Troubleshooting
Rotation abnormality of the Sub Motor.
Procedure
Enter CE Mode and turn Digital Output[042-003] ON.. Does the Sub Motor rotate?
YN
Check the power supply line of the Sub Motor (+24VDC).. Is the Sub Motor power supply nor-
mal?
YN
Check the power supply circuit to the Sub Motor.
Turn OFF the power and check the following:
• Disconnection, shortage or contact failure of wire between Sub Motor J209 and DRIVE PWB
J412.
• Disconnection, shortage or contact failure of wire between DRIVE PWB J1 and ESS PWB J6.
• The Drive Gear for wear, damage, and bearing blockage.
• Load towards the Sub Motor.
If no problem is found, replace the following parts in sequence:
• Sub Motor (PL 3.4)
• DRIVE PWB (PL 18.2)
Press [Stop] and turn OFF the power. Check for disconnection, shortage or contact failure of wire
between Sub Motor J209-6 and DRIVE PWB J412-3.
If no problem is found, replace the following parts in sequence:
• DRIVE PWB (PL 18.2)
• ESS PWB (PL 18.2)
• Sub Motor (PL 3.4)

BSD-ON:CH10.4
Abnormality in Fusing Exhaust Fan rotation.
Procedure
Enter CE Mode and turn Digital Output[042-010] ON.. Does the Fusing Exhaust Fan rotate?
YN
Check the power supply line of the Fusing Exhaust Fan (+24VDC).. Is the Fusing Exhaust Fan
power supply normal?
YN
Check the power supply circuit to the Fusing Exhaust Fan.
Turn OFF the power and check the following:
• Disconnection, shortage or contact failure of wire between the Fusing Exhaust Fan and DRIVE
PWB J202.
• Disconnection, shortage or contact failure of wire between DRIVE PWB J1 and ESS PWB J6.
• Load towards the Fusing Exhaust Fan.
