SYMPTOM
Tandem Tray does not lift up.
CAUSE
The feeler of the right tandem tray end fence is retracted and prevents the system from
detecting proper setting of the tray. This happens because the pin attached to the shaft
that rotates to lift up the bottom plate of the tray is not completely engaged with the
coupling.
