• Code: E540-8005
• Description: There is an upper tray ascent/decent error. (finisher)
  The lock detection signal turns OFF 150 ms after the lock detection signal turned ON
• Remedy: 1. Check the No. 1 tray area sensors 1 through 3. Are they normal? 2. Check the wiring between the finisher controller PCB and the No. 1 tray shift motor. Is it normal? 3. Is there a fault in the tray ascent/descent mechanism? 4. Try replacing the No. 1 tray 1 paper surface sensor tray shift motor. Is the problem corrected?

• Code: E540-8006
• Description: There is an upper tray ascent/decent error. (finisher)
  The lock detection signal does not turn ON when the tray 1 shift motor has been driven for 1 second.
• Remedy: 1. Check the No. 1 tray area sensors 1 through 3. Are they normal? 2. Check the wiring between the finisher controller PCB and the No. 1 tray shift motor. Is it normal? 3. Is there a fault in the tray ascent/descent mechanism? 4. Try replacing the No. 1 tray 1 paper surface sensor tray shift motor. Is the problem corrected?

• Code: E540-8007
• Description: There is an upper tray ascent/decent error. (finisher)
  The lock detection signal does not turn OFF when the tray 1 shift motor is at a stop.
• Remedy: 1. Check the No. 1 tray area sensors 1 through 3. Are they normal? 2. Check the wiring between the finisher controller PCB and the No. 1 tray shift motor. Is it normal? 3. Is there a fault in the tray ascent/descent mechanism? 4. Try replacing the No. 1 tray 1 paper surface sensor tray shift motor. Is the problem corrected?

• Code: E542-0003
• Description: There is a lower tray ascent/descent error. (finisher)
  The safety switch has activated
• Remedy: 1. Check the No. 2 tray area sensors 1 through 3. Are the sensors normal? 2. Check the wiring between the finisher controller PCB and the No. 2 tray shift motor. Is it 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: There is a lower tray ascent/descent error. (finisher)
  There is a fault in the lower tray ascent/descent motor clock signal.
• Remedy: 1. Check the No. 2 tray area sensors 1 through 3. Are the sensors normal? 2. Check the wiring between the finisher controller PCB and the No. 2 tray shift motor. Is it 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: E542-8002
• Description: There is a lower tray ascent/descent error. (finisher)
  There is an area error.
• Remedy: 1. Check the No. 2 tray area sensors 1 through 3. Are the sensors normal? 2. Check the wiring between the finisher controller PCB and the No. 2 tray shift motor. Is it 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: There is a shutter unit error. (finisher)
  The shutter open sensor does not go on. (The shutter does not open.)
• Remedy: 1. Check the shutter home position sensor. Is it normal? 2. Check the wiring between the finisher controller PCB and the stack feeding motor and between the finisher controller PCB and the shutter open/close clutch. Is it normal? 3. Is there a fault in the shutter mechanism? 4. Try replacing the stack edging motor and the shutter open/close clutch. Is the problem corrected?

• Code: E584-8001
• Description: There is a shutter unit error. (finisher)
  The shutter open sensor fails to go off. (The shutter does not close.)
• Remedy: 1. Check the shutter home position sensor. Is it normal? 2. Check the wiring between the finisher controller PCB and the stack feeding motor and between the finisher controller PCB and the shutter open/close clutch. Is it normal? 3. Is there a fault in the shutter mechanism? 4. Try replacing the stack edging motor and the shutter open/close clutch. Is the problem corrected?
