Troubleshooting Self Diagnostic
7 - 3 Self Diagnostic
If the part causing the problem was not supplied, use the unit including the part for replacement.
Caution
Before attempting to check the fuser unit and the low voltage power supply PWB, be sure to turn the power switch off and unplug the machine from power.
Even if the power switch of the main unit is turned off and the power cord is unplugged, the electric charge may remain in the capacitors on the low voltage PWB, so that please be careful not to touch the mounted parts to protect you from electric shock.

Troubleshooting Self Diagnostic
C0070: FAX PWB incompatible detection error
Abnormal detection of FAX control PWB incompatibility in the initial communication with the FAX control PWB, any normal communication command is not transmitted.
| Step | Check description | Assumed cause | Measures |
|---|---|---|---|
| 1 | Checking the FAX PWB | The incompatible FAX PWB is installed. | Install the FAX PWB for the applicable model. |
| 2 | Firmware upgrade | The FAX firmware is faulty. | Reinstall the FAX firmware. |
| 3 | Replacing the main PWB | The main PWB is faulty. | Replace the main PWB. |
C0100: Backup memory device error
An abnormal status is output from the flash memory.
| Step | Check description | Assumed cause | Measures |
|---|---|---|---|
| 1 | Resetting the main power | The flash memory does not operate properly. | Turn off the power switch and unplug the power plug. After 5s passes, reconnect the power plug and turn on the power switch. |
| 2 | Checking the main PWB | The connector or the FFC is not connected properly. Or, the wire, FFC, the PWB is faulty. | Clean the terminal of the connectors on the main PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace them. If not resolved, replace the main PWB. |
C0120: MAC address data error
The MAC address data is incorrect.
| Step | Check description | Assumed cause | Measures |
|---|---|---|---|
| 1 | Resetting the main power | The flash memory does not operate properly. | Turn off the power switch and unplug the power plug. After 5s passes, reconnect the power plug and turn on the power switch. |
| 2 | Checking the MAC address | The MAC address is incorrect. | Replace the main PWB when the MAC address is not indicated on the network status page. |
C0130: Backup memory reading/writing error
The reading or writing into the flash memory is unavailable.
| Step | Check description | Assumed cause | Measures |
|---|---|---|---|
| 1 | Resetting the main power | The flash memory does not operate properly. | Turn off the power switch and unplug the power plug. After 5s passes, reconnect the power plug and turn on the power switch. |
| 2 | Checking the main PWB | The connector or the FFC is not connected properly. Or, the wire, FFC, the PWB is faulty. | Clean the terminal of the connectors on the main PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace them. If not resolved, replace the main PWB. |
C0140: Backup memory data error
