Safety Precautions
To use the machine safely
Please keep these instructions for later reference and read them before attempting any maintenance.
• If there are faxes in the machine's memory, you need to print them or save them before you turn off
the power and unplug the machine.
WARNING
There are high voltage electrodes inside the
machine. Before you clean the inside of the
machine, make sure you have unplugged the
telephone line cord first and then the power cord
from the AC power outlet.
Do not handle the plug with wet hands. Doing this
might cause an electrical shock.
After you use the machine, some internal parts are
extremely HOT! To prevent injures, be careful not
to put your fingers in the area shown in the
illustration.
The fixing unit is marked with a caution label.
Please do not remove or damage the label.
• Use caution when installing or modifying telephone lines. Never touch telephone wires or terminals
that are not insulated unless the telephone line has been disconnected at the walljack.
1

Never install telephone wiring during a lightning storm. Never install a telephone wall jack in a wet location.
• This product must be installed near an AC power outlet that is easily accessible. In case of an
emergency, you must disconnect the power cord from the AC power outlet to shut off the power
completely.
Do not use a vacuum cleaner to clean up scattered toner. Doing this might cause the toner dust to ignite
inside the vacuum cleaner, potentially starting a fire. Please carefully clean the toner dust with a dry, lint-
free cloth and dispose of it according to local regulations.
WARNING
DO not use any type of spray to clean inside or outside of the machine. Doing this may cause a fire or
electrical shock.
WARNING
