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.
