You did not mention the specific code. But if it is a fuser warm up failure code such as C3421 or similar you must use the proper reset procedure for the code.
Here is the procedure. If it does not work for you then reply with the code/indication you have and I will address it.
1. Turn OFF the main power switch.
2. Turn main power switch on WHILE pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and the it has been reset.
5. After turning off the main power switch, turn it on again more than 10 seconds after and check if the machine starts correctly.
