M282N/M362N/M452N/M502N
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
not display full performances, resulting in troubles. It may also
cause safety problems. Therefore, be sure to arrange the installing
(use) conditions before setting up the machine.
A. Bringing space
For installation of a large size machine, be sure to check that the
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.
Adequate space must be provide behind the machine for proper
ventilation heat and dust. If not, the machine cannot exhibit func-
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.
(1) Power capacity
Check that the following power capacity is satisfied. If not, addition-
ally provide a power source.
Current capacity
100V: 15A or more
200V: 10A or more
NOTE: Check the shape of the power plug of the machine, and
insert it into a power outlet of the acceptable shape.
(2) Power voltage
Measure the voltage during copying to check that the voltage is in
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. 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
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 shape of the power plug of the machine, and insert it into
a power outlet of the acceptable shape.
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 horizontally installed, the toner density control is not
performed normally, degrading the copy quality.
If not, color shift or image distortion may occur.
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 humidity to
cause a paper jam or dirty copy.
Do not install the machine near a heater, a cooler, or a humidifier.
Dew may be formed inside the machine to cause a trouble. Use
enough care for ventilation.
