MX-B201/B201D  UNPACKING AND INSTALLATION  5 - 1

：'11/Oct/17

Improper installation may damage the copier. Please note the fol-
lowing during initial installation and whenever the copier is moved.

Caution: If the copier is moved from a cool place to a warm place,

condensation may form inside the copier. Operation in
this condition will cause poor copy quality and malfunc-
tions.
Leave the copier at room temperature for at least 2 hours
before use.

Do not install your copier in areas that are:

• damp, humid, or very dusty

• exposed to direct sunlight

• poorly ventilated

• subject to extreme temperature or humidity changes, e.g., near

an air conditioner or heater.

The copier should be installed near an accessible power outlet for
easy connection.

Be sure to connect the power cord only to a power outlet that
meets the specified voltage and current requirements.

Also make certain the outlet is properly grounded.

Be sure to allow the required space around the machine for servic-
ing and proper ventilation.

Be careful in handling the copier as follows to maintain the perfor-
mance of this copier.

Do not drop the copier, subject it to shock or strike it against any
object.

Do not expose the drum cartridge to direct sunlight.

Doing so will damage the surface (green portion) of the drum car-
tridge, causing poor print quality.

Store spare supplies such as drum cartridges and toner cartridges
in a dark place without removing from the package before use.

If they are exposed to direct sunlight, poor print quality may result.

Do not touch the surface (green portion) of the drum cartridge.

Doing so will damage the surface of the cartridge, causing poor
print quality.

Open the carton and check if the following components and acces-
sories are included.
