5. Never touch the plugs on either end of the power cable with wet hands. This can cause an
electric shock. When servicing the machine, remove the power plug from the wall socket.
6. Use caution when inserting or removing the power connector. The power connector must be
inserted completely otherwise a poor contact could cause overheating and possibly lead to a
fire. When removing the power connector grip it firmly and pull.
7. Take care of the power cable. Do not allow it to become twisted, bent sharply round corners
or otherwise damaged. Do not place objects on top of the power cable. If the power cable is
damaged, it could overheat and cause a fire or exposed cables could cause an electric
shock. Replace a damaged power cable immediately, do not reuse or repair the damaged
cable. Some chemicals can corrode the coating on the power cable, weaken the cover or
exposing cables causing fire and shock risks.
8. Ensure that the power sockets and plugs are not cracked or broken in any way. Any such
defects should be repaired immediately. Take care not to cut or damage the power cable or
plugs when moving the machine.
9. Use caution during thunder or lightning storms. Xerox recommend that this machine be dis-
connected from the power source when such weather conditions are expected. Do not touch
the machine or the power cord if it is still connected to the wall socket in these weather condi-
tions.
10. Avoid damp or dusty areas, install the machine in a clean well ventilated location. Do not
position the machine near a humidifier. Damp and dust build up inside the machine can lead
to overheating and cause a fire.
11. Do not position the machine in direct sunlight. This will cause the temperature inside the
machine to rise possibly leading to the machine failing to work properly and in extreme condi-
tions could lead to a fire.
12. Disconnect the machine from the power supply immediately if it emits any strange odour,
smoke or strange noises. If this precaution is ignored, the machine could overheat and a fire
may occur.
13. Do not insert any metal objects into the machine through the ventilator fan or other part of the
casing, it could make contact with a high voltage conductor inside the machine and cause an
electric shock.
