[C4B1] Fuser unit destination selection abnormality
(1)
Check if the fuser unit is installed correctly or if its destination is correct.
(2)
Check if any harness in the fuser unit is caught.
(3)
Check if the destination of the SRAM is correct.
(4)
Replace the LGC board if any harness of the LGC board is open or short circuited.
* The first occurrence of the error C4B1 is not the determination of the error.
