220 - 240 VAC (Range 198 - 264 VAC)
Frequency: 50/60 Hz ± 2%
Note
If the power supply is unstable, use a voltage regulator.
The maximum power consumption of this printer is
1400 W. Ensure that the power supply is sufcient to
operate this printer.
We do not guarantee operation where an uninterruptible
power system (UPS) or inverter is used. Do not use an
uninterruptible power system (UPS) or inverter.
WARNING
There is a risk of getting
an electric shock and/or
causing re.
Be sure to turn off the power supply switch when
attaching or removing the AC cable and earth wire.
Be sure to connect an earth wire to the grounding
terminal of exclusive use.
Please do not connect with the ground of a water pipe,
a gas pipe, and a telephone wire, and a lightning rod by
any means.
Make sure to connect with the ground terminal before
connecting the power cord to the power supply plug.
Be sure to plug in and unplug the AC cable while holding

Do not connect this printer and other electric products
to the same wall socket. If it connects simultaneously
with an air conditioner, copier, shredder, etc. Especially,
a printer may incorrect-operate by the electric
noise. When you connect with the same wall socket
unavoidably, please use a commercial noise lter or a
commercial noise cut transformer.
Use the attached power cord and insert it directory with
the ground terminal. Do not use the power cord for
other product for the printer.
Do not use an extension cord. When you use it
unavoidably, use the thing more than rated 15 A.
Use of an extended code may not operate a printer
normally by AC voltage descent.
During printing, do not shut off a power supply or do not
pull out a power supply plug.
When you use it neither for consecutive holidays nor a
travel for a long time, pull out a power cord.

The wireless LAN (AP mode) connects directly
to a wireless terminal (computer, tablet,
smartphone, etc.) without using a wireless LAN
access point.
Note
You cannot enable wireless LAN (infrastructure) and
wireless LAN (AP mode) at the same time.
Do not place any devices (especially microwave
ovens or digital cordless telephones) that emit weak
electromagnetic waves near the machine.
Wireless connections may be difcult if there is any
metal, aluminum framed windows, or reinforced concrete
walls between the machine and the wireless terminal
(computer, tablet, smartphone, etc.).
Wireless LAN connections may have slower transmission
speeds than wired LAN or USB connections, depending on
the environment. We recommend using a wired LAN or a
USB connection.
Preparing to use the wireless LAN
(AP mode)
The machine becomes a simple wireless access
point, and wireless terminals (computer, tablet,
smartphone, etc.) can connect directly to it.
Before you start, conrm that the wireless

:
Paper that meets the conditions for plain paper.
An ink used for a part printing is heat resistant (230°C).
Note
When specifying a printing area, please take into account the differences of printing position as followings:
Print start position: ±2 mm, Paper skew: ±1 mm/100 mm, Image stretch: ±1 mm/100 mm
(when paper ream weight is 70 kg)
This printer cannot print on an ink.
Use paper that meets the following conditions*
2
:
A pigment or an ink used to color paper is heat resistant (230°C).
Paper that has same characteristics with light paper and used for an electronic photo printer.
Paper Recommendations
Your printer will handle a variety of print media,
including a range of paper weights and sizes.
This section provides general advice on choice of
media, and explains how to use each type.
The best performance will be obtained when
using standard 75 - 90 g/m
2
paper designed for
use in copiers and laser printers.
Use of heavily embossed or very rough textured
paper is not recommended.
Pre-printed stationery can be used, but the ink
must not offset when exposed to the high fuser
temperatures used in the printing process.
CAUTION
Envelopes should be free from twist, curl or
other deformations. They should also be of the
rectangular ap type, with glue that remains
intact when subjected to hot roll pressure fusing
used in this type of printer. Window envelopes are
not suitable.
Labels should also be of the type recommended
for use in copiers and laser printers, in which the
base carrier page is entirely covered by labels.
Other types of label stock may damage the printer
due to the labels peeling off during the printing
process.

4. Maintenance
This chapter explains how to replace consumables and maintenance units, clean the printer, and move
or transport the printer.
Replacing Consumables and Maintenance Units
This section explains how to replace consumable items.
WARNING
Do not throw the toner or
toner cartridge into the re.
Doing so may cause toner
splashes leading to burns.
Do not keep the toner
cartridge in places close to
the re. It may catch the
re, which cause re and
burns.
Do not vacuum spilled toner
powder. If vacuuming, it may
cause ignition due to the
sparks from electric contacts.
Toners spillage on the oor
should be wiped off by wet
clothes.
CAUTION
There are high temperature
parts in the device. Do
not touch the periphery
of the label "Caution High
Temperature", which may
cause burns.
Keep the toner cartridge out
of reach of young children. If
young children swallow toner
powder, follow the doctor's
direction immediately.
If toner powder is inhaled,
gargle with large amounts of
water and move the person
to the open area for fresh air.
Follow the doctor's direction
if necessary.
If the toner powder sticks to
your skin like your hands,
wash with soap.
If the toner gets into the
eyes, ush with plenty of
water immediately. Follow
the doctor's direction if
necessary.
If you swallow toner powder,
take large amounts of water
to weaken the toner. Follow
the doctor's direction if
necessary.
When handling a paper
jam, or replacing the toner
cartridge, make sure not to
get your cloth and hands
dirty. When toner powder
stains on your cloth, wash
with cold water. If you wash
with hot water, the toner
may be soaked into the
cloth; it may be difcult to
clean.
Do not disassemble the toner
cartridge. Toner powder may
y upward, and you may
inhale the toner powder
or may get your cloth and
hands dirty.
Keep a used toner cartridge
in a bag so that the toner
powder can not y upward.
Note
Use only genuine Oki Data consumable items to ensure optimum quality.
Service for problems due to use of consumable items other than genuine OKI consumables will incur fees even in the warranty
period or the maintenance contract period.

Replacing Toner Cartridges
Note
Toner powder may spill if you remove a toner cartridge
before the toner runs out.
Life Span of Toner Cartridge
When the “%COLOR% Toner Low” message
(“%COLOR%” indicates C (cyan), M (magenta),
Y (yellow) or K (black)) appears on the display
screen, prepare a replacement toner cartridge.
You can keep printing several hundred pages
until the next message appears.
The number of pages that can make prints
depends on the usage.
When the “%COLOR% Toner Empty” appears
and printing is stopped, replace the toner
cartridge.
Memo
Even if the cyan (blue), magenta (red) or yellow toner
cartridges run out, you can print in black and white by
selecting [Monochrome] or [Grayscale]. However,
please replace the toner cartridge quickly after it runs
out, as not doing so may cause the image drum to be
damaged.
Note
The actual life of the toner cartridge differs depending on
the usage.
Note
Have a new print cartridge ready, as the print quality
declines after more than one year following breaking the
seal.
If you replace the toner cartridge/image drum while it is
being used, the amount of toner used will not be counted
normally.
By opening and closing the output tray after the message
Color toner has run out” is displayed, you are able
to print approximately 100 copies of A4 size ISO test
patterns (approximately 20 pages, ve times). However
further printing operations will not be possible after that.
Please replace the toner cartridge as failure to do so may
damage the image drum.
Procedure for Replacement
(for K (black) Toner Cartridge)
Memo
When replacing the C, M, Y toner cartridges, refer to
“Procedure for Replacement
(for C (cyan), M (magenta),
