Avoid exposing the copier to rapid changes in temperature.
If the room in which the copier is installed is cold but rapidly heated, water droplets
(condensation) may form inside the copier. 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 copier near televisions, radios, or similar electronic equipment.
The copier might interfere with sound and picture signal reception. Plug the copier into a
