I cleaned the thermistors in the fuser which were dirty. I tried using the instruction for Ricoh, but using either clear or reset, then 107 and holding stop did not work to get me into the next screen. SOLVED: Use Reset - 107 - Clear. NOW YOU ARE ON YOUR OWN. I believe following the rest of Ricoh instructions might work, but we had a service tech lead us through.

Press the “Up/Down arrow” keys together for about 5 seconds, and then press the

The machine automatically goes off line when you enter the service mode.
enter SP 5810 and reset the SC 543 **** if again appears please do not reset it again because you may do bigger problem and damage more part than ware damaged in first place .
The SC code says that the termistor is damaged so check on the fusing unit dose the termistor is standing in good position or has dirt on the surface of he termistor.
