4. Maintenance
4.1 Cleaning the Print Head and Rollers
Regular cleaning helps maintain print quality and extends the life of your printer. Clean the print head and rubber rollers if you notice:
- Unclear printing
- Loud noise during paper feeding or paper return
Steps for cleaning:
- Power off the printer.
- Open the paper bin cover and locate the print head (a dark strip) and rubber rollers.
- If the printer was just used, wait for the print head to cool completely.
- Gently wipe the print head and rubber rollers with a cotton swab lightly moistened with rubbing alcohol to remove any residue or debris.
- Allow the alcohol to completely evaporate before closing the cover and powering on the printer.
4.2 Battery Care
- Charge the printer for at least 30 minutes if it does not power on.
- Avoid exposing the printer to extreme temperatures (below 0°C/32°F or above 50°C/122°F) to preserve battery life.
5. Troubleshooting
5.1 Common Issues and Solutions
- Printer printing blank labels:
This usually indicates the label paper is laid reversely. Ensure the label side is facing down when loading the roll.
- Printer continuously feeds labels:
Check for residue or debris on the sensors or print head. Clean the paper bin cover and print head as described in the Maintenance section. Also, ensure you are using genuine label paper for best results.
- Printout looks gray or faded:
This can happen if the label roll is heat sensitive or if the print head needs cleaning. Try cleaning the print head with rubbing alcohol.
- Printer skips labels:
Check if the label size and template match in the app. Reinstall the label roll, ensuring it's correctly positioned. Press the power button five times to print a self-test page, or double-click to retract label paper.
- Printer does not power on:
Charge the device for at least 30 minutes. If the issue persists, contact customer support.
- Bluetooth connection issues:
Ensure Bluetooth is enabled on your device and the printer is within range. Restart both the printer and your mobile device. Re-pair the printer through the NIIMBOT app.
