FM 120 was not rotating.
Error code
E805 0402.
|
Error: pre-fixing feed rear right fan (FM120) |
CANON
After swapping fan FM120 with FM121, neither fan would rotate.
Conclusion: FM 120 was bad and blew out the driver pcb (UN106).
Recommend to check the wiring from the driver pcb (UN106) to the fan FM120. Replace the fan and driver pcb (UN106) as a set.
Note 1: Fans FM120 and FM121 are the same.
Note 2: The service manual calls
UN106 the Secondary transfer/duplexing driver PCB. The parts manual calls this board V. Path Feed Driver Assy LW.
