Trouble type• C2153: Transfer belt spacing fault at K pressure switching
RankB
Trouble detection conditionThe 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)
