Avoid exposing the machine to rapid changes in temperature.
If the room in which the machine is installed is cold but rapidly heated, water droplets (condensation)
may form inside the machine. This may result in a noticeable degradation in the quality of the copied
image, the inability to properly scan an original, or the copies having no printed image at all.
Avoid installing the machine near computers or other precision electronic
equipment.
Electrical interference and vibrations generated by the machine during printing can adversely affect the
operation of such equipment.
