CHAPTER 6 TROUBLESHOOTING
14. Faulty swing motor (related to PI20)
15. Faulty tray-1 lift motor (related to PI8)
16. Faulty tray-2 lift motor (related to PI25)
Checks
Check the swing motor clock
sensor. Is the sensor normal?
Does the voltage of the swing
motor between J11-6 and -7
on the finisher controller PCB
reach 24 V at a specific
rotation timing?
Cause
Swing motor clock
sensor (PI20)
Finisher controller PCB
Step

Yes/No
No
No
Yes
Action
Replace the sensor.
Replace the finisher
controller PCB.
Check the wiring from
the motor to the
finisher controller
PCB. If normal,
replace the motor.
Checks
Check the tray-1 home
position sensor. Is it normal?
Check the tray-1 lift
mechanism. Is the mechanism
normal?
Is the tray-1 lift motor
supplied with 24 VDC by the
finisher controller PCB as
soon as the tray is driven?
Check the wiring from the
finisher controller PCB to the
tray-1 lift motor. Is the wiring
normal?
Cause
Tray-1 home position
sensor (PI8)
Tray-1 lift mechanism
Finisher controller PCB
Wiring
Tray-1 lift motor (M5)
Step

Yes/No
No
No
No
No
Yes
Action
Replace the sensor.
Correct the
mechanism.
Replace the finisher
controller PCB.
Correct the wiring.
Replace the tray-1 lift
motor.
Checks
Check the tray-2 lift
mechanism. Is the mechanism
normal?
Is the tray-2 lift motor
supplied with 24 VDC by the
finisher controller PCB as
soon as the tray is driven?
Check the wiring from the
finisher controller PCB to the
tray-2 lift motor. Is the wiring
normal?
Cause
Tray-2 lift mechanism
(PI25)
Finisher controller PCB
Wiring
Tray-2 lift motor (M10)
Step
1

3
Yes/No
No
No
No
Yes
Action
Correct the
mechanism.
Replace the finisher
controller PCB.
Correct the wiring.
Replace the tray-2 lift
motor.
Note :
If the tray cannot be lowered because it makes contact with something under the Finisher, this error occurs.
Therefore, tell the users not to place anything under the tray.
