4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your NEJE 5 PLUS.
- Lens Care: The latest lens design includes a high-temperature window lens to protect against water and smoke damage. Ensure the lens is kept clean. Damage due to lack of maintenance is not covered under warranty.
- Air Assist System: For optimal cutting performance, especially with thicker materials, use an air pump providing 0.5-1.5MPa clean air. The needle-type air nozzle supports oily and water-containing air sources, while the sealed air nozzle requires clean air only.
- General Cleaning: Keep the machine free from dust and debris. The frame material is designed for easy maintenance.
5. Troubleshooting
Here are some common issues and their solutions:
- Unexpected Stops: The machine features MEMS vibration protection. If the engraving process is accidentally touched, it will automatically stop working. Check for any physical interference.
- Emergency Shutdown: The door control function provides emergency suspension. Ensure all safety mechanisms are properly engaged.
- Overheating: The laser module has a built-in intelligent drive with temperature feedback and control. The safe operating temperature range is below 60β. If the module feels excessively hot, allow it to cool down. The fan intelligently adjusts heat dissipation.
- Power Issues: The device has surge protection. Ensure the power input is DC 12V 4A or 5A. Incorrect voltage input can cause damage and void the warranty.

8. User Tips
Maximize your experience with these helpful tips:
- Optimize Cutting for Plywood: For 8mm plywood, the A40640 module can achieve clean cuts in a single pass when air assist is correctly applied (0.6-1.5MPa).
- Secure Materials: Always ensure your material is properly secured to the working surface to prevent any movement during engraving or cutting, which can affect speed and precision.
- Metal Engraving: While the NEJE 5 PLUS can engrave stainless steel directly in grayscale, for other metals, surface preparation (e.g., coating) might be necessary for optimal results, as direct engraving on some metals may not be possible.
- Software Updates: Regularly check for OTA software updates via the NEJE Win software or NEJE APP to benefit from the latest features and performance optimizations.
