SC code 541, 542, 543, 544, 545, 546, or 547 is indicated (these SC codes cannot be canceled by the
customer).
CAUSE 1:
If the customer pulls out the fusing unit roughly, the bracket [A] is gradually tilted and the fusing connector
gradually comes out of its socket. Finally, the poor connection causes a fusing control malfunction. The
SC code displayed depends on which terminal pins are not connected correctly.
