In digital inkjet printing, static electricity can have an impact on the print head, circuit board, ink, printing media, etc. Specifically, these phenomena will occur:
Print head: Static electricity can cause the accumulation of dust and other small impurities inside the print head, which can clog the nozzle, affect printing quality, and even damage the nozzle.
Circuit board: Static electricity may damage sensitive circuit components, leading to equipment failure or performance degradation.
Ink: Static electricity may cause interference during the spraying process, resulting in uneven ink atomization and the formation of ink flying, which not only affects printing quality but may also contaminate the interior of the printer.
Printing media: Static electricity may also cause adhesion of printing media (such as paper, fabric, etc.) during transmission, leading to printing misalignment or paper jamming.
Finished product quality: Static electricity attracts dust and other particles, making the printed product surface unclean and reducing product quality.
Equipment stop working: Strong static electricity may cause the equipment to temporarily stop working, affecting production progress.
Solution to static electricity
Using an electrostatic tester: By using the FMX-004 electrostatic tester or online electrostatic monitor, you can accurately understand the source of static electricity generated on the production line and the specific location where static electricity needs to be eliminated.
Install anti-static equipment: Some high-end digital inkjet printers will be equipped with specialized anti-static equipment, such as ion fans or anti-static bars, which can effectively neutralize static electricity and reduce its impact on printer components. The Yifang (Osno) UV tablet series is equipped with an electrostatic rod configuration, which can effectively target materials that are easily charged and extend the service life of components.
Using anti-static media: Choosing a printing medium that has undergone anti-static treatment, such as anti-static paper or fabric, can reduce the impact of static electricity on the printing medium and improve printing quality.
Control environmental humidity: Maintaining appropriate humidity can reduce the generation of static electricity. Usually, controlling environmental humidity within the range of 50% to 70% can significantly reduce static electricity issues.
Grounding wire and alcohol wiping: Ensure that the printer has a good grounding, use alcohol to wipe the surface of the material to remove static electricity.
Regular cleaning and maintenance: Regularly cleaning the inside of the printer, especially the nozzle and ink system, can prevent the accumulation of dust and other impurities, and reduce the impact of static electricity on the nozzle.
Please note that the above measures should be adjusted and optimized based on the specific printer model and usage environment. Please feel free to consult us for more details.
In addition, after understanding the above content, it is necessary to strengthen employee training and provide appropriate training to operators to understand the hazards and preventive measures of static electricity, ensuring that correct operation methods can be adopted in daily work to reduce the generation of static electricity.
