Description: Abnormal image transfer voltage (HV)
- The image transfer voltage remains more than 100 V continuously for a given period of time while the drum remains stationary.
Remedy: 1 Check the transfer roller unit for installation. 2 Change HV1. 3 Change MFPB.
Code: C3451
Description: Warming-up failure
- The thermistor/1 (TH1) detected that the temperature of the surface of the fusing roller did not reach the specified level even after the lapse of given period of time has passed during warm-up.
Remedy: 1 Check the fusing unit for correct installation. 2 Check the open/close operation of the right door. 3 Check the fusing unit, DCPU and MFPB for proper connection and correct or change as necessary. 4 Change fusing unit. 5 Change MFPB. 6 Change DCPU.
Code: C3452
Description: Warming-up failure (sub)
- The thermistor/2 (TH2) detected that the temperature of the surface of the fusing roller did not reach the specified level even after the lapse of given period of time has passed during warm-up.
Remedy: 1 Check the fusing unit for correct installation. 2 Check the open/close operation of the right door. 3 Check the fusing unit, DCPU and MFPB for proper connection and correct or change as necessary. 4 Change fusing unit. 5 Change MFPB. 6 Change DCPU.
Code: C3751
Description: Abnormally high fusing temperature (main)
- The temperature detected by the thermistor/1 (TH1) is over the specified temperature for more than the specified period of time after power is turned ON.
Remedy: 1 Check the fusing unit for correct installation. 2 Check the open/close operation of the right door. 3 Check the fusing unit, DCPU and MFPB for proper connection and correct or change as necessary. 4 Change fusing unit. 5 Change MFPB. 6 Change DCPU.
Code: C3752
Description: Abnormally high fusing temperature (sub)
- The temperature detected by the thermistor/2 (TH2) is over the specified temperature for more than the specified period of time after power is turned ON.
Remedy: 1 Check the fusing unit for correct installation. 2 Check the open/close operation of the right door. 3 Check the fusing unit, DCPU and MFPB for proper connection and correct or change as necessary. 4 Change fusing unit. 5 Change MFPB. 6 Change DCPU.
Code: C3851
Description: Abnormally low fusing temperature (main)
- The temperature detected by the thermistor/1 (TH1) is below the specified temperature for more than the specified period of time.
Remedy: 1 Check the fusing unit for correct installation. 2 Check the open/close operation of the right door. 3 Check the fusing unit, DCPU and MFPB for proper connection and correct or change as necessary. 4 Change fusing unit. 5 Change MFPB. 6 Change DCPU.
