Error codes konica minolta

Code: C3922, C3925, C3926
Description:
• C3922: Fusing sensor wire breaks detection (Edge of the heating roller) • C3925: Fusing sensor wire breaks detection (Middle of the heating roller) • C3926: Fusing sensor wire breaks detection (Center of the heating roller)
• C3922: The maximum value and minimum value of detected temperature of the heating roller temperature sensor/2 (TEMS2) is compared after a lapse of given time from starting of warm up and the gap between the value of maximum and minimum is below a given temperature. • C3925: The maximum value and minimum value of detected temperature of the heating roller temperature sensor/1 (TEMS1) is compared after a lapse of given time from starting of warm up and the gap between the value of maximum and minimum is below a given temperature. • C3926: The maximum value and minimum value of detected temperature of the heating roller temperature sensor/3 (TEMS3) is compared after a lapse of given time from starting of warm up and the gap between the value of maximum and minimum is below a given temperature.
Causes:
• Fusing unit • C3925: Heating roller temperature sensor/1 (TEMS1) • C3922: Heating roller temperature sensor/2 (TEMS2) • C3926: Heating roller temperature sensor/3 (TEMS3) • MFP board (MFPB)
Remedy:
1. Check the fusing unit for correct installation (whether it is secured in position). 2. Check the open/close operation of the upper right door. 3. Check the connector between TEMS1, TEMS2, TEMS3-relay CN512-MFPB CN31E for proper connection and correct as necessary. 4. Replace the fusing unit. 5. MFPB F3E conduction check 6. Replace MFPB.
