Have you tried to reset the sc code with sp 5-810>?

Re: Sc543 on Ricoh Mpc2050

Are you sure its even the board, have you removed the fusing uint and checked that everything is working correctly and then done the sc code reset in service mode...

It could save you alot of time and money, Just follow the service manual for this machine

And if you have not got one, paul does them cheap

This is a common error, just replace the pressure roller thermistor, and reset the code. part # = AW100129 for the 220v model. Not sure about the NA 110v one.

Hi I think there is an error with the part number above as that refers to an MPC300.

I had the same error and replaced the center thermistor (which was new at the time!) and the error went away (AW100127).
