Symptom
JAM 97(Shift over) or SC516-02 (Shift motor sensor edge error) may occur.
Note: SC516-02 appears on the panel when JAM97 occurs three times.
Cause
There is a gap [A] between the edge detection unit bracket and the edge of the attached Mylar [B].
The paper edge gets stuck in this gap, triggering JAM 97.
Note: This gap [A] is normally controlled at the factory to within 0.5mm.
