Description: Heating roller warm-up failure
• The thermistor /1 does not detect the specified temperature and the warm-up cycle is not completed even after the lapse of a given period of time after the cycle has been started.
Remedy: 1 Check the fuser unit for correct installation (whether it is secured in position). 2 Check the connector between fuser unit- PRCB PJ26 for proper connection and correct as necessary. 3 Check the connector between fuser unit- DCPU CN2 for proper connection and correct as necessary. 4 Change fuser unit. 5 Change PRCB. 6 Change DCPU.
Code: 0502
Description: Thermistor open-circuit failure
• The temperature detected by the thermistor/1 does not reach a predetermined level even after the lapse of a given period time after the warm-up cycle has been started.
Remedy: 1 Check the fuser unit for correct installation (whether it is secured in position). 2 Check the connector between fuser unit- PRCB PJ26 for proper connection and correct as necessary. 3 Check the connector between fuser unit- DCPU CN2 for proper connection and correct as necessary. 4 Change fuser unit. 5 Change PRCB. 6 Change DCPU.
Code: 0503
Description: Thermistor resistance failure
• The difference between the temperature detected by thermistor/1 and that detected by thermistor/2 exceeds a predetermined value.
Remedy: 1 Check the fuser unit for correct installation (whether it is secured in position). 2 Check the connector between fuser unit- PRCB PJ26 for proper connection and correct as necessary. 3 Check the connector between fuser unit- DCPU CN2 for proper connection and correct as necessary. 4 Change fuser unit. 5 Change PRCB. 6 Change DCPU.
Code: 0510
Description: Abnormally low heating roller temperature
• The temperature detected by the thermistor /1 remains lower than the specified value for a given period of time or longer.
Remedy: 1 Check the fuser unit for correct installation (whether it is secured in position). 2 Check the connector between fuser unit- PRCB PJ26 for proper connection and correct as necessary. 3 Check the connector between fuser unit- DCPU CN2 for proper connection and correct as necessary. 4 Change fuser unit. 5 Change PRCB. 6 Change DCPU.
Code: 0520
Description: Abnormally high heating roller temperature
• The temperature detected by the thermistor /1 remains higher than the specified value for a given period of time or longer.
• The heater lamp remains ON for a given period of time or longer.
Remedy: 1 Check the fuser unit for correct installation (whether it is secured in position). 2 Check the connector between fuser unit- PRCB PJ26 for proper connection and correct as necessary. 3 Check the connector between fuser unit- DCPU CN2 for proper connection and correct as necessary. 4 Change fuser unit. 5 Change PRCB. 6 Change DCPU.
Code: 0F52
Description: Toner level sensor/Y malfunction
• An error occurs on the toner level sensor for each color.
Remedy: 1 Check the connector between each sensor- PRCB PJ25 for proper connection and correct as necessary. 2 Replace the toner level sensor of the corresponding color. 3 Change PRCB.
