2. Symptom:
Minimal crack is generated at the base of the lead terminal of the capacitor (C1) due to
the external stress (production line) given to LED driver PWB and it causes the short
circuit in the capacitor, which may result in “E7-11” trouble.
3. Description: The size of capacitor (C1) of LED driver PWB has been changed from 3.2 x 2.5mm to
3.2 x 1.6mm to reduce the external stress.
- Identification of old/new LED driver PWB
- Mounting position of LED driver PWB (Scanner lamp unit section)

Example of marking (in the case of MX-2614FN/3114FN)
Before change: “E3” is marked.
After change: “E7” is marked.

If the parts code of LED driver PWB is still the old code, it is the one that the new capacitor has
been mounted and this measurement has been implemented as long as the red mark and white
mark are placed.
Red mark on the connector section (C1)
