Turn off the power switch, and remove the fixing assembly. Measure the resistance between connectors J50B-2 (FSRTH) and J50B- 3 (GNDTH) on the fixing assembly side. Is it between 120k and 290k Ohm NO: Check the wiring from J222 on the DC controller PCB to the thermistor; if normal, replace the thermistor. Main heater 2) With the fixing assembly removed, is there electrical continuity between connectors J50-3 (FSRN1) and J50-5 (FSRL1) on the fixing assembly side? NO: Replace the main heater. Sub heater 3) With the fixing assembly removed, is there electrical continuity between connectors J50-4 (FSRN2) and J50-5 (FSRL2) on the fixing assembly side? NO: Replace the sub heater. Thermal switch, DC controller PCB 4) Remove the fixing assembly, and detach the wiring cover. Is there electrical continuity between the terminals of the thermal switch? NO: Replace the thermal switch. YES: Replace the DC controller PCB

• Code: E009
• Description: The type of fixing assembly is wrong
  • The rated voltage of the machine and the rated voltage of the fixing assembly do not match.
• Remedy: Fixing assembly 1) Is the fixing assembly rated at a voltage different from that of the power supply? YES: Replace the fixing assembly so that its voltage matches the fixing assembly. Power supply assembly, DC controller PCB 2) Replace the power supply assembly. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.

• Code: E010
• Description: The main motor fails to start up normally
  • The revolution of the main motor fails to reach a specific revolution.
• Remedy: Connector 1) Is connector J12 of the main motor and connector J218 on the DC controller PCB connected correctly? YES: Connect them correctly. Switch, Door switch of sensor PCB 2) Disconnect connectors J205 and J221 from the DC controller PCB. Is there electrical continuity between J205-3 (+24 V) and J221-1 (+24 VB) on the harness side when the door switch (SW1401) is turned on? NO: Replace the switch/sensor PCB. Main motor, DC controller PCB 3) Can the main motor be rotated using a printer driver checker? NO: Replace the main motor.

• Code: E011
• Description: The main motor fails to rotate normally
  • The revolution of the main motor deviates from a specific revolution.
• Remedy: Connector 1) Is connector J12 of the main motor and connector J218 on the DC controller PCB connected correctly? YES: Connect them correctly. Switch, Door switch of sensor PCB 2) Disconnect connectors J205 and J221 from the DC controller PCB. Is there electrical continuity between J205-3 (+24 V) and J221-1 (+24 VB) on the harness side when the door switch (SW1401) is turned on? NO: Replace the switch/sensor PCB.
