Sharp AR-M550 error code E7-02

[lky1978]

try to open the lsu unit, clean all mirrors, glasses. Maybe mirrors/glasses dusty and block the laser beam when the beam point to the laser synchronize detector.

This is not a constant problem. The machine works fine but sometime it gives that code and stops working and next day it will turn on fine. Is there any code that needs such as 61-1 or 61-2 needs to be run to get rid of this problem. thanks
