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

U4 code refers to a fuser heat failure, you'll probable find the fuser roll is stone cold .Possible cause is open circuit heater or overheat thermostat popped.Either way you will need to pull out the fuser unit and check continuity of the components
