This error code is related to a Insufficient oil.
The fusing oil tank is in the rear of the machine.
You have to call Ricoh to supply the oil.

Fusing overheat error

Symptom:
Detected fusing temperature
remained above 230°C for 1
second.

Possible Cause:
• Fusing thermistor defective
• PSU defective

Hello,

The machine has no fuser oil.
Fill the little tank at the back side of the machine. If the tank is full, check the tubes, oil pump, and oil sensor.
Reboot the machine to clear the SC.
The problem will be solved

that appears to be a finisher communication problem. Check the connectors..

Enter SP mode - Clear button (yellow key), 1 0 7 and hold and press stop button (orange key).
Enter SP5-810 (SC code reset) and select “1”.
Then hold down the “Photo mode” key and the enter key(hash) at the same time for at least 3 seconds (it is not necessary to turn the main switch off andon). If the machine beeps 5 times, the reset was successful. If it only beeps twice, the reset failed, and you need to repair the machine.
Possible causes are the fusing thermistor in the fuser unit, or the power supply unit defective.
Good luck and please rate me, thanks.
