1. Installing (use) conditions
Before installing the machine, check that the following installing
(use) conditions are satisfied.
If the installing (use) conditions are not satisfied, the machine may
have performance issues resulting in errors. It may also cause
safety problems. Ensure there is room to move the product in and
arrange the installing (use) conditions before setting up the
machine.

A. Transporting product
For installation of a large size machine, be sure to check that the
door size is wide enough before bringing in.
door size is wide enough before bringing in.
B. Installing space
The following space must be provided around the machine in order
to assure machine performances and proper operations.
If any option is installed, provide the additional space for installing
it.
There must be sufficient space for ventilation at the rear of the
machine to avoid malfunction from heat and dust.

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.
exhibit full performances and may cause safety trouble.
Strictly observe the following specifications.
(1) Power capacity
Check that the following power capacity is satisfied. If not satisfied,
an addition power source will need to be supplied.
Current capacity
Japan (100V): 15A
100V (100 - 127V): 12A
200V (220 - 240V): 8A

(2) Power voltage
Measure the voltage during copying to check that the voltage is in
the range of the specified voltage
the range of the specified voltage
10%.
If the voltage is outside the specified range, use thicker lead wires
to reduce impedance.
(An electrical work is required.)
Use of a step-up transformer is also available. The step up trans-
former must have a great capacity then the maximum power con-
sumption of the machine.
to reduce impedance.

former must have a great capacity then the maximum power con-
sumption 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.
2%. If power waveform is deformed, a trouble may occur.
(4) Safety
Make certain the machine is properly grounded at the outlet.
Grounding (earth connection) must be performed before inserting
the power plug into the power outlet.
When disconnecting the earth connection, be sure to disconnect
the power plug from the power outlet in advance.

(5) Power plug
Check the style of the power plug. If the shape does not match, do
not use it.
not use it.
D. Floor strength and level
This machine is considerably heavy and becomes heavier with an
option installed.
The floor must be strong enough for assuring safety.
If the unit is not level, the toner density control is not performed nor-
mally, degrading the copy quality.
Color shift or image distortion may also result.

E. Direct rays of the sun, dust, temperature,
humidity, gasses, chemicals, vibration
(1) Temperature and humidity
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 moisture to
cause a paper jam or dirty copy.
Do not install the machine near a heater, a cooler, or a humidifier.
