Fusing Heat-shutout
To prevent the heat of the fusing unit from affecting the laser unit, this machine has fusing heat pipes. Five heat pipes [G] are integrated in the aluminum panel. The heat pipes reach the heat sink [B] in the upper left part of the machine.
The heat pipe panel intake fan [A] cools down the heat sink [B] whose temperature rises because of the circulation in the heat pipes. The heat pipe panel exhaust fan [C] sucks the hot air out of the rear of the machine.
IH Coil Cooling
The IH coil cooling fan [F] in the front side of the machine sucks in air to cool the IH coil unit [E]. This air goes through the IH coil unit [E]. Then the paper transfer belt fusing exhaust fan [D] sucks air out of the rear of the machine.
The paper transfer belt fusing exhaust fan [D] also sucks out the heat around the paper transfer belt unit.
