IR-3245: Need Help Resolving E0804 0000

[InlineMuse2124]

Hi All,
I am facing an issue where the machine (Canon IR-3245)is displaying E0804, intermittent between copies. I have tried replacing Power Supply board and Fans. But it didn't work. I am yet to check with the Main Control Board as it is quite expensive and risky. Is there anything else to check? Can anyone help me resolve this?
Thanks in Advance..

If you know how to repair circuits and your motherboard is broken, you can replace it. There is a resistor in the fan power supply location. The reason is that it has burned out. If not, you can only replace the motherboard with a new one.
