LL.43 Fuser Overtemperature
RAP
NOTE: Refer to BSD 10.1 while using this
RAP.
WARNING
Dangerous Voltage
LL.43 is displayed when the logic detects that
there is a problem with the Fuser temperature
and an overtemperature condition has caused
the Thermal Fuse, A23F1, to open.
Initial Actions
• Ensure that the following connectors are
properly seated:
a. Driver PWB A2J213 / A2P213
fa. Driver PWB A2J201 / A2P201
c. Xerographics Module A23J2 / A23P2
d. Thermistor Pad Assembly J5 / A23P5
• Ensure that both cooling fans are working.
If not, go to BSD 1.3 to repair the cooling
fans circuit.
• Ensure that all interlocks are closed.
Procedure
Connect the (+) meter lead to the Driver PWB
A2P201-1 and the (-) meter lead to ground.
There is +26 VDC present.
Y N
Check continuity through the Overtemp-
erature Fuse, A23F1, as follows:
a) Disconnect the BLU and GRY wires
from the fuse.
b) Set the meter to measure continuity.
c) Connect the meter across the fuse
terminals.
The fuse has continuity
A B C
A B C
Switch off the printer and disconnect
the Power Cord. Replace the Thermal
Fuse, A23F1, PL 10.4.
Perform the following steps to
determine the cause for the fuse to
open:
a) Disconnect the BLU and WHT
wires from the Fuser Triac, A1Q1.
b) Set the meter to measure 2K
ohms. Measure the resistance
across the Fuser Triac
connections from which the wires
were removed. If the resistance is
not infinite, replace the Fuser
Triac, A1Q1.PL 1.2.
c) Measure the resistance from each
of the Fuser Triac connections
from which the wires were
removed to ground. If the
resistance is not infinite, replace
the Fuser Triac, A23Q1, PL 1.2.
V
Connect the (+) meter lead to the Driver
PWB, A2P201-3 and the (-) meter lead to
ground.
There is +26 VDC present.
N
Replace the Driver PWB, A2, PL 1.1.
Check the BLU and GRY wires between
the Thermal Fuse, A23F1, and the Driver
PWB, A2 for continuity.
The wires have continuity.
Y N
Repair the wires.
r
A D
Disconnect A23P5 from the Thermistor
Pad Assembly J5. Set the meter to
measure 200K ohms. Connect the (+)
meter lead to the Thermistor Pad
Assembly J5-1 and the (-) meter lead to
J5-2.
The resistance is less that 200K ohms.
Y N
Replace the Thermistor Pad Assembly
PL 10.4.
Check the YEL and GRN wires between
the Fuser Thermistor and the Main PWB,
A1 for continuity.
The wires have continuity.
Y N
I Repair the wires.
Replace the Driver PWB, A2, PL 1.1. If
the problem persists, replace the Main
PWBA1.PL 1.1.
Connect the (+) meter lead to the Driver PWB,
A2P213-3 and the (-) meter lead to ground.
Enter Diagnostic code [1009] to turn on the
Fuser Power Relay, A1K1.
The voltage changes from +26 VDC to less
than 1 VDC when the Fuser Power Relay is
turned on.
Y N
Check the BRN and ORN wires between
the Fuser Power Relay, A1K1, and the
Driver PWB, A2 for continuity.
The wires have continuity.
Y N
I Repair the wires.
Replace the Driver PWB, A2, PL 1.1. If
the problem persists, replace the Main
PWB, A1, PL 1.1.
Replace the Fuser Power Relay, A1K1, PL
1.2.
