There isn't much to it: The system board fan, the system board & (2) connectors (CN112 & a union). That's it.
Are you getting 24vdc at the fan connector?
AFAIK there is not a 03 mode to test that fan motor. It runs constantly whenever the machine is on.
Are you sure that it's the system board fan M6 that you changed?: It's here:

If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Hi
I checked voltage and cn112 connector comes 9.3vdc
Fan voltage not 24vdc it shows 12vdc
If anyone have circuit diagram manual i can check why 12vdc not create on connector cn112
Thanks...
It's unlikely to be a power supply. I'd say your best chances are with the system board.
There's an odd chance that you've got a dead short or pinched wire in another component that's running off the same power supply lead. The next thing to do is determine which other components share the same connection to the power supply and disconnect those, to see if your supply voltage comes back up. =^..^=

Hi
I think this is not power problem, bcaz we gave 12v separately to the fan power and checked , still same error.
I think fan signals not sent to correct path , to control ic.
If anyone have circuite diagram of 256se it will help a lot to find the problem...
Thx.
