BSD 10.1 - Fusing Heat Control
•
After the Main Lamp turned On during warm up, the Control Thermistor did not detect
READY temperature within the specified time.
•
After the Main Lamp turned On during standby, the Control Thermistor did not detect a
specific temperature within the specified time.
•
After the Sub Lamp turned On during standby, the Control Thermistor did not detect a
specific temperature within the specified time.
•
After the empty rotation started, the Control Thermistor did not detect the empty rotation
finishing temperature within the specified time.
•
After the Main Lamp turned On during printing, the Control Thermistor did not detect a
specific temperature within the specified time.
•
After the Sub Lamp turned On during printing, the Control Thermistor did not detect a spe-
cific temperature within the specified time.

Procedure
NOTE: When this fault occurs, NVM location 744-005 is set to 1, 2, or 3, depending on the
fault. You must reset this location to 0 in order to clear the fault.
Check for paper on the Fuser. The Fuser has no paper wrapped round it.
Y
N
Remove the paper.
Check the installation of the Fuser Unit. The Fuser Unit is securely installed.
Y
N
Install the Fuser Unit securely.
Remove the Fuser Unit. Check the conductivity of the contact points of the Thermostat. The
contact points are connected.
Y
N
Replace the Fuser Unit (
PL 7.1
).
Check the resistance of the Main Lamp between
J621
-6 and
J621
-7 for an open circuit or a
short circuit (
BSD 10.1
). The resistance of the Main Lamp is 100 ohms or lower.
Y
N
Replace the Fuser Unit (
PL 7.1
).
Check the resistance of the Sub Lamp between
J621
-2 and
J621
-7 for an open circuit or a
short circuit (
BSD 10.1
). The resistance of the Sub Lamp is 100 ohms or lower.
Y
N
Replace the Fuser Unit (
PL 7.1
).
Check the resistance of the Control (Center) Thermistor between
J621
-5 and
J621
-1 (
BSD
10.1
). There is no open circuit in the Center STS and the resistance is 3k ohms or higher.
Y
N
Replace the Fuser Unit (
PL 7.1
).
Check the resistance of the Rear Thermistor between
J621
-7 and
J621
-3 (
BSD 10.1
). The
resistance is 3k ohms or higher.
Y
N
Replace the Fuser Unit (
PL 7.1
).
Check the wire between
P/J411
-B7 and
J621
-7 for an open circuit or a short circuit (
BSD
10.1
). The wire between
P/J411
and
J621
is conducting without an open circuit or a
short circuit.
Y
N
Repair the open circuit or short circuit.
Check the wire between
P/J414
and
P530
for an open circuit or a short circuit (
BSD 10.1
).
The wire between
P/J414
and
P530
conducts and if free of a short circuit.
Y
N
Repair the open circuit or short circuit.
Replace the Fuser Unit (
PL 7.1
). If the problem persists, replace the AC Drive PWB (
PL 18.2
)
If the problem persists, replace the MCU PWB (
PL 18.2
).
