Error codes konica minolta

Code: C3102
Description:
Heating roller failure to turn. During any state other than printing operation, the hard latch signal from one or both of the heating roller rotation latch detection 1 and the heating roller rotation latch detection 2 is turned ON.
Causes:
• Fusing unit • Heating roller rotation sensor (PS56) • Fusing motor (M30) • DC power supply (DCPU) • MFP board (MFPB)
Remedy:
1. Check the fusing unit for proper installation and correct as necessary. 2. Check the connector between M30-MFPB CN28E for proper connection and correct as necessary. 3. Check the connector of M30 for proper drive coupling and correct as necessary. 4. Check the connector between the fusing unit-relay CN260-MFPB CN21E for proper connection and correct or change as necessary. 5. PS56 I/O check, sensor check • Control signal: MFPB CN21E-8 (ON) • Location of electrical component: 11-C 6. M30 load check • Check code: 45 • Multi code: 1, 2, 3, 4, 5, 6 • Control signal: MFPB CN28E-1 (DC24V), MFPB CN28E-4 (REM), MFPB CN28E-7 (LOCK) • Location of electrical component: 7-K 7. Replace M30. 8. Replace the fusing unit. 9. MFPB F16E conduction check 10. Replace MFPB. 11. DCPU F851 conduction check. 12. Replace DCPU.
