10-391 Fail Unit Failure RAP
The Failure detection circuit (hardware) indicated an abnormal operation but a failure did not
occur for the Heat Roll, Pressure Roll and External Heat Roll.
Initial Actions
Refer to BSD 10.2, 10.3, and 10.12 for the following procedure.
Procedure
Close the Drawer. Cheat the Front Door Interlock. Switch on the power.
The Heat Roll Heater
Rod illuminates after self-test completes.
Y
N
Go to the
OF10-3 Heat Roll AC Power RAP
Enter
dC330 010-031 Pressure Roll Heater Rod On
. Press
Start
.
The Pressure Roll Heater
Rod illuminates momentarily.
Y
N
Go to the
OF10-4 Pressure Roll AC Power RAP
Enter
dC330 010-029 External Heat Roll Lamp
. Press
Start
.
ACH is measured momen-
tarily between
P/J100
-1 on the SSR and
P/J15
-1 on the AC Driver PWB (ACN into AC
Driver PWB).
Y
N
Go to the
OF10-5 External Heat Roll AC Power RAP
.
Open the drawer. Remove the cheater on the Front Door Interlock. Measure the resistance
across the External Heat Roll Heater Rod (
P/J193
-1 to
P/J196
-1).
The resistance is less
than 10 Ohms.
Y
N
Replace the External Heat Roll Heater Rod (
PL 8.8
).
Measure the resistance across the External Heat Roll Thermostat.
The resistance is less
than 10 Ohms.
Y
N
Replace the External Heat Roll Thermostat (
PL 8.8
).
Check the following:
•
Disconnect the connectors to the components (Heat Roll, Pressure Roll, and External
Heat Roll Thermostats; AC Driver PWB; SSR; and the IOT Drive PWB). Check for broken,
bent, or dirty pins. Disconnect, then reconnect, the connectors several times to remove
contaminants due to oxidation.
•
Check the Heat Roll Control Thermistor (
PL 8.4
), Pressure Roll Control Thermistor (
PL
8.6
), or External Heat Roll Control Thermistor (
PL 8.8
). Replace the Thermistor if worn, or
dirty.
•
If no problem is found with the connectors, replace the SSR (
PL 9.3
).
•
If the problem continues, replace the IOT Drive PWB (
PL 9.2
).
•
If the problem persists, replace these components in the following order until the problem
is resolved: IOT CPU PWB (
PL 9.2
), IOT NVM PWB (
PL 9.2
).
10-398 Fuser Fan Failure RAP
The Fuser Fan Failed.
NOTE:
This status code is stored in NVM location 772-017 and cannot be reset by Power Off/
On. To reset this code, enter Diagnostics and change the value in NVM location 772-017 Fuser
Fan from “1” to “0”.
Initial Actions
Refer to BSD 10.1 and 10.12 for the following procedure.
Ensure that connector
P/J11B
is seated correctly on the AC Driver PWB and there are no obvi-
ous crimped or broken wires.
Procedure
Switch the power Off then On. Enter
dC330 010-004 Fuser Fan-Low Speed
. Press
Start
.
Press
Stop
.
The Fuser Fan switches from High Speed to Low Speed and back to High
Speed.
Y
N
+12 VDC is measured between
P/J11B
-13 on the AC Driver PWB and GND.
Y
N
Go to
Flag 9
on BSD 10.1 and check the harness for an open circuit. If the harness is
good, replace the AC Driver PWB (
PL 9.3
).
+12 VDC is measured between
P/J11B
-13 and
P/J11B
-14 on the AC Driver PWB.
Y
N
Replace the AC Driver PWB (
PL 9.3
).
Approximately +4 VDC is measured between
P/J11B
-12 on the AC Driver PWB and
GND.
Y
N
Go to
Flag 8
and
Flag 9
on BSD 10.1 and check the harness for an open circuit. If
the harness is good, replace the Fuser Fan (
PL 10.2
).
Approximately +4 VDC is measured between
P/J419B
-13 on the IOT Drive PWB and
GND.
Y
N
Go to
Flag 11
on BSD 10.1 and check the harness for an open circuit. If the harness
is good, replace the AC Driver PWB (
PL 9.3
). If the problem continues, replace the
IOT Drive PWB (
PL 9.2
).
Replace the Fuser Fan (
PL 10.2
).
Less than +1.0 VDC is measured between
P/J419B
-12 on the IOT Driver and GND.
Y
N
Go to
Flag 10
on BSD 10.1 and check the harness for a short circuit. If the harness is
good, replace the Fuser Fan (
PL 10.2
). If the problem continues, replace the IOT Drive
PWB (
PL 9.2
).
Replace the Fuser Fan (
PL 10.2
). If the problem continues, replace the IOT Drive PWB (
PL
9.2
).
