How to reset Ricoh Error Code sc542 sc546 sc548 problem ...Ricoh Aficio copiers : AFICIO 1013 F
That service code SC550 normaly is a fuser web end error, you must replace the web and reset the % in 1.902 to "0". But i dont think the Ricoh aficio 450 have a fuser web. does this SC550 coming from your Aficio 450?
I cant seem to find SC550 in the Aficio 450 service manual but it usually refers to the cleaning web.
You can reset the cleaning web counter in service mode but i would advise that you check the web first.
The web is located above the fusing unit and is a white colour oil impregnated material, it is in contact with the hot roller and usually lasts around 100k clicks.
Are you 100% sure you have the correct model number ?
Fusing lamp overheat error (rear) 555 A After the fusing temperature reaches the target temperature, the fusing lamp does not turn off for 20 consecutive seconds. ?? Fusing thermistor defective or out of position ?? Power supply board defective
