• Code: E584-8001
• Description: shutter unit error (Finisher-R1/R2)
  The shutter open sensor does not go off (i.e., the shutter is not closed).
• 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?
