Step Check
Yes No
1
Initial check
Check the following for damage.
Cartridge condition
SW TCRU ASSY (C) condition
SW TCRU ASSY (C) actuator condition
SW TCRU ASSY SW TCRU ASSY (C) connector
condition
Replace the parts
concerned
With tool
Go to step [2]
Without tool
Go to step [3]
2
Check SW TCRU ASSY
Using the diagnostic tool, check by Diagnostic Input Test.
Does SW TCRU ASSY (Cyan Cartridge Toner Bottle
Sensor) function normally?
Replace PWBA
HNB MCU
Go to step [3]
3
Check PWBA HNB DRV for signal
Is P/J51-29PIN <=> P/J51-30PIN 0VDC?
Go to step [7] Go to step [4]
4
Check SW TCRU ASSY (C) for signal
Is P/J433-2PIN <=> P/J433-1PIN 0VDC?
Go to step [6] Go to step [5]
5
Check SW TCRU ASSY (C) for continuity
P433-2PIN <=> P433-1PIN of SW TCRU ASSY (C) check
continuous?
Go to step [6]
Replace SW
TCRU ASSY (C)
6
Check HARNESS ASSY TNR for continuity
J51 <=> J433 check continuous?
Go to step [7]
Replace
HARNESS ASSY
TNR
7
Check PWBA HNB DRV for signal
Is P/J42-6PIN <=> P/J42-14PIN 0VDC?
Go to step [8]
Replace PWB
HNB DRV
8
Check PWBA HNB MCU for signal
Is P/J12-25PIN <=> P/J12-17PIN of PWBA HNB MCU PWB
0VDC?
Replace PWBA
HNB MCU
Go to step [9]
9
Check HARNESS ASSY DRV2 for continuity
J12 <=> J42 check continuous?
Replace PWBA
HNB MCU
