• Code: E000
• Description: Fixing unit startup defect
• Causes: The detected temperature of the main thermistor does not rise above 5 deg C (temperature at power ON is 0 deg C) within one second of the heater being energised. Cause: Main thermistor broken wire, fixer heater broken wire, DC controller PCB defect
• Remedy: - Check the connector of the low-voltage power supply PCB. - Replace the fixing film unit. - Replace the DC controller PCB.

• Code: E001-0000
• Description: Abnormally high temperature in fixing unit
• Causes: The detected temperature of the main thermistor is 225 deg C (equivalent to approx. 0.84V) or higher for 0.5 sec. or longer. Cause: Main thermistor defect, DC controller PCB defect
• Remedy: - Check the connector of the low-voltage power supply PCB. - Replace the fixing film unit. - Replace the DC controller PCB.

• Code: E001-0001
• Description: Abnormally high temperature in fixing unit
• Causes: The detected temperature of the main thermistor is 245 deg C (equivalent to approx. 2.12V) or higher for 0.5 sec. or longer. Cause: Main thermistor defect, DC controller PCB defect
• Remedy: - Check the connector of the low-voltage power supply PCB. - Replace the fixing film unit. - Replace the DC controller PCB.

• Code: E003-0000
• Description: Abnormally low temperature in fixing unit
• Causes: The detected temperature of the main thermistor is 100 deg C (equivalent to approx. 2.60V) or lower for 0.5 sec. or longer. Cause: Low voltage power supply circuit board defect, main thermistor broken wire, DC controller PCB defect
• Remedy: - Check the connector of the low-voltage power supply PCB. - Replace the fixing film unit. - Replace the DC controller PCB.

• Code: E003-0001
• Description: Abnormally low temperature in fixing unit
• Causes: The detected temperature of the sub-thermistor fails to reach 100 °C (equivalent to approx. 0.38V) within 0.5 sec. or longer of the heater being energised. Cause:Sub-thermistor defect, DC controller circuit board defect
• Remedy: - Check the connector of the low-voltage power supply PCB. - Replace the fixing film unit. - Replace the DC controller PCB.

• Code: E004
• Description: Abnormality in fixing unit power supply drive circuitry
• Causes: Zero cross signal could not be detected within specified time limit. Cause: Fixing control circuitry defect
• Remedy: - Replace the low-voltage power supply PCB.

• Code: E012-0000
• Description: Motor startup abnormality
• Causes: ETB motor speed detection signal frequency does not reach specified frequency within 3.5 sec. or longer of the ETB motor drive starting. Cause: ETB motor defect, DC controller PCB defect
• Remedy: - Replace ETB motor - Replace DC controller PCB

• Code: E012-0001
• Description: Motor startup abnormality
• Causes: ETB motor speed detection signal frequency reaches the specified frequency but is then out of synch after 2 sec. or longer of operation. Cause: ETB motor defect, DC controller PCB defect
• Remedy: - Replace ETB motor - Replace DC controller PCB
