PIJ UV Digital Nozzles Repairing Service Piezoelectric nozzle is a high-precision inkjet device commonly used in industrial printing, 3D printing, or high-end printers. Due to its working principle relying on piezoelectric crystal deformation to drive ink ejection, clogging or performance degradation of the nozzle will directly affect the printing quality. The following is a maintenance and cleaning guide for piezoelectric nozzles, covering common problems and solutions. Our company specializes in cleaning various piezoelectric nozzles with high cost-effectiveness. Firstly, we will analysis the common problems and reasons of the nozzles 1.1 Spray hole blockage -Dry ink residue (long-term disuse or ink evaporation) -Ink precipitation (pigment ink is more prone to occur) -Impurities mixed in (poor ink quality or environmental dust) 1.2. Nozzle deviation/breakage -Fatigue or damage of piezoelectric crystals -Drive circuit malfunction -Abnormal surface tension of ink 1.3. Insufficient spraying force

-Abnormal voltage drive (calibration required) -Ink viscosity too high or temperature too low Secondly, we will cleaning and maintenance following step by step 1. Basic cleaning (mild blockage) Tool preparation: dust-free cloth, specialized cleaning solution (such as nozzle cleaner or diluted isopropanol), syringe, distilled water. Operating Procedure 1. Surface wiping: After power off, gently wipe the surface of the nozzle with a dust-free cloth dipped in cleaning solution to remove external stains. 2. Negative pressure suction: Connect the syringe sleeve hose to the nozzle inlet, slowly suction...
