Hi I have problem with my photocopaier. Sharp ARM236. It shows Code: U2-40


U2-04 EPROM error
U2-11 Main counter error
U2-12 EPROM error

As you can see there are many U2 error codes. Needless to say, find your code and the replace the bad part. The battery is on the main board. The EPROM is on the main board.
If you find your code, replace the part and error still remains -- replace main board.
