PRESSURE CONTROL MECHANISM
The graph shows how the nip width changes across the width of the fusing unit.
The dotted line going across the centre shows the ideal nip width.
The vertical dotted line marks the mid-point of the fusing unit, across the paper
path.
No fusing pressure applied
See the black line. This is the same for previous models and for this model.
