I turn on the machine and start printing, but it says wait for a while and stops doing any other work. Then the error code E00315 is displayed immediately.
So what I can do is put all the circuit cards in the back of the device into another device of the same type and try it and everything is fine.
It's still good for about a day after returning to the original. The next day it shows the same error code as usual.
No circuit board has been appointed yet.
Please help me.
