• Code: E537-8002
• Description: rear alignment error (Finisher-R1/R2)
  The home position sensor does not go on even when the swing motor has rotated for a specific period of time.
• Remedy: 1) Check the post-aligning plate home position sensor. Is the sensor normal? 2) Check the wiring between the finisher controller PCB and the post-aligning plate motor. Is the wiring normal? 3) Check the path of the aligning plate. Is there a mechanical obstacle? 4) Try replacing the post-aligning plate motor. Is the problem corrected?

• Code: E540-8001
• Description: upper tray ascent/descent error (Finisher-R1/R2)
  upper tray ascent/descent motor clock error
• Remedy: 1) Check the No. 1 tray area sensors 1 through 3. Are the sensors normal? 2) Check the wiring between finisher controller PCB and the No. 1 tray shift motor. Is the wiring normal? 3) Is there a fault in the ascent/descent mechanism of the tray? 4) Try replacing the No. 1 tray shift motor. Is the problem corrected?

• Code: E540-8002
• Description: upper tray ascent/descent error (Finisher-R1/R2)
  area error
• Remedy: 1) Check the No. 1 tray area sensors 1 through 3. Are the sensors normal? 2) Check the wiring between finisher controller PCB and the No. 1 tray shift motor. Is the wiring normal? 3) Is there a fault in the ascent/descent mechanism of the tray? 4) Try replacing the No. 1 tray shift motor. Is the problem corrected?

• Code: E540-8003
• Description: upper tray ascent/descent error (Finisher-R1/R2)
  safety switch activation
• Remedy: 1) Check the No. 1 tray area sensors 1 through 3. Are the sensors normal? 2) Check the wiring between finisher controller PCB and the No. 1 tray shift motor. Is the wiring normal? 3) Is there a fault in the ascent/descent mechanism of the tray? 4) Try replacing the No. 1 tray shift motor. Is the problem corrected?

• Code: E542-0003
• Description: lower tray ascent/descent error (Finisher-R1/R2)
  safety switch activation
• Remedy: 1) Check the No. 2 tray sensors 1 through 3. Are the sensors normal? 2) Check the wiring between the finer controller PCB and the No. 2 tray shift motor. Is the wiring normal? 3) Is there a fault in the tray ascent/descent mechanism? 4) Try replacing the No. 2 tray shift motor. Is the problem corrected?

• Code: E542-8001
• Description: lower tray ascent/descent error (Finisher-R1/R2)
  lower tray ascent/descent motor clock error
• Remedy: 1) Check the No. 2 tray sensors 1 through 3. Are the sensors normal? 2) Check the wiring between the finer controller PCB and the No. 2 tray shift motor. Is the wiring normal? 3) Is there a fault in the tray ascent/descent mechanism? 4) Try replacing the No. 2 tray shift motor. Is the problem corrected?

• Code: E584-0002
• Description: shutter unit error (Finisher-R1/R2)
  The shutter open/closed sensor does not go on (i.e., the shutter does not open).
• Remedy: 1) Check the shutter home position sensor. Is the sensor normal? 2) Check the wiring between the finisher controller PCB and the stack edging motor and between the finisher controller PCB and the shutter open/close clutch. Is the wiring normal? 3) Is there a fault in the shutter mechanism? 4) Try replacing the stack edging motor or the shutter open/close clutch. Is the problem corrected?
