Finisher Supply Check
Procedure
Verify that the machine is configured for a finisher and that the machine is ready to print. Refer
to
WD 1.4 and WD 9.4 . Check the Finisher On signal from PJDC2, pin 3 on the power supply
unit to PJ902, pin 3 on the drum driver PWB . The signal is good.
Y N
Switch off the electricity to the machine,
GP 14 , and disconnect the power cord. Repair
the wiring as necessary, REP 1.1 or install new wiring, PL 1.15 Item 10 . If necessary,
install new components:
•
Cord bracket assembly, PL 12.75 Item 4 .
• Power supply unit, PL 1.15 Item 2 .
• Drum driver PWB, PL 1.15 Item 4 .
• Drum driver power supply interface cable (PJ902), PL 1.15 Item 10 .
An HVF is installed.

N
Switch off the electricity to the machine,
GP 14 , and disconnect the power cord. Refer to
WD 1.1 and WD 12.1 . Check the wiring between PJ3AC on the power supply unit and
CN1 on the LCSS power supply module, PL 12.75 Item 2 . As necessary, repair the wiring,
REP 1.1 . If necessary, install new components:
• Cord bracket assembly, PL 12.75 Item 4 .
• LCSS power supply unit, PL 12.75 Item 2 .
• Power supply unit, PL 1.15 Item 2 .
NOTE: Verify that no short circuits exist between the line, neutral and ground on the
harness to the finisher, before a new
power supply unit is installed.
Switch off the electricity to the machine, GP 14 , and disconnect the power cord. Refer to WD
1.1 and WD 12.6. Check the wiring between PJ3AC on the power supply unit and CN1 on the
HVF power supply unit, PL 12.140 Item 1 . As necessary, repair the wiring, REP 1.1 . If neces-
sary, install new components:
•
Power cord, PL 12.140 Item 4 .
• HVF power supply unit, PL 12.140 Item 1 .
• Power supply unit, PL 1.15 Item 2 .
NOTE: Verify that no short circuits exist between the line, neutral and ground on the har-
ness to the finisher, before a new
power supply unit is installed.
Marking Unit Heater PWB Supply Check
Procedure
Refer to WD 1.1 and WD 9.8 , check the wiring between PJ4AC on the power supply unit and
PJ101 on the marking unit heater PWB . If necessary, repair the wiring, REP 1.1 .
Lower Umbilical Heater Check
Procedure
Switch off the electricity to the machine, GP 14 , and disconnect the power cord. Refer to WD
9.8 . Disconnect PJ701 from the marking unit heater PWB . Check the electrical resistance of
the lower umbilical heater, by measuring the resistance across pin 1 to pin 8 of the PJ701 har-
ness, expect a cold resistance of approximately 85-95 ohms. The measured resistance is
correct.

N
Go to
WD 9.8 . Check the wiring between PJ701 on the marking unit heater PWB and the
lower umbilical heater. Repair the wiring as necessary, refer to REP 1.1 . If necessary,
install new components:
• Umbilical, PL 91.25 Item 10 .
• Marking unit heater PWB, PL 92.10 Item 5 .
• Power supply unit, PL 1.15 Item 2 .
The lower umbilical heater is good. If necessary, install a new power supply unit, PL 1.15 Item 2 .
Head 1 Reservoir and Jetstack Heaters Check
Procedure
Switch off the electricity to the machine, GP 14 , and disconnect the power cord. Refer to WD
9.8 . Disconnect PJ701 from the marking unit heater PWB . Check the electrical resistance of
the head 1 reservoir and jetstack heaters, by measuring the resistance across the pins of the
PJ701 harness as follows:
•
Head 1 reservoir heater, pin 2 to pin 3. Expect a cold resistance of approximately 95-105
ohms.
• Head 1 first half jetstack heater, pin 5 to pin 4. Expect a cold resistance of approximately
495-505 ohms.
• Head 1 second half jetstack heater, pin 5 to pin 6. Expect a cold resistance of approxi-
mately 495-505 ohms.
• Check that pin 2 to ground and pin 5 to ground are open circuit.
The measured resistances are correct.
Y
N
Go to
WD 9.8 . Check the wiring between PJ701 on the marking unit heater PWB and the
head 1 reservoir and jet stack heater. Repair the wiring as necessary, refer to REP 1.1 . If
necessary, install a new printhead 1, PL 91.25 Item 2 .
The head 1 heaters are good. If necessary, install a new marking unit heater PWB, PL 92.10
Item 5 .
Head 3 Reservoir and Jetstack Heaters Check
Procedure
Switch off the electricity to the machine, GP 14 , and disconnect the power cord. Refer to WD
9.8 . Disconnect PJ701 from the marking unit heater PWB . Check the electrical resistance of
the head 3 reservoir and jetstack heaters, by measuring the resistance across the pins of the
PJ701 harness as follows:
•
Head 3 reservoir heater, pin 9 to pin 10. Expect a cold resistance of approximately 95-105
ohms.
• Head 3 first half jetstack heater, pin 12 to pin 11. Expect a cold resistance of approxi-
mately 495-505 ohms.
