Error codes konica minolta

Code: C3822, C3825
Description:
• C3822: Fusing abnormally low temperature detection (Edge of the heating roller)
• C3825: Fusing abnormally low temperature detection (Middle of the heating roller)
• C3822: Detected temperature of the heating roller temperature sensor/2 (TEMS2) goes below a given temperature for a given period of time consecutively.
• C3825: Detected temperature of the heating roller temperature sensor/1 (TEMS1) goes below a given temperature for a given period of time consecutively.
Causes:
• Fusing unit • C3825: Heating roller temperature sensor/1 (TEMS1) • C3822: Heating roller temperature sensor/2 (TEMS2) • 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-relay CN512-MFPB CN31E for proper connection and correct as necessary. 4. Replace the fusing unit. 5. MFPB F3E conduction check 6. Replace MFPB.
