MX-2301N DEAD

There is a small board which the memory board is connected to, it has about three fuses. One of it is likely broken, if it is, then replace it. I had such an issue but it was for ARM. It may work for u too. Goodluck

Thanks a lot for your reply Alpanapa but what does it mean in Sharp language : Reus Asic trouble ??
(I have all Leds on)

ASIC: Application Specific Integrated Circuit
Check the MFP control PWB, you will find something like this: Buffalo_IFC-ILP4_VIA_VT6306.jpg This is an ASIC.

I had one customer with that problem, i found out that it was something wrong with the power on the machine (The whole MFP was leaking 130 Volt, it was a fun thing to find out )
After fixing the volt leaking problem, i also had all lights on the MFP PWB, with the Reus Asic Trouble, so i changed the hole MFP PWB card and it has been working for over 1 year now.

I decided to remove the low voltage power supply first , to verify
if it has a real problem.
It seems that it is not an easy repair procedure , because i don't have the information how to remove it from the machine!!
By the way i will check everything else has been suggested here..
I'll be back!
