Stripper Retraction
The pawls of the fusing belt strippers [A] and pressure roller strippers [B] touch the
surfaces of the fusing belt and pressure roller during normal operation.
These strippers are held in place with small springs. If paper does not separate
from the fusing belt at [C], for example, the point of the stripper separates the
paper from the fusing belt.
The strippers retract immediately under the slightest pressure [D] if an accordion
jam occurs. This prevents the points of the strippers from damaging the surfaces of
the fusing belt or the pressure roller if a jam occurs where the paper emerges from
the nip of the hot roller and pressure roller.
The accordion jam sensor [E] checks for jams around the fusing unit strippers
when:
• The machine is turned on
• The front door is opened and closed
