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)  • Expansion control board (EXCB)  • MFP board (MFPB)

 Procedure

1. Check the connector between M3-MFPB CN14E 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 CN15E for proper connection and correct as necessary.
4. Check the connector between CL5-relay CN118-EXCB CN8 for proper connection and correct as necessary.
5. PS39 I/O check, sensor check
   • Control signal: MFPB CN15E<B>-10 (ON)
   • Location of electrical component: C658/C558 18-C, C458 21-C
6. CL5 operation check
   • Control signal: EXCB CN8<A>-4 (CL5_REM)
   • Location of electrical component: 25-T
7. M3 operation check
   • Control signal: MFPB CN14E-9 (REM), MFPB CN14E-12 (LOCK)
   • Location of electrical component: 2-C
8. Replace M3. (Part# A2X0M10300)
9. Replace EXCB. (Part# A79JH00500)
10. MFPB F6E conduction check
11. Replace MFPB. (C458 Part# A79MH02102 / C558 or C658 Part # A79JH02102)
