The error means - Fusing unit rotation error.
Check if the fusing unit(right door{hot unit}) ,if it is rotating properly.
There could also be a sensor on the frame or the machine which senses the fusing unit rotation,(the sensor sometimes comes off)(remove the fusing unit and check where the fusing unit is seated).
Also try cleaning the sensor with a blower or brush.

that is a fuser overheat code. You can try pressing clear all, then enter 107 and hold the stop button until you see the SP mode come on the machine, then as it is in that mode, shut the machine off and back on.
If that doesnt work. I would suggest replacing the fuser unit.
You would need thermistors, rolls, overheat thermostadts.
Individually they would cost more than replacing the fuser.
