You have a problem with ITB.
SC 446 is ITB lift motor error (the state of the ITB lift sensor does not change its state -switching from off to on or vice versa-, even after the ITB lift motor starts rotating.


-ITB lift sensor dirty, disconnected,defective
-ITB lift motor disconnected,defective
-ITB sensor defective
-ITB lift motor defective




check back side of transfer unit , sensor and rotating actuator is there

Thanks, Miro
It worked.
I cleaned all delveoper (C,Y,M,Y) And ITB Belt sensor.
And ITB contact sensor that was attached from rear and itself.
It was leaked all toner to the sensor area.
Thanks for your big help...
