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 CN11E 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 CN24-MFPB CN7E for proper connection and correct as necessary.
4. Check the connector between CL5-relay CN29-MFPB CN12E for proper connection and correct as necessary.
5. PS39 I/O check, sensor check
   • Control signal: MFPB CN7E<B>-13 (ON)
