SOURCE: Ricoh MP C2500 Error Code SC 561 what is this?

sc561 on an MP C2500 is a thermopile error. The thermopile may need to be replaced, but first make sure it is connected properly and hasn't been moved or loosened.

You'll need to go into service mode and execute SP 5810 in order to clear the sc561 code.
