5 Avoid installation to a poorly ventilated place.
6 Avoid installation to a place where there are flammable materials
or ammonia gas, etc. If the machine is installed near a diazo
copier, the picture quality may be degraded and malfunctions may
occur.
7 Install near a power outlet.
(2) Space around the machine
Install the machine with its rear side about 10cm apart from the wall in
order to allow space to ventilation by the cooling fan.
Also allow enough space around the machine for proper operation.
(3) Installation base
Set the machine in horizontal position in the following procedure.
Be sure to use a leveling instrument (UKOGM0054CSZZ) to install
the machine on a flat, horizontal place.
(Note) If the machine is not in horizontal position, the toner density
control function may not work normally, resulting in degraded
picture quality.
(4) Power source
1 Use the power source of the rated capacity.
2 Avoid complicated wiring. If not, the breaker or the fuse may be
overloaded.
(5) Grounding wire connection
1 Connect the grounding wire to prevent against a danger.
2 When connecting the grounding wire, connect only to the ground-
ing object (the grounding terminal of the power outlet, etc.) and
never connect to a gas pipe.
