At present, inkjet printer technology is constantly making new breakthroughs, the performance of inkjet printer equipment is increasing, and the fields it is involved in are becoming more and more extensive. However, in printing operations, there is always a “potential hidden danger” that is looming, interfering with the printing quality and output effect from time to time, and even posing a potential risk to the life of the equipment itself. This is “static electricity”. Today, let’s discuss the impact of humidity on inkjet printer printing with Century Wind, analyze the reasons for its generation, and seek effective countermeasures.
Hazards of static electricity:
Printhead: Static electricity can cause dust and other tiny impurities to accumulate inside the nozzle. These impurities may cause the nozzle to be blocked, which in turn affects the clarity of printing. In severe cases, it may even cause nozzle wear or failure.
Ink: Static electricity may interfere with the ink during the output process, causing the ink droplets to deviate from the correct landing point, resulting in flying ink, spots, and blurring problems, which not only affect the printing quality and accuracy, but also may pollute the inside of the equipment.
Printing media: Static electricity may also cause the printing media (such as paper) to stick together during the conveying process, resulting in the offset of printed content or frequent paper jams.
Circuit boards: Static electricity may damage sensitive circuit components, causing equipment failure, stopping work or performance degradation.
Quality of finished products: Static electricity attracts dust and other particles, making the surface of printed products unclean and reducing product quality.
Solutions to static electricity:
Install anti-static equipment Some high-end inkjet printing equipment will be equipped with special anti-static equipment, such as static elimination rods, which use high-voltage electric fields or static eliminators to generate charges of opposite polarity, thereby neutralizing the static charge on charged objects and achieving the purpose of eliminating static electricity.
Use anti-static printing media Selecting anti-static treated printing media, such as anti-static paper, can reduce the impact of static electricity on printing media and improve printing quality.
Control environmental humidity Maintaining appropriate humidity can reduce the generation of static electricity. Under conditions of relative humidity of 35%~65%, static electricity can be reduced by up to 80%.
“Grounding wire” elimination method Carefully handle the grounding problem of the ground wire. It is best to use a whole wire for the ground wire without joints, and ensure good contact with the machine to avoid static electricity accumulation.
Regular cleaning and maintenance Regularly cleaning the inside of the inkjet printing equipment, especially the nozzle position, can prevent the accumulation of dust and other impurities and reduce the impact of static electricity on the nozzle.
The above measures should be adjusted and optimized according to the specific inkjet printer equipment model and usage environment. In addition, employee training should be strengthened to make them deeply understand the hazards and preventive measures of static electricity, and ensure that they can take correct operating methods to reduce the generation of static electricity in daily work.
