5. Maintenance

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Printer shoots out blank labels after printing. | Incorrect label type selected (e.g., "Gap Label" for continuous paper). | When printing with continuous labels, ensure you select "Continuous Label" mode in the app. If "Gap Label" is selected, the printer will automatically retrieve a blank gap. |
| Cannot connect to the printer via Bluetooth. | Bluetooth not enabled, incorrect connection method, or GPS permission missing. | 1. Ensure Bluetooth is enabled on your phone. 2. Connect Bluetooth only within the 'Marklife' app, not through your phone's system settings. 3. If the printer cannot be found, ensure "GPS" (location services) is turned on for the app, as it may be required for Bluetooth scanning on some Android devices. |
| Printer does not work after connecting to Bluetooth. | Connection not properly established within the app. | Verify that the printer's indicator light is blue and "link" is displayed in the upper right corner of the app's printing interface. If not, disconnect and reconnect within the app. |
| Poor print quality. | Dirty print head or low battery. | Clean the print head as described in the Maintenance section. Ensure the device is sufficiently charged. |
