Panel Housing Upper Assy (WF-7520/7510 series)
When attaching the LCD Unit to the Panel Housing Upper Assy,
the LCD Unit is secured with the ribs of the Panel Housing Upper
Assy which are ground by the positioning holes on the Shield Plate
of the LCD Unit. Therefore, the ribs become smaller than the
positioning holes when removing the LCD Unit and can not hold
the LCD Unit securely. Once the LCD Unit is removed from the
Panel Housing Upper Assy, be sure to replace the Panel Housing
Upper Assy with a new one.
