Chapter 1515-78001 The home position sensor does not go off evenwhen the swing motor has rotated for a specificperiod of time.1. Check the aligning plate rear home positionsensor. Is it normal?2. Check the wiring between the finishercontroller PCB and the aligning plate rear motor.Is it normal?3. Is there a mechanical obstacle in the path of thealigning plate?4. Try replacing the aligning plate rear motor. Isthe problem corrected?8002 The home position sensor does not go on evenwhen the swing motor has rotated for a specificperiod of time.E540 There is an upper tray ascent/decent error. (finisher)8001 There is a fault in the upper tray ascent/descentmotor clock.1. Check the No. 1 tray area sensors 1 through 3.Are they normal?2. Check the wiring between the finishercontroller PCB and the No. 1 tray shift motor. Is itnormal?3. Is there a fault in the tray ascent/descentmechanism?4. Try replacing the No. 1 tray shift motor. Is theproblem corrected?8002 There is an area fault.8003 The safety switch has gone on.E542 There is a lower tray ascent/descent error. (finisher)8001 There is a fault in the lower tray ascent/descentmotor clock signal.1. Check the No. 2 tray area sensors 1 through 3.Are the sensors normal?2. Check the wiring between the finishercontroller PCB and the No. 2 tray shift motor. Is itnormal?3. Is there a fault in the tray ascent/descentmechanism?4. Try replacing the No. 2 tray shift motor. Is theproblem corrected?8002 There is an area error.0003 The safety switch has activated.E584 There is a shutter unit error. (finisher)8001 The shutter open sensor fails to go off. (The shutterdoes not close.)1. Check the shutter home position sensor. Is itnormal?2. Check the wiring between the finishercontroller PCB and the stack feeding motor andbetween the finisher controller PCB and theshutter open/close clutch. Is it normal?3. Is there a fault in the shutter mechanism?4. Try replacing the stack edging motor and theshutter open/close clutch. Is the problemcorrected?0002 The shutter open sensor does not go on. (Theshutter does not open.)E590 There is a punch motor error. (punch unit)8001 The punch home position sensor is not detectedeven when the punch motor has been driven for 200msec.- Check the punch home position sensor,horizontal registration motor, and punch driverPCB; thereafter, turn off and then back on themain power.8002 The puncher does not detect the punch homeposition sensor while the motor is at rest at time ofpunch motor initialization.E591 There is a punch dust sensor error. (punch unit)8001 The incoming light voltage is faulty in the presenceof light.- Turn off and then back on the main power.8002 The incoming light voltage is faulty in the absenceof light.E592 There is a punch horizontal registration sensor error. (punch unit)8001 The incoming light voltage is faulty in the presenceof light. (trailing edge sensor)- turn off and then back on the main power.8002 The incoming light is faulty in the absence of lightand voltage. (trailing edge sensor)8003 The incoming light voltage is faulty in the presenceof light. (horizontal registration sensor 1)8004 The incoming light voltage is faulty in the absenceof light. (horizontal registration sensor 1)8005 The incoming light voltage is faulty in the presenceof light. (horizontal registration sensor 2)8006 The incoming light voltage is faulty in the absenceof light. (horizontal registration sensor 2)8007 The incoming light voltage is faulty in the presenceof light. (horizontal registration sensor 3)8008 The incoming light voltage is faulty in the absenceof light. (horizontal registration sensor 3)8009 The incoming light voltage is faulty in the presenceof light. (horizontal registration sensor 4)800A The incoming light voltage is faulty in the absenceof light. (horizontal registration sensor 4)E593 There is a punch shift motor error.
