Troubleshooting. Toner Cartridge and Drum Unit Problems
Replaced the toner cartridge with a new one but still seeing error message prompting toner cartridge replacement.
User Check
- Check that a new (not used) toner cartridge is set.
| Step | Cause | Remedy |
|---|---|---|
| 1 | Connection failure of the motor encoder PCB flat cable | Reconnect the motor encoder PCB flat cable. |
| 2 | Connection failure of the new toner sensor PCB harness | Reconnect the new toner sensor PCB harness. |
| 3 | Motor encoder PCB failure | Replace the motor encoder PCB ASSY. |
| 4 | New toner sensor failure | Replace the new toner sensor PCB ASSY. |
| 5 | Main PCB failure | Replace the main PCB ASSY. |
Toner cartridge cannot be detected
User Check
- Set the toner cartridge correctly.
| Step | Cause | Remedy |
|---|---|---|
| 1 | Connection failure of the motor encoder PCB flat cable | Reconnect the motor encoder PCB flat cable. |
| 2 | Connection failure of the new toner sensor PCB harness | Reconnect the new toner sensor PCB harness. |
| 3 | Motor encoder PCB failure | Replace the motor encoder PCB ASSY. |
| 4 | New toner sensor failure | Replace the new toner sensor PCB ASSY. |
| 5 | Main PCB failure | Replace the main PCB ASSY. |
Failed to detect toner cartridge
| Step | Cause | Remedy |
|---|---|---|
| 1 | The power switch was turned OFF or the top cover was opened while a new toner cartridge was being detected. | Reattach the new toner actuator. |
| 2 | New toner sensor PCB failure | Replace the new toner sensor PCB ASSY. |
| 3 | Main PCB failure | Replace the main PCB ASSY. |
Drum error
User Check
- Clean the corona wire of the drum unit.
- Replace the drum unit with a new one, and reset the drum counter.
| Step | Cause | Remedy |
|---|---|---|
| 1 | Dirt on electrodes of the drum unit and those of the machine | Clean the electrodes of the drum unit and those of the machine. (Refer to Fig. 1-7 and Fig. 1-8.) |
| 2 | Connection failure of the high voltage PCB harness | Reconnect the high voltage PCB harness. |
| 3 | High voltage power supply PCB failure | Replace the high voltage power supply PCB ASSY. |
| 4 | Main PCB failure | Replace the main PCB ASSY. |
Drum unit cannot be detected.
User Check
- Set the drum unit correctly.
| Step | Cause | Remedy |
|---|---|---|
| 1 | Dirt on electrodes of the drum unit and those of the machine | Clean the electrodes of the drum unit and those of the machine. (Refer to Fig. 1-7 and Fig. 1-8.) |
| 2 | Connection failure of the high voltage PCB harness | Reconnect the high voltage PCB harness. |
| 3 | High voltage power supply PCB failure | Replace the high voltage power supply PCB ASSY. |
| 4 | Main PCB failure | Replace the main PCB ASSY. |
Replace drum unit (replaced the drum unit with a new one but still seeing LED display prompting toner cartridge replacement)
User Check
- Replace the drum unit with a new one, and reset the drum counter.
| Step | Cause | Remedy |
|---|---|---|
| 1 | Main PCB failure | PCB ASSY. |
