• Code: E531-0001
• Description: There is an error in stapling (finisher R1/R2).
  The home position sensor does not go off within a specific period of time after the stapler motor has started to rotate.
• Remedy: 1) Check the wiring between the finisher controller PCB and the stapler. Is the wiring normal? 2) Try replacing the stapler. Is the problem corrected?
