Fusing Belt

This machine uses a fusing belt [A]. The paper goes between the fusing belt and
the pressure roller [F].

Heating Roller Lamp and Pressure Roller Lamp

The heating roller lamp (770W) [C] and pressure roller lamp (350W) [G] give more
heat to the front and rear edge of the fusing belt and pressure roller. The lamps
give more heat to the front edge than the rear edge. This makes fusing better for
large paper (larger than B4). If the lamp is installed in the orientation, unsatisfactory
fusing and/or paper creasing can occur.
