Ink Melt Heaters Check
Procedure
Switch off the electricity to the machine,
GP 14
, and disconnect the power cord. Refer to
WD
1.2
. Disconnect PJ5AC from the
power supply unit
. Check the electrical resistance of the four
ink melt heaters by measuring the resistance across the pins of the PJ5AC harness as follows:
•
Black ink melt heater, pin 6 to pin 12. Expect a cold resistance of approximately 70-80
ohms.
•
Yellow ink melt heater, pin 6 to pin 13. Expect a cold resistance of approximately 70-80
ohms.
•
Cyan ink melt heater, pin 7 to pin 1. Expect a cold resistance of approximately 70-80
ohms.
•
Magenta ink melt heater, pin 7 to pin 11. Expect a cold resistance of approximately 70-80
ohms.
•
Check that pin 7 to chassis is open circuit.
•
Check that pin 6 to the chassis is open circuit.
The measured resistances are correct.

Thermal Cutout Check
Registration / Pre-Heaters Check
Procedure
Switch off the electricity to the machine,
GP 14
, and disconnect the power cord. Refer to
WD
1.2
. Disconnect PJ5AC from the
power supply unit
. Check the electrical resistance of the regis-
tration/pre-heaters by measuring the resistance across the pins of the PJ5AC harness as fol-
lows:
•
Registration pre-heater 1, pin 3 to pin 9. Expect a cold resistance of approximately 50-60
ohms.
•
Registration pre-heater 2, pin 2 to pin 8. Expect a cold resistance of approximately 50-60
ohms.
•
Check that pin 8 to the chassis is open circuit.
•
Check that pin 9 to the chassis is open circuit.
The measured resistances are correct.
Y
N
Go to
WD 1.2
. Check the wiring between PJ5AC on the
power supply unit
, and PJ140 to
the registration preheat assembly. Repair the wiring as necessary, refer to
REP 1.1
. As
necessary, install a new registration preheat assembly
PL 88.10 Item 1
.
The registration/pre-heaters are good. If necessary, install a new power supply unit,
PL 1.15
Item 2
.
Thermal Cutout Check
Procedure
Switch off the electricity to the machine,
GP 14
, and disconnect the power cord. Refer to
WD
1.2
. Disconnect PJ5AC harness on the
power supply unit
. Check the continuity of the thermal
cutouts on the thermal cutout PWB, by measuring the resistance across the pins of the PJ5AC
harness as follows:
•
cutout for drum heater 1, pin 4 to pin 14. Expect a short circuit.
•
cutout for drum heater 2, pin 5 to pin 18. Expect a short circuit.
•
Check that pin 4 and 5 to the chassis is open circuit.
The measured resistances are correct.

N
Go to
WD 1.2
. Check the wiring between PJ5AC on the
power supply unit
and PJ140 to
the thermal cutout PWB,
PL 88.10 Item 11
. Repair as necessary, refer to
REP 1.1
. As
necessary, install a new thermal cutout PWB,
PL 94.20 Item 11
.
The thermal cutouts are good. Refer to
WD 9.4
. Switch on the electricity to the machine,
GP
14
, and check the voltage on PJ902 pin 1 or pin 2 on the
drum driver PWB
is greater than
+2.5V. Check the voltage on PJ902 pin 33 on the
drum driver PWB
