1. The key to cleaning the printhead is "gentleness" and "dedicated cleaning solution." Moisten a lint-free cloth with printhead cleaning fluid (or UV cleaning fluid), lay it flat, and gently wipe the printhead surface in one direction to remove residual ink. Never scrape vigorously. After cleaning, be sure to let it air dry for 4-5 days to ensure it is completely dry before reinstalling it in the printer.
2. Daily cleaning: Wipe the printhead surface and surrounding area weekly with a cotton swab or non-woven cloth with a rinse solution in one direction to keep it clean. When not in use, return the printhead to the "humidification seat" to prevent ink from hardening.
3. Deep cleaning: If the printhead is severely clogged, briefly soak it in warm water to soften the dried ink, then blot dry with a lint-free cloth. In an emergency, a hairdryer at around 40℃ can be used to dry the printhead circuitry, but this should be done with caution.
4. Precautions: Always use purified water or a dedicated cleaning solution. Impurities in tap water can clog the printhead. Avoid getting water into the printhead circuit board during cleaning. Use genuine ink; mixing inks from different brands is strictly prohibited.
