5-116  Exit Sensor OffThe document does not deactuate the DADF Exit Sensor after the DADF Exit Sensor actuated.ProcedureCheck the following in dC330:
ï  [5-115] DADF Exit Sensor 
ï  [5-081] DADF Exit Motor (Check Fuse F2 on DADF PWB)
The components are good.
YN
Go to the appropriate circuit and check the component
Check the following:
ï The Exit Roll for contamination, wear and a rotation failure
ï The Exit Upper/lower Chute for deformation
ï The Eliminator for deformation
ï The Exit Roll Drive Belt for disengagement and damage
ï The DADF Control PWB for failure (PL 20.3).
