C2153 (bizhub C368/C308/C258)

Contents

Trouble type	• C2153: Transfer belt spacing fault at K pressure switching
Rank	B
Trouble detection condition	The 1st transfer pressure sensor (PS39) does not detect switch from pressure to retraction within a given period time after 1st transfer pressure clutch (CL5) has stared engagement.
Trouble isolation	–
Relevant electrical parts	• Fusing motor (M3)  • 1st transfer pressure clutch (CL5)  • 1st transfer pressure sensor (PS39)  • MFP board (MFPB)

 Procedure

1. Check the connector between M3-MFPB CN8E for proper connection and correct as necessary.
2. Check the connector of M3 for proper drive coupling and correct as necessary.
3. Check the connector between PS39-relay CN113-MFPB CN15EB for proper connection and correct as necessary.
4. Check the connector between CL5-relay CN118-MFPB CN15EA for proper connection and correct as necessary.
5. PS39 I/O check, sensor check
   • Control signal: MFPB CN15EB-17 (ON)
   • Location of electrical component: 10-C
6. CL5 operation check
   • Control signal: MFPB CN15EA-18 (ON)
   • Location of electrical component: 8-C
7. M3 operation check
   • Control signal: MFPB CN8E-9 (REM), MFPB CN8E-12 (LOCK)
   • Location of electrical component: 2-C
8. Replace M3. (Part# A7PUM10000)
9. MFPB ICP2E conduction check
10. Replace MFPB. (Part# A7PUH02123)
