When using this machine, the following safety precautions should always be followed.
Safety During Operation
In this manual, the following important symbols are used:
WARNING:
CAUTION:
Indicates a potentially hazardous situation which, if instructions
are not followed, could result in death or serious injury.
Indicates a potentially hazardous situation which, if instructions are not
followed, may result in minor or moderate injury or damage to property.
R WARNING:
• Do not damage, break or make any modifications to the power cord.
Do not place heavy objects on it. Do not pull it hard nor bend it more
than necessary. These actions could cause an electric shock or fire.
• Disconnect the power plug (by pulling the plug, not the cable) if the
power cable or plug becomes frayed or otherwise damaged.
• To avoid hazardous electric shock, do not remove any covers or
screws other than those specified in this manual.
• Turn off the power and disconnect the power plug (by pulling the plug,
not the cable) if any of the following occurs:
• You spill something into the machine.
• You suspect that your machine needs service or repair.
• The external housing of your machine has been damaged.
• Keep the machine away from flammable liquids, gases, and aerosols.
A fire or an electric shock might occur.
• Connect the power cord directly into a wall outlet and never use an extension cord.
• Only connect the machine to the power source described in this manual.
• Disposal can take place at our authorized dealer or at appropriate collection sites.
1
R CAUTION:
• After you move the machine, use the caster fixture to fix it in place. Otherwise the machine might move or come down to cause an injury.
• If you use the machine in a confined space, make sure there is a continuous
air turnover.
• Keep the machine away from humidity and dust. Otherwise a fire or an electric shock might occur.
• Protect the machine from dampness or wet weather, such as rain and snow.
• Do not place the machine on an unstable or tilted surface. If it topples over,
an injury might occur.
• Unplug the power cord from the wall outlet before you move the machine.
While moving the machine, you should take care that the power cord will not
be damaged under the machine.
• When you disconnect the power plug from the wall outlet, always pull the
plug (not the cable).
• Do not allow paper clips, staples, or other small metallic objects to fall inside
the machine.
• For environmental reasons, do not dispose of the machine or expended
supply waste at household waste collection points. Disposal can take place
at an authorized dealer.
• When disposing of a used ink container, reattach the cap to prevent ink from
splattering.
• Be careful not to get ink on your clothes when replacing an ink container. Ink
stains on clothes are hard to remove.
• Be careful not to cut yourself on any sharp edges when you reach inside the
machine to remove misfed sheets of paper or masters.
• If ink comes into contact with your eyes, rinse immediately in running water.
For other symptoms, consult a doctor.
• Keep the ink or ink container out of reach of children.
• If ink is ingested, induce vomiting by drinking a strong saline solution. Con-
sult a doctor immediately.
• If your skin comes into contact with ink, wash the affected area thoroughly
with soap and water.
• While printing, do not touch the belt at the end of the paper delivery tray or
the job separator. Otherwise, an injury might occur.
• Our products are engineered to meet the high standards of quality and functionality, and we recommend that you only use the expendable supplies
available at an authorized dealer.

Printing Paper
The following types of print paper are not recommended for this machine.
• Paper smaller than 90 mm × 140 mm, 3.6" × 5.6"
• Paper larger than 275 mm × 395 mm, 10.8" ×15.6"
• Paper heavier than 127.9 g/m
• Paper lighter than 35 g/m
• Roughly-cut paper
• Paper of different thickness in the same stack
• Buckled or curled paper
• Low stiffness paper
Correct curls in the paper before setting it in the machine. When you cannot correct the paper curl, stack the paper with the curl face down. Otherwise the paper
might wrap around the drum or stains might appear.
Store paper where it will not curl or absorb moisture. Use paper soon after it is
unpacked.
Only use paper where the leading edge has two right angle corners, as shown
below.

Standard Printing
-Printing
In this manual, the word, “printing”
is used as opposed to “copying” in order to distinguish between the process that your machine uses to make
prints, and the process used by a standard copier machine.
A standard copier scans in the original for each copy set made. This machine, however, scans in your original
once and makes multiple prints from
this master.
This chapter describes the basic printing operations that your machine is
capable of.
A Place the original face down in
the document feeder. Adjust the
original side guides to match the
size of the original.
Standard Printing
B Press the {Master Making} key.
1
A trial print is delivered to the paper delivery tray.
C Press the {Proof} key and check
the image density and image position on the proof print.
Note
❒ You can only place one original
at a time.
Note
❒ If the image position is not cor-
rect, adjust it using the {Image
Position} keys. See p.18 “Adjust-
ing the Print Image Position”.
❒ If the image density is too dark
or too light, adjust the image
density using the {Image Densi-
ty} key. See p.20 “Adjusting the
Print Image Density”.
15
Operation
D Enter the number of prints re-
quired with the number keys.

Note
❒ Up to 9999 prints can be entered
at a time.
❒ To change the number entered,
press the {Clear/Stop} key and
enter the new number.
E Press the {Print Start} key.
16
Note
❒ After printing is completed, the
same number of prints is automatically set for the next job.
❒ To stop the machine during the
multi-print run, press the
{Clear/Stop} key.
❒ To return the machine to the ini-
tial condition after printing,
press the {Clear Modes/Recovery}
key.
After Printing
A Lower the paper feed tray adjust-
ment lever and remove the paper
from the paper feed tray.

Operation
Adjusting the Print Image Position
After master making, you can adjust
1
the print image position to suit your
needs. There are two ways to do this:
❖ Shifting the Image Position Forwards
or Backwards
Adjust the image position using
the {Image Position} keys.
❖ Shifting the Image Position to the
Right or Left
Adjust the image position by shifting the paper in the paper feed
tray.
Shifting the Print Image Position
Forwards or Backwards
Note
❒ When you shift the image for-
wards, leave a margin (more
than 5 mm, 0.2") at the leading
edge. If there is no margin, paper might wrap around the
drum and cause a misfeed.
❒ The right or left {Image Position}
keys shift the image about 1
mm, 0.04" each time they are
pressed. However, the indicator
will only register a change
when the image position is
shifted about 5 mm, 0.2".
B Press the {Proof} key to check the
image position.

ty to suit your needs. There are two
ways to do this:
❖ Before Making a Master
Adjust the image density using the
{Image Density} key.
❖ After Making a Master
Adjust the image density using the
{Speed} key.
Before Making a Master
A Use the {Image Density} key before
pressing the {Master Making} key.
After Making a Master
A Press the {Speed} key to decrease
the printing speed. Press it again
to bring the printing speed back
to Fast.
Note
❒ The faster the printing speed be-
comes, the lighter the printing
density is. If you want darker
prints, decrease the printing
speed.
20
Note
❒ In addition to Normal, Darker
and Lighter modes, you can also
select Tint mode to make halftone prints. When the Lighter
mode indicator is blinking, Tint
mode is selected.
Changing the Printing Speed
Use the {Speed} key to adjust the
speed of the machine to suit the image density and paper type.
A Press the {Speed} key to select the
printing speed.
Note
❒ The following speeds are avail-
able:
•Fast:
90 sheets/minute
•Slow:
60 sheets/minute
❒ The default is 90 sheets/minute.
❒ The faster the printing speed be-
comes, the lighter the printing
density is, and vice versa.
❒ Select the slower speed when
you are printing on very thick
or very thin paper.
