FIP-2 Magenta Toner Cartridge Detached (Magenta Toner Cartridge Missing)Step Check Yes No
1
Initial check
Check the following for damage.
Cartridge condition
SW TCRU ASSY (M) condition
SW TCRU ASSY (M) actuator condition
SW TCRU ASSY SW TCRU ASSY (M) 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 (Magenta Cartridge Toner Bottle
Sensor) function normally?
Replace PWBA
HNB MCU Go to step [3]
3Check PWBA HNB DRV for signal
Is P/J51-13PIN <=> P/J51-14PIN 0VDC? Go to step [7] Go to step [4]
4Check SW TCRU ASSY(M) for signal
Is P/J432-2PIN <=> P/J432-1PIN 0VDC? Go to step [6] Go to step [5]
5
Check SW TCRU ASSY (M) for continuity
P432-2PIN <=> P432-1PIN of SW TCRU ASSY (M) check
continuous?
Go to step [6] Replace SW
TCRU ASSY (M)
6Check HARNESS ASSY TNR for continuity
J51 <=> J432 check continuous? Go to step [7]
Replace
HARNESS ASSY
TNR
7Check PWBA HNB DRV for signal
Is P/J42-5PIN <=> P/J42-14PIN 0VDC? Go to step [8] Replace PWB
HNB DRV
8
Check PWBA HNB MCU for signal
Is P/J11-26PIN <=> P/J11-17PIN of HNB MCU WITHMCU
PWB 0VDC?
Replace PWBA
HNB MCU Go to step [9]
9Check HARNESS ASSY DRV2 for continuity
J12 <=> J42 check continuous?
Replace PWBA
HNB MCU
Replace
HARNESS ASSY
