Here are some products that can prevent printer nozzles from clogging:

1. Original ink/high-quality compatible ink:

• Original ink: The original ink produced by the printer manufacturer itself has been strictly tested and adapted, and is most compatible with the printer's nozzles, which can minimize the risk of nozzle clogging. For example, the original inks of brands such as HP, Canon, and Epson are perfectly compatible with their own printer nozzles in terms of ink particle size, pH, viscosity, etc., which can ensure the smoothness and stability of printing. Although the price of original ink is relatively high, it is a worthwhile investment for users who pursue print quality and hope to reduce nozzle failures.

• High-quality compatible ink: If cost factors are considered, some high-quality compatible inks are also a good choice. These compatible inks will be developed and produced in accordance with the standards of original inks during the production process, and the performance is as close to the original ink as possible. For example, some well-known third-party ink brands have a certain guarantee on the quality of the ink they produce, and have undergone a lot of testing and verification, and can be applied to a variety of printer models. But when choosing compatible ink, be sure to choose a brand with good reputation and reliable quality to avoid using inferior inks that cause nozzle clogging.

2. Nozzle cleaning fluid:

• Special cleaning fluid: The cleaning fluid specially used for cleaning the printer nozzle is an important product for preventing and solving the problem of nozzle blockage. This cleaning fluid can effectively dissolve the ink residue, dried ink blocks and other impurities in the nozzle to keep the nozzle unobstructed. When using, you need to pour the cleaning fluid into the printer's ink cartridge or nozzle cleaning device, and then follow the printer's cleaning procedure. The cleaning fluid should not be used too frequently. It is generally recommended to use it when the printer shows signs of reduced print quality and nozzle blockage.

• Ultrasonic cleaning fluid: For some nozzles with severe blockage, ultrasonic cleaning fluid can be used for cleaning. Soak the nozzle in ultrasonic cleaning fluid, and use the vibration of ultrasonic waves to make the tiny bubbles in the cleaning fluid continuously impact the nozzle surface to completely remove the blockage. However, this method requires the use of special ultrasonic cleaning equipment, and the operation is relatively complicated. It is recommended to be carried out under the guidance of professionals.

3. Print head protective cover/sealing plug:

• Protective cover: The print head protective cover can be covered on the print head when the printer is not in use to prevent dust, debris, etc. from entering the nozzle, thereby reducing the possibility of nozzle clogging. The material of the protective cover is generally plastic or rubber, with good sealing and dustproof properties. Different models of printers may require protective covers of different sizes, so you need to choose a product that matches your printer when purchasing.

• Sealing plug: The sealing plug is mainly used to plug the ink outlet of the printer cartridge to prevent the ink from drying and leaking when it is not used for a long time. The sealing plug is usually made of rubber or silicone and has good elasticity and sealing. Before the printer is idle for a long time, install the sealing plug on the ink outlet of the ink cartridge to effectively protect the ink cartridge and nozzle.

4. Accessories of continuous ink supply system/ink tank printer:

• Filter of continuous ink supply system: The continuous ink supply system is a device that continuously supplies ink, which can reduce printing costs. The filter in the continuous ink supply system can filter impurities in the ink to prevent impurities from entering the nozzle, thereby preventing the nozzle from clogging. The filter needs to be replaced regularly to ensure its filtering effect.

• Anti-drying ink components of ink tank printers: Due to the large ink capacity and long use time of ink tank printers, ink tank printers are prone to ink drying. Some ink tank printers are equipped with anti-drying ink components, such as some ink tank printers of Epson. Their micro-piezoelectric print heads are equipped with protective covers, which can automatically collect bubbles to prevent clogging. At the same time, specially selected polymer material ink tubes are used to isolate the air with high density to prevent ink drying.

5. Paper: Choosing paper with good quality, smooth surface and not easy to shed powder can also prevent nozzle clogging. Because poor quality paper may shed powder, these powders will enter the inside of the printer, contaminate the nozzle and cause clogging. For example, some brands of professional printing paper have uniform paper fibers and specially treated surfaces, which not only have good printing effects, but also cause less damage to the printer nozzle.
