Trouble typeC2154: Transfer belt contact fault at all pressure switching
RankB
Trouble detection conditionC2154: The 1st transfer pressure sensor (PS39) does not detect “switch from retraction to pressure” 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)
• CPU board (CPUB)
• Base board (BASEB)

Procedure

  1. Check the connector between M3-BASEB CN19E 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-BASEB CN13E for proper connection and correct as necessary.
  4. Check the connector between CL5-relay CN118-EXCB CN14EX for proper connection and correct as necessary.
  5. Check the connector between EXCB CN2EX-BASEB CN12E for proper connection and correct as necessary.
  6. Check CPUB for proper installation and correct as necessary.
  7. PS39 I/O check, sensor check
