Description: The case that the toner bottle is detected, but not the cartridge.
Causes: - The DC controller PCB is faulty. The cartridge is faulty.
Remedy: 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.
