Machine Environment
Choose your machines location carefully.
Environmental conditions greatly affect its performance.
Optimum Environmental Conditions
The following describes precautions when locating the machine.
R CAUTION:
R CAUTION:
R CAUTION:
 Temperature: 10-32 °C (50-89.6 °F) (humidity to be 54% at 32 °C, 89.6 °F)
 Humidity: 15-80% (temperature to be 27 °C, 80.6 °F at 80%)
 Ventilation: 3 times/hr/person or more
 A strong and level base.
 The machine must be level within 5 mm, 0.2 inches: both front to rear and left
to right. Keep the machine away from humidity and dust. Otherwise a fire or an elec-
tric shock might occur.
Do not place the machine on an unstable or tilted surface. If it topples over, 
an injury might occur.
After you move the machine, use the caster fixture to fix it in place. Other-
wise the machine might move or come down to cause an injury.
Make sure the room where you are using the machine is well ventilated and 
spacious. Good ventilation is especially important when the machine is used 
heavily.

Environments to Avoid
 Locations exposed to direct sunlight or other sources of strong light (more
than 1,500 lux).
 Locations directly exposed to cool air from an air conditioner or heated air from a heat-
er. (Sudden temperature changes can cause condensation to form inside the machine.)
 Locations close to machines generating ammonia, such as a diazo copy machine.
 Places where the machine will be subject to frequent strong vibration.
Dusty areas.
 Areas with corrosive gases.
Moving
The following describes precautions when moving the machine.

R CAUTION:
Important
❒Be careful when moving the machine. Take the following precautions:
 Turn off the main power. See p.35 “Turning Off the Main Power / In the
Event of Power Failure”.
 Unplug the power cord from the wall outlet. When you pull out the plug
from the socket, grip the plug to avoid damaging the cord, thereby reduc-
ing the risk of fire or electric shock.
 Close all covers and trays, including the front cover and bypass tray.
❒Do not take off the holding stand.
❒Protect the machine from strong shocks. Impact can damage the memory. Before moving the machine, be sure to pull all four handles fully out. If not, 
an injury might occur. After moving the machine, return the four handles to 
their original positions.
 Before moving the machine, be sure to disconnect all external connections, 
especially the power cord from the wall outlet. Damaged power cords are a 
fire and electric shock hazard.
If you have to move the machine when the optional paper tray unit is at-
tached, do not push on the main units top section. Doing so can cause the 
optional paper tray unit to detach, possibly resulting in injury.
Unplug the power cord from the wall outlet before you move the machine. 
While moving the machine, you should take care that the power cord will not 
be damaged under the machine.

R CAUTION:
R CAUTION:
R CAUTION:
 Make sure the plug is inserted firmly in the wall outlet.
 Voltage must not fluctuate by more than 10%.
 The wall outlet shall be installed near the machine and shall be easily accessible. Connect the machine only to the power source described on the inside 
front cover of this manual. Connect the power cord directly into a wall 
outlet and do not use an extension cord.
Do not damage, break or make any modifications to the power cord. 
Do not place heavy objects on it. Do not pull it hard nor bend it more 
than necessary. These actions could cause an electric shock or fire.
Unplug the power cord from the wall outlet before you move the machine. 
While moving the machine, you should take care that the power cord will not 
be damaged under the machine.
If the power cord is damaged (exposure of the core, disconnection, etc.), 
contact your service representative to change a new one. Operating the ma-
chine with a damaged power cord may cause an electric shock or fire.
When you disconnect the power plug from the wall outlet, always pull the 
plug (not the cable).
To disconnect the power cord, pull it out by plug. Do not drag the cord itself. 
Doing so may result in damage to the cord, leading to fire or electric shock.
