10-380 Fuser Over Temperature RAP
10-315 The difference between 2 consecutive thermistor readings exceeds a given value.
10-320 During standby or run mode, the thermistor reading is not within the target temperature
range.
10-321 Over temperature during standby mode, the thermistor reading is not within the target
temperature range
10-323 Over temperature during run mode, the thermistor reading is not within the target tem-
perature range.
10-340 Fuser temperature sensor A reading monitors above its normal operating temperature.
10-350 The hardware comparator detects a fuser reading greater than 240 degrees centigrade
or a short circuit thermistor.
10-360 Fuser temperature sensor B reading is greater than the normal operating temperature.
10-365 The fuser module is above the recommended operating temperature.
10-380 The fuser delta value between the temperature sensors A and B is to high.
Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14
. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
WARNING
Do not touch the fuser while it is hot.
•
If a number of 10-321 fault codes, are in the fault history. Check if the customer has been
running transparency jobs of nominal papers at card stock settings. This fault can be gen-
erated when the temperature changes between the standby and run. This is a normal
function of the machine and should not effect the customer operation.
•
Check that the fuser temperature NVM settings in
dC131
, are set to default. Refer to NVM
location 10-028 though to 10-061 and location 08-282 through to 08-295. Ensure that the
values are set to the default level. If the values are not at default then, 10-320, 10-321,
10-340 and 10-360 may appear in the fault log.
•
Check the fuser module connector,
Figure 1
.
•
Check the fuser connector assembly,
Figure 2
.
•
Check that the photorecptor fan,
PL 9.25 Item 7
is working correctly and that the direction
of air flow is into the machine, refer to the
09C
Photoreceptor Fan RAP. Check that the
intake grille at the rear of the machine is not blocked and there is not a heat source such
as a radiator immediately behind the machine. Check that the photoreceptor duct,
PL
9.25 Item 5
and the lower duct,
PL 9.25 Item 8
are correctly installed.
Procedure
Switch off the machine, then switch on the machine,
GP 14
. The display shows Ready to
Copy.

N
Refer to
Figure 5
. Go to
Flag 1
. The voltage at the temperature sensors A and B should
be 2.9 volts when the sensors are cold. In standby mode the voltage should be 0.78 to
0.98 volts. Refer to:
•
P/J35
,
IOT PWB
.
•
01D
+3.3 V Distribution RAP.
•
01B
0V Distribution RAP
Before new components are installed, restore the NVM values to default.
Install new components as necessary:
•
Perform
OF7
IOT PWB Diagnostics RAP before a new IOT PWB is installed,
