How to extend the service life of the digital printing machine nozzle?

1. Correct use method
Avoid frequent switching: Try to reduce the frequent switching of the digital printing machine. Each time the machine is turned on, the nozzle needs to be initialized and preheated, which will cause certain impact and wear on the nozzle. If you need to pause printing for a short time, you can set the printer to standby mode instead of turning off the power directly.
Avoid long-term continuous printing: Long-term continuous printing may cause excessive fatigue of the nozzle and affect its service life. After a period of continuous printing, it is recommended to pause printing appropriately to give the nozzle time to rest and cool down.
Use according to the operating procedures: Strictly follow the operation manual of the digital printing machine, including the correct start-up and shutdown sequence, nozzle installation and disassembly methods, and printing parameter settings. Avoid damage to the nozzle due to improper operation.
2. Regular maintenance and maintenance
Nozzle cleaning: Regular cleaning of the nozzle is the key to keeping the nozzle in good condition. The cleaning frequency should be determined according to the use of the nozzle and the printing quality. It is generally recommended to clean the nozzle at least once a week. When cleaning, you should use a special nozzle cleaning fluid and follow the correct cleaning method to avoid using too sharp or rough tools to damage the nozzle.
Nozzle moisturizing: When the nozzle is not in use, pay attention to keeping the nozzle moist to prevent the ink from drying and clogging the nozzle. You can use tools such as nozzle moisturizing caps or moisturizing boxes to seal the nozzles and add an appropriate amount of moisturizing liquid to the moisturizing device regularly.
Regular calibration: Calibrate the nozzle regularly to ensure the correct distance and angle between the nozzle and the print medium to ensure the print quality and the normal operation of the nozzle. The calibration frequency can be determined according to the use of the equipment and the print quality. It is generally recommended to calibrate the nozzle once a month.
Check the nozzle status: Regularly check the appearance and working status of the nozzle, including whether there is ink residue, dirt or damage on the nozzle surface, whether the nozzle is spraying ink normally, etc. If there is a problem with the nozzle, it should be handled in time to avoid further deterioration of the problem.
3. Choose the right ink and printing medium
Ink quality: Choose ink that is reliable and compatible with the nozzle. High-quality ink has good fluidity, stability and solubility, which can reduce the risk of nozzle clogging. At the same time, pay attention to the storage conditions of the ink to avoid contamination or deterioration of the ink.
Printing media quality: Choose printing media suitable for digital printing machines, such as paper, cloth, etc. Factors such as the surface flatness, water absorption and roughness of the printing media will affect the inkjet effect and service life of the nozzle. You should choose a printing medium with good quality, flat surface and moderate water absorption to reduce the friction and wear between the nozzle and the printing medium.
4. Maintain a good working environment
Temperature and humidity: Keep the temperature and humidity of the working environment of the digital printing machine stable to avoid the impact of too high or too low temperature, too high or too low humidity on the nozzle. Generally speaking, the temperature should be controlled between 18℃-25℃, and the humidity should be controlled between 40%-60%.
Clean environment: Keep the working environment clean to prevent dust, debris, etc. from entering the interior of the digital printing machine and causing pollution and damage to the nozzle. You can clean the working environment regularly, and use a vacuum cleaner or a clean damp cloth to wipe the surface and surrounding area of ​​the equipment.
Good ventilation: Ensure that the working environment is well ventilated to prevent harmful gases generated by ink volatilization from accumulating indoors and causing harm to operators and equipment. You can install ventilation equipment or keep windows open to ensure indoor air circulation.
