when using the optional ADF (Auto Doc-
ument Feeder) unit.
Note:
• Use the Glass Platen when printing the following originals:
– Patched or worn originals
– Wrinkled, curled, folded, or torn originals
– Transparent originals (such as tracing paper or OHP transparencies)
– Chemically treated originals (such as thermal or carbon paper)
– Originals with correction fluid or glue
– Extremely thin originals
Using the optional Auto Document Feeder AF-VI: less than 50 g/m2(13-lb bond)
Using the optional Auto Document Feeder DX-1:
less than 40 g/m2(11-lb bond) (Front Side -> Simplex) / less than 52 g/m2(14-lb bond) (Duplex -> Simplex)
– Extremely thick originals
Using the optional Auto Document Feeder AF-VI: greater than 128 g/m2(34-lb bond)
Using the optional Auto Document Feeder DX-1:
greater than 128 g/m2(34-lb bond) (Front Side -> Simplex) / greater than 105 g/m2(28-lb bond) (Duplex -> Sim-
plex)
– Heavy drawing paper
– Originals with staples or clips
• If an original is wrinkled, curled, or creased flatten it thoroughly so that the originals can be pressed directly onto
the Glass Platen during processing.

• If correction fluid or glue is used on an original, thoroughly dry it before placement.
• For an original patched with thick paper, the shade of the patched paper may also be printed.
Maximum Printing Areas and Margins
The maximum printing areas are as follows.
Important!:
• Even when paper of the maximum size (320 mm ×432 mm (1210/16" ×17")) or Ext.Paper (top-bottom length up
to 555 mm (2114/16")) is used, printing is performed within the maximum printing areas mentioned above.
• Regardless of the size of the original, the printing area is decided by the paper size set in the Paper Feed Tray. The
printing area is the printing paper size excluding the margins shown in the figure below. The original needs to be
prepared with advanced consideration for the margins.
Materials Not to Be Printed
Do not use the machine in any manner which violates the law or infringes on established copyrights, even when mak-
ing copies for personal use. Consult your local authorities for further details. In general, use discretion and common
