Note:
1. At the end of a printing run, the heat discharge fan 3 (FM3) stops once. However,
the heat discharge fan 2 (FM2) will stop 30 min after the printer unit power switch
is turned off to prevent increase in temperature inside the printer unit.
2. The heat discharge fan 1 (FM1) is equipped with a built-in thermistor used as part
of the mechanism to vary the rotation speed of the fans to suit the machine inter-
nal temperature.
