INSTALLATION
1. Installing (use) conditions
Before installing the machine, check that the following installing (use)
conditions are satisfied.
conditions are satisfied.
If the installing (use) conditions are not satisfied, the machine may not
display full performances, resulting in troubles. It may also cause
safety problems. Therefore, be sure to arrange the installing (use) con-
ditions before setting up the machine.
display full performances, resulting in troubles. It may also cause
safety problems. Therefore, be sure to arrange the installing (use) con-
ditions before setting up the machine.
A. Bringing space
For installation of a large size machine, be sure to check that the door
size is great enough before bringing in.
size is great 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.
assure machine performances and proper operations.
If any option is installed, provide the additional space for installing it.
Especially the space at the rear of the machine must be provided suffi-
ciently. If not, the machine cannot exhibit functions against heat and
dust, causing some troubles.
ciently. If not, the machine cannot exhibit functions 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.
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, additionally
provide a power source.
provide a power source.
Current capacity
Japan: 20A or more
100V: 20A or more
200V: 10A or more
(2) Power voltage
Measure the voltage during copying to check that the voltage is in the
range of the specified voltage ±10%.
range of the specified voltage ±10%.
If the voltage is outside the specified range, use thicker lead wires to
reduce impedance.
reduce impedance.
(An electrical work is required.)
Use of a step-up transformer is also available. In this case, the capac-
ity must be great enough for the max. power consumption of the
machine.

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
Be sure to properly ground the machine.
(5) Power plug
Check the form of the power plug. If the shape does not match, do 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, and the machine
must be installed horizontally.
must be installed horizontally.
If not, toner concentration control is not properly performed, resulting in
degraded copy quality and distorted images.

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 tem-
perature and humidity. If the temperature and humidity exceeds the
specified range, the machine may not operate properly and or cause
equipment failure.
