Trouble typeC2152: Transfer belt fault at initial position return
RankB
Trouble detection conditionThe 1st transfer pressure sensor (PS39) is unable to detect “switch from retraction to pressure” or “switch from pressure to retraction” within a given period time after the 1st transfer pressure clutch (CL5) has stared engagement during an initial position return.
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.
