Troubleshooting
If you encounter any issues with your Ninestar G&G Thermal Printer, please refer to the following common troubleshooting steps:
- Printer not connecting via Bluetooth: Ensure the printer is powered on and within range. Check your smartphone's Bluetooth settings to confirm it's enabled and visible. Try restarting both the printer and your smartphone.
- No print output or blank prints: Verify that the thermal paper is loaded correctly with the printing side facing outwards. Ensure there is enough paper in the roll. The printer uses thermal technology, so no ink is required.
- Poor print quality: Check if the thermal paper is old or exposed to heat/light, which can degrade its quality. Ensure the printer's print head is clean (refer to maintenance section for cleaning instructions if available in the app manual).
- App issues: Make sure the "Print-Label" app is updated to the latest version. If the app crashes or freezes, try force-closing and reopening it. Reinstalling the app might also resolve persistent issues.
- Battery not charging: Ensure you are using a compatible USB AC adapter (DC5V 1A) and the provided USB Type-C cable. Check the charging port for any debris.
