FIP-2 Magenta Toner Cartridge Detached (Magenta Toner Cartridge Missing)
Step
Initial check
Check the following for damage.
Cartridge condition
1 SW TCRU ASSY (M) condition
SW TCRU ASSY (M) actuator condition
SW TCRU ASSY SW TCRU ASSY (M) connector
condition
Check SW TCRU ASSY
Using the diagnostic tool, check by Diagnostic Input Test.
2
Does SW TCRU ASSY (Magenta Cartridge Toner Bottle
Sensor) function normally?
Check PWBA HNB DRV for signal
3
Is P/J51-13PIN <=> P/J51-14PIN 0VDC?
Check SW TCRU ASSY(M) for signal
4
Is P/J432-2PIN <=> P/J432-1PIN 0VDC?
Check SW TCRU ASSY (M) for continuity
5 P432-2PIN <=> P432-1PIN of SW TCRU ASSY (M) check
continuous?
Check HARNESS ASSY TNR for continuity
6
J51 <=> J432 check continuous?
Check PWBA HNB DRV for signal
7
Is P/J42-5PIN <=> P/J42-14PIN 0VDC?
Check PWBA HNB MCU for signal
8 Is P/J11-26PIN <=> P/J11-17PIN of HNB MCU WITHMCU
PWB 0VDC?
Check HARNESS ASSY DRV2 for continuity
9
J12 <=> J42 check continuous?
1-38
