H5-83 FINISHER Failure (BSD12.11)
Enter Diag. Mode and excute Chain12 Func27 or 28.
Does the FINISHER TRAY ELEVATOR MOTOR rotate?
Y
N
Execute Chain12 Func27 or 28. Is each v24 VDC
between the FINISHER CONT PWB CN6-1/2(+) and
GND(-) ?
Y
N
Is the v24VDC between the FINISHER CONT
PWB CN1-1(+) and GND(-) ?
Y
N
P24VDC FIP.
Replace the FINISHER CONT PWB. (PL13.16)
Check between the FINISHER CONT PWB CN6 and TRAY
ELEVATOR MOTOR for an open wire or poor contact.
The connection is normal.
Y
N
Repair an open wire or poor contact.
Replace the TRAY ELEVATOR MOTOR. (PL13.18)
Execute Chain12 Func12. Push the Paper press lever up and
down. Does the display change (H/L)?
Y
N
Perform the General-purpose transmittion sensor FIP.
Remove the FINISHER RECIVING TRAY. Execute Chain12
Func13.
Turn the UPPER LIMIT SENSOR on and off with paper.
Does the display change?
Y
N
Perform the General-purpose transmittion sensor FIP.
Execute Chain12 Func14. Turn the NEAR FULL SENSOR on
and off with paper. Does the display change (H/L)?
Y
N
Perform the General-purpose transmittion sensor FIP.
Replace the MCU/SW PWB. (PL7.2)
H5-84 FINISHER Failure (BSD 12.10)
Check the removal of screw that secures (for delivery only)
STAPLE UNIT.
Check between the FINISHER CONT PWB CN10 and STAPLE
UNIT for an open wire or poor contact. If no problem is found,
replace the STAPLE HEAD (PL13.3), FINISHER CONT PWB
(PL13.16), and MCU/SW PWB(PL7.2) in this order.
H6-63 DADF Failure (BSD 3.1D)
If initialization does not clear the problem, replace the DADF
CONT PWB. (PLXX.X)
H6-64 DADF Failure (BSD 3.1D)
If initialization does not clear the problem, replace the DADF
CONT PWB. (PLXX.X)
H6-71 DADF Failure (BSD 3.1D)
Check between the IIT/IPS PWB and DADF CONT PWB for an
open wire or poor contact. If no problem is found, replace the
DADF CONT PWB(PLXX.X), IIT/IPS PWB(PL3.1), and MCU/SW
PWB(PL7.2) in this order.
H6-72 DADF Failure (BSD 3.1D)
Check between the IIT/IPS PWB and DADF CONT PWB for an
open wire or poor contact. If no problem is found, replace the
DADF CONT PWB(PLXX.X), IIT/IPS PWB(PL3.1), and MCU/SW
PWB(PL7.2) in this order.
H6-73 DADF Failure (BSD 3.1D)
Check between the IIT/IPS PWB and DADF CONT PWB for an
open wire or poor contact. If no problem is found, replace the
DADF CONT PWB(PLXX.X), IIT/IPS PWB(PL3.1), and MCU/SW
PWB(PL7.2) in this order.
H6-74 DADF Failure (BSD 3.1D)
Check between the IIT/IPS PWB and DADF CONT PWB for an
open wire or poor contact. If no problem is found, replace the
DADF CONT PWB (PLXX.X), IIT/IPS PWB(PL3.1), and
MCU/SW PWB(PL7.2) in this order.
H6-75 DADF Failure (BSD 3.1D)
Check between the IIT/IPS PWB and DADF CONT PWB for an
open wire or poor contact. If no problem is found, replace the
DADF CONT PWB(PLXX.X), IIT/IPS PWB(PL3.1), and MCU/SW
PWB(PL7.2) in this order.
H8-2 Page Memory Failure (BSD 3.1C)
Check the memory connector on the MCU/SW PWB. If no
problem is found, replace the MCU/SW PWB. (PL7.2)
H8-65 Page Memory Failure (BSD 3.1C)
Check the memory connector on the MCU/SW PWB. If no
problem is found, replace the MCU/SW PWB. (PL7.2)
H8-66 Page Memory Failure (BSD 3.1C)
Check the memory connector on the MCU/SW PWB. If no
problem is found, replace the optional memory.(PL7.2) If the
problem still does not recover, replace the MCU/SW
PWB.(PL7.2)
H8-67 Page Memory Failure (BSD 3.1C)
Check the memory connector on the MCU/SW PWB. If no
problem is found, replace the MCU/SW PWB. (PL7.2)
H8-68 Page Memory Failure (BSD 3.1C)
Check the memory connector on the MCU/SW PWB. If no
problem is found, replace the MCU/SW PWB. (PL7.2)
HD-01 Hard Disk Failure (BSD 3.1C)
Check between the HDC PWB and HDD for an open wire or
poor contact. If no problem is found, replace the HDD. (PL7.2)
HD-02 Hard Disk Failure (BSD 3.1C)
Check between the HDC PWB and HDD for an open wire or
poor contact. If no problem is found, replace the HDD. (PL7.2)
