DESCRIPTION:
##359 (for MFP) / 13 Alternating Blinks (for SFP) Paper Feed Position Error
SOLUTION(S):
Realign the Lift Cam Shaft Assembly
Sudden movement or impact (i.e. from shipping) may cause the Lift Cam Shaft Assembly to shift. When this
occurs, the Cam Shaft slides inside the bracket to the right, which prevents the Cam Shaft from rotating
properly. This will cause a ##359 (for MFP) / 13 Alternating Blinks (for SFP) Paper Feed Position Error.
