This copier is equipped with heaters to avoid condensation inside. These heaters are kept
powered as long as the copier power cable is connected to a wall outlet with the main switch
set off. Never disconnect the power cable if the copier is used in a humid place of 70%RH

If the copier is not going to be used for long periods of time, disconnect the power cable from
the wall outlet.
Each roll unit of this copier is equipped with a roll unit heater
turned on or off with a switch. If normal plain paper is kept in the roll units and there is a risk
of high humidity, keep their heaters on. However, keep the heater off if tracing paper is kept
in the roll unit.

not going to be used for a long time, take paper out of the roll unit, put it in the original
