Fusing
Fuser Unit
The fusing belt has a thick elastic layer, as with the previous model, to allow the belt to reach farther into
the surface indentations of textured media.

There are 5 heaters in the heating roller [2].
Toner is fused onto the media by applying heat to the fusing belt [1] via the heating roller [2],
maintaining consistent temperature and pressure on the media.
The fusing temperature is dependent upon the amount of toner.
The more there is toner, the more heat needed for fusing.
The fusing temperature can be adjusted separately for both print modes; FC and BW.
The fusing temperature is momentarily increased one notch immediately before the paper passes
through the nip, to compensate for the slight temperature drop of the fusing belt [1] due to the heat
absorption by the paper.
