C. Fusing cooling path
The air inside the machine is sucked in by the fusing cooling fans /Fr (FM2) [6] and /Rr (FM8) [1] to be blown
against the edges of the fusing roller [3] through the ducts [2] and [5]. In this way, the edges of the fusing roller
are cooled down and the surface temperature of the edges of the fusing pressure roller [4] that is in contact also
goes down.

Envelope conveyance mechanism

When printing envelopes, to prevent the occurrence of paper crease due to the thickness of paper, it is possible
to switch the nip pressure of the fusing roller and the fusing pressure roller. The nip pressure is manually
switched by the envelope lever [1].
