Hello sir; The U-4 code all are fuser problem, there haave noway to fix it the only way is replace the fuser unit

Hello sir; The U-9 code means the main control unit/switch board problem, replace it.

A U4 is a fuser overtemperature.
You can hold down the "0" while powering the machine on. That will enter the machine into diagnnostics.
Next enter code 401, and press start, See of that clears the problem.
If it does. Remove the fiser and clean the buildup off the thermistor.
If it doesnt you will most likely have to replace the fuser.
