9. User Tips
Based on general usage and product characteristics, here are some tips for optimizing your experience:
- For best results on curved surfaces, practice printing on scrap materials first to get a feel for the required movement and pressure.
- When printing on non-absorbent surfaces like metal or plastic, ensure the surface is completely free of grease or dust for optimal ink adhesion.
- If using different ink types (water-based vs. solvent), ensure you use the correct cartridge for your application and clean the nozzle thoroughly when switching.
- Always keep the nozzle protection cover on when the printer is not in active use to prevent the ink from drying out.
