You might have an open heating element.
Normal room temperature reading should be 25 to 27 degrees when checked in System SP display temperatures.
Did you reset SC code in SP mode?

Fuser does not attempt to warm up atll.
After I reset the sc code , it came up with SC547, whcih is pointing to power supply. There is no ourput power to the heaters of the fuser unit, looks like the relays are not commanded by the control unit to turn the heaters on. Do you know how the commands are generated to turn the power on to the heaters of the fuser unit?
