The machine has four fans [A] [B] [E] [F] to ventilate the interior of the machine. There is a
temperature/humidity sensor [D] at the front (lower right) of the machine. The machine takes in air from the left
of the machine and exhausts it from the right of the machine after it cools the machine interior.
The ozone filter [C] is installed at the right of the fusing fan, which helps make it easier to replace the filter.
