The Ricoh error code 548 / SC548 is a fusing unit error code. If you are getting this error: Check the fuser unit to see if it is set properly. There are some connections on the fuser unit not making good contact.

Most common problem is the electrical connector on the fusing unit or the connector that the fusing unit connects to inside the machine is broken. So when you push the Fusing Unit in to the machine the connector moves out of position and doesn't connect properly.

some potentially useful information can be found here: what the error codes mean, and the services manual; (I have pointed to error code 792 but the others are different pages), there is a copy of the service manual too. This is only a starting point !

Check the Ricoh site. Select your country then look for your model # and search for the error code or knowledge base etc.

Is the supply voltage ok?
The problem is to do with the IH inverter (it is part of the fusing unit).
Any cables loose?

It would help to know the code. Like SCxxx.
