Troubleshooting. Service Call Conditions. Summary
The ‘SC Table’ section shows the SC codes for controller errors and other errors. The latter (not controller errors) are put into four types. The type is determined by their reset procedures. The table shows the classification of the SC codes.
| Key | Definition | Reset Procedure | |
|---|---|---|---|
| Controller errors | CTL | The error has occurred in the controller. | See "Troubleshooting Procedure" in the table. |
| Other errors | A | The error involves the fusing unit. The machine operation is disabled. The user cannot reset the error. | Turn the main switch off and on. Reset the SC (set SP5-810-1). Turn the main switch off and on. |
| B | The error involves one or some specific units. The machine operates as usual, excluding the related units. | Turn the operation switch off and on. | |
| C | The error is logged. The SC-code history is updated. The machine operates as usual. | The SC will not show. Only the SC history is updated. | |
| D | The machine operation is disabled. You can reset the machine by turning the operation switch or main switch off and on. If the error occurs again, the same SC code is displayed. | Turn the operation switch or main power switch off and on. |
After you turn the main power switch off, wait for one second or more before you turn the main power switch on (SC 672). All SCs are logged. The print log data (SP5-990-004) in SP mode can check the latest 10 SC codes detected and total counters when the SC code is detected.
Note:
- If the problem concerns electrical circuit boards, first disconnect then reconnect the connectors before you replace the PCBs.
