6.15.4 FUSING UNIT VENTILATION
[A]: Fusing unit
[B]: Heat sink
[C]: Fusing cooling fan

Heat rising from the fusing unit [A] collects around a heat sink [B]. The heat sink
contains pipes with water that help to cool the hot air.
The fusing cooling fan [C] pulls cool air into the machine and blows it over the heat
sink. The fusing exhaust fan [D] pulls the heated air away from the heat sink and
expels it through a vent.
