• Code: E805-0003
• Description: The clock signal is absent for 5 sec or more after the fan drive signal has been generated. The detail codes of the fans in question are as follows:
  curl reducing fan (FM4)
• Causes: The fan wiring is faulty (short circuit, open circuit). The fan is faulty. The DC controller PCB is faulty.
• Remedy: 1. Foreign matter Is there foreign matter that prevents the rotation of the fan? YES: Remove the foreign matter. 2. Wiring, Connector Are the wiring and connector of the fan normal? Developing fan (FM1): DC controller PCB (J302B) Fixing fan (FM2): DC controller PCB (J308B) Curl reducing fan (FM4): DC controller PCB (J311B) Curl reducing fan (FM5): DC controller PCB (J311B) Electrical unit fan (FM3): main controller PCB (J1028) NO: Correct the wiring and the connection. 3. Fan, DC controller PCB Try replacing the fan. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.

• Code: E805-0005
• Description: The clock signal is absent for 5 sec or more after the fan drive signal has been generated. The detail codes of the fans in question are as follows:
  electrical unit fan (FM3)
• Causes: The fan wiring is faulty (short circuit, open circuit). The fan is faulty. The DC controller PCB is faulty.
• Remedy: 1. Foreign matter Is there foreign matter that prevents the rotation of the fan? YES: Remove the foreign matter. 2. Wiring, Connector Are the wiring and connector of the fan normal?

• Code: E901-0000
• Description: The motor ready signal does not arrive within 1.3 sec after the pedestal main motor drive signal is generated
• Causes: The connector has poor connector. The pedestal main motor is faulty. The main power supply PCB is faulty. The pedestal controller PCB is faulty. The DC controller PCB is faulty.
• Remedy: 1. Connector Is the wiring between the pedestal controller PCB and the main power supply PCB and between the main power supply PCB and the DC controller PCB normal? NO: Correct the wiring. 2. Main power supply PCB Is the voltage between J206-2 (+) and J206-1 (-) on the main power supply PCB about 24 V? NO: Replace the main power supply PCB. 3. Pedestal main motor Try replacing the pedestal main motor. Is the problem corrected? YES: End. 4. Pedestal controller PCB, DC controller PCB Try replacing the pedestal controller PCB. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.
