It could also be a fault in the wiring, power to or signal from. It could be insufficiant power being supplied to the fuser or the microchip that receives the signal from the fuser thermistor is bad. It sounds like a possible circuit board problem. If it was intermittent and you're getting it with another fuser too it's probably not the fuser. If you're going to try this at least wait 20 minutes for the fuser to cool down first.ĭave Kennett 3 years Middleton That's generated because the thermistor is not seeing the required temperature after a certain amount of time. There is a reason why fuser SC codes require a trained service technician to reset them in service mode. All other SC codes can be reset simply by turning the machine off and on again. You now have 2 problems which need to be fixed. By the time the thermistor is checked your fuser would be at 300C degrees except Ricoh has built in a backup. Your fuser was already heated to 150C degrees. It will stay powered on until the sensor is checked again at that set amount of time but now we aren't starting at room temperature. Now you go and reset it and the fuser powers back up. Your fuser might already be at that temperature, lets say 150C degrees, but the sensor didn't see it and the machine powered off with the SC code. It could be because that sensor is faulty. One of the main reasons one of these codes is generated is because there is a sensor which monitors the fuser's temperature and it did not see the fuser rise to a specific temperature after a set amount of time. As a retired Ricoh Technical Trainer I would like to warn the general public from doing this.
