Step Check Yes No
1
Initial check
Check the following for damage.
SENSOR EXIT actuator condition
FUSER ASY condition
FRONT COVER condition
CHUTE DUP IN condition
Transfer Unit (BTR) condition
Imaging Unit (PHD) condition
Replace the parts
concerned Go to step [2]
2
Check FUSER ASSY connector
Remove the FUSER ASSY connector, and check for broken
or curved pins.
With tool
Go to step [3]
Without tool
Go to step [4]
Replace the parts
concerned
3
Check SENSOR EXIT
Does SENSOR EXIT function normally?
Using SENSOR EXIT diagnostic tool, check by Diagnostic
Input Test.
Go to step [9] Go to step [4]
4
Check HARNESS FSR2 for signal
Push the paper in the FUSER ASSY
Is P/J138-3PIN <=> P/J138-2PIN 0VDC?
Go to step [6] Go to step [5]
5Check HARNESS FSR2 for continuity
J232 <=> J138 check continuous? Go to step [6]
Replace
HARNESS ASSY
FSR2
6Check HARNESS ASSY FRONT 1A for continuity
P138 <=> J13 check continuous? Go to step [7]
Replace
HARNESS ASSY
FRONT 1A
7
Check FUSER ASSY
Check if an error occurs though the FUSER ASSY was
replaced with a new one.
Go to step [9] End of work
8Check FUSER MOTOR for operation
Does the FUSER MOTOR run when printing 1 sheet?
Check the gears
for meshing
With tool
Go to step [9]
Without tool
Go to step [10]
9
Check FUSER MOTOR
Does FUSER MOTOR function normally?
Using FUSER MOTOR diagnostic tool, check by Diagnostic
Output Test.

HNB MCU Go to step [10]
10 Check PWBA HNB DRV for signal
Is P/J52-1PIN <=> P/J60-2PIN +24VDC? Go to step [11] Replace PWBA
HNB DRV
11
Check HARNESS ASSY DRV 1 for continuity
Check the following for continuity.
J11-12PIN <=> J41-29PIN
J11-13PIN <=> J41-28PIN
J11-14PIN <=> J41-27PIN
J11-15PIN <=> J41-26PIN
J11-16PIN <=> J41-25PIN
Go to step [12]
Replace
