03/02 Level 2 Troubleshooting
U9-31 MCU/SW PWB Failure (BSD 3.1C)
If Power OFF/ON does not solve the problem, replace the
MCU/SW PWB (PL7.2).
U9-32 MCU/SW PWB Failure (BSD 3.1C)
If Power OFF/ON does not solve the problem, replace the
MCU/SW PWB (PL7.2).
U9-33 MCU/SW PWB Failure (BSD 3.1C)
If Power OFF/ON does not solve the problem, replace the
MCU/SW PWB (PL7.2).
U9-41 MCU/SW PWB Failure (BSD 3.1C)
If Power OFF/ON does not solve the problem, replace the
MCU/SW PWB (PL7.2).
H5-61 FINISHER Interface Abnormal (BSD 3.1E)
Check between the MCU/SW PWB and FINISHER CONT PWB
for an open wire or poor contact. If no problem is found, replace
the MCU/SW PWB (PL7.2) and FINISHER CONT PWB
(PL13.16) in this order.
H5-62 FINISHER Interface Abnormal (BSD 3.1E)
Check between the MCU/SW PWB and FINISHER CONT PWB
for an open wire or poor contact. If no problem is found, replace
the MCU/SW PWB (PL7.2) and FINISHER CONT PWB
(PL13.16) in this order.
H5-63 FINISHER Interface Abnormal (BSD 3.1E)
Check between the MCU/SW PWB and FINISHER CONT PWB
for an open wire or poor contact. If no problem is found, replace
the MCU/SW PWB (PL7.2) and FINISHER CONT PWB
(PL13.16) in this order.
H5-64 FINISHER Interface Abnormal (BSD 3.1E)
Check between the MCU/SW PWB and FINISHER CONT PWB
for an open wire or poor contact. If no problem is found, replace
the MCU/SW PWB (PL7.2) and FINISHER CONT PWB
(PL13.16) in this order.

Y
N
Close the TOP COVER or FRONT DOOR.
Enter Diag. Mode and execute Chain12 Func29.
Does the STAPLE MOTOR rotate?
Y
N
Check between CN10 of the FINISHER CONT PWB and
the STAPLER UNIT for an open wire or poor contact.
The connection is normal?
Y
N
Repair an open wire or poor contact.
Replace the STAPLE HEAD. (PL13.3)
Turn the power off and remove the STAPLE HEAD. Turn the
power on with the connector connected and execute Chain12
Func16. Turn the STAPLE MOTOR gear manually.
Does the display change (H/L)?
Y
N
Check between CN10 of the FINISHER CONT PWB and
STAPLER UNIT for an open wire or poor contact.
The connection is normal.
Y
N
Repair an open wire or poor contact.
Replace the STAPLE HEAD. (PL13.3)
