CHAPTER 7 TROUBLESHOOTING
E805
While the fan is rotating, fan lock state is detected for 10 sec or more con-
tinuously.
Main cause
The fan is faulty. The DC controller PCB is faulty. The image processor
PCB is faulty.
Action
1. Foreign matter
Is there any foreign matter that hinders the rotation of the heat discharge
fan?
YES: Remove the foreign matter.
2. Wiring, Connection
Are the wiring and connection (connectors) of the fan normal?
NO:
Correct them.
3. Fan
Try replacing the fan. Is the problem corrected?
YES: End.
4. DC controller PCB/Image processors PCB
Try replacing the DC controller PCB. Is the problem corrected?
YES: End.
NO:
Replace the image processor PCB.
E810
The case that the toner bottle is detected, but not the cartridge.
Main cause
The DC controller PCB is faulty. The cartridge is faulty.
Action
1. High-voltage contact (between machine and the developing unit)
Is the high-voltage spring used to supply high voltage to the developing
unit soild?
YES: Clean it.
2. High-voltage contact (between high-voltage spring and DC controller
PCB; J207)
Is the connection between the high-voltage spring and the DC controller
PCB(J207) normal?
NO:
Correct the connection. If the problem cannot be corrected, replace
the faulty part.
3. Developing unit, DC controller PCB
Replace the developing unit. Is the problem corrected?
YES: End.
NO:
Replace the DC controller PCB.
