From things I have read about this error code, it could be happening because of using compatible sublimation inks which is causing this problem.

sc441 error means one or more of the developer unit(PCU) isnt rotating. you have to take the PCU out to see which color isnt rotating. there maybe one of the doctor blade is flipped, usually caused by lack of toner in the PCU.

It's not the PCU (photoCONDUCTOR unit), It's either a thermistor or blown out heater lamp in the fuser. Call a tech. The code can only be reset in service mode
