tions against heat and dust, causing some troubles.
C. Power source (Capacity, voltage, frequency,
safety, plug)
If the power specifications are not satisfied, the machine cannot
exhibit full performances and may cause safety trouble.
Strictly observe the following specifications.
Strictly observe the following specifications.
(1) Power capacity
The power capacity must conforms to “3. Power configuration A.

(An electrical work is required.)
Use of a step-up transformer is also available. In this case, the
capacity must be great enough for the max. power consumption of
the machine.
(3) Power frequency, waveform
The frequency must be within the range of the specified frequency
+/-2%. If power waveform is deformed, a trouble may occur.
(4) Safety
Be sure to properly ground the machine.
Grounding (earth connection) must be performed before inserting
Grounding (earth connection) must be performed before inserting
the power plug into the power outlet.
When disconnecting the earth connection, be sure to disconnect
When disconnecting the earth connection, be sure to disconnect
the power plug from the power outlet in advance.
(5) Power plug
Check the shape of the power plug of the machine, and insert it into
a power outlet of the acceptable shape.
Power plug stated in power capacity.
D. Floor strength and level
This machine is considerably heavy and becomes heavier with an
option installed.
The floor must be strong enough to safely support the weight of the
The floor must be strong enough to safely support the weight of the
machine as well as any installed options.
If the unit is not horizontally installed, the toner density control is not
If the unit is not horizontally installed, the toner density control is not
performed normally, degrading the copy quality.
If not, color shift or image distortion may occur.
If not, color shift or image distortion may occur.
To assure proper Image quality, make sure the machine is setting
level.
E. Direct rays of the sun, dust, temperature,
humidity, gasses, chemicals, vibration
(1) Temperature and humidity (Environmental
conditions)
This machine is designed to perform properly under the specified
temperature and humidity. If the temperature and humidity exceeds
the specified range, the machine may not operate properly and or
cause equipment failure.
Especially when the humidity is too high, paper absorbs humidity to
Especially when the humidity is too high, paper absorbs humidity to
cause a paper jam or dirty copy.
Do not install the machine near a heater, a cooler, or a humidifier.
Do not install the machine near a heater, a cooler, or a humidifier.
Condensation may form inside the machine causing multiple trou-
bles. Use enough care for ventilation.
No.

(2) Contaminates
If dust enters the machine, it may cause dirty copy and a paper
jam, resulting in a shortened lifetime.
(3) Direct sunlight
If the machine is installed under the rays of the sun, the exterior of
the machine may be discolored and abnormal copies may be pro-
duced.
(4) Gases and chemicals
Do not install the machine at a place where there are gases and
chemicals. Especially be careful to avoid installation near a diazo-
type copier, which produces ammonium gas.
Copy quality may be adversely affected and a trouble may be

deflected and a trouble may be caused.
F. Note for handling PWB and electronic parts
When handling the PWB and the electronic parts, be sure to
observe the following precautions in order to prevent against dam-
age by static electricity.
> When in transit or storing, put the parts in an anti-static bag or
> When in transit or storing, put the parts in an anti-static bag or

3. Power configuration
A. Indoor wiring (power outlet) and breaker information
NOTE:
> Prepare an indoor wiring (power outlet) which is connected to the AC plug of the machine and its option units.
> Prepare an indoor wiring (power outlet) which is connected to the AC plug of the machine and its option units.
The required number of power outlets varies according to the combination of the option units.
Prepare the necessary number of them.
Example: (North America) Finisher "2.9A", large-capacity multi-stage tray "8A" 12A>10.9A=2.9A+8A Connectable to the same circuit
(breaker).
> For the AC cord of an option unit, use another indoor wiring (another breaker) than that for the machine.
For North America only
> The machine power is of 200V, an indoor wiring work may be required.
> The machine power is of 200V, an indoor wiring work may be required.
For Europe only
