In the usual work, before the customer uses UV flatbed printing, because the UV flatbed printer nozzle is too precise, for customers who are not particularly professional, there will be some faulty methods in the maintenance of the nozzle. If the maintenance operation of the nozzle is not proper, it is very likely that the nozzle will be directly damaged, which may result in more severe consequences. The following summarizes some of the faulty methods for the maintenance of sprinklers. I hope that customers will prevent these common faults during normal maintenance operations, so that the service life of the sprinklers can be effectively extended.
1. Use a high-pressure air gun to clean the nozzle vigorously when the nozzle is slightly blocked. This method is very inappropriate and will cause harm to the nozzle. If the spray head is slightly clogged, it is recommended to use a vacuum cleaner to suck the dust out, and then perform all complete cleaning.
2. Use residual ink or cleaning fluid to replace different batches of ink and ink suppliers, etc. The residual ink will not only affect the color and quality of the printed pictures, but also cause harm to the printer nozzle. The severe ones may also directly form irresistible losses such as nozzle clogging.
3. If the power supply is not completely enclosed, install or disassemble the circuit of the printer at will. This faulty operation method will endanger the service life of various systems of UV flatbed printers, including nozzles.
4. When using external force to adjust the orientation of the nozzle, do not use brute force, whether it is replacing or fine-tuning the nozzle. One faced the danger of nozzle formation.
5. In the article of nozzle maintenance, we mentioned that the nozzle should be immersed in the cleaning liquid for 1 ~ 2 hours. Long-term immersion of the cleaning liquid is helpful to understand the stain, but if the spray head is immersed in the cleaning liquid for more than 2 days, it will show a negative effect. Normally, the longest time for us to soak the spray head should not exceed 30 hours.
6. Soak all the nozzles in the cleaning solution, this method is not desirable. Because there are many electronic components on the spray head, and most of the cleaning fluids have a certain degree of corrosiveness, it must be noted that when soaking, only the right part of the spray can be soaked, and perhaps the appropriate amount of cleaning fluid is directly introduced into the spray head for cleaning.
7. Clean the nozzle frequently. Frequent cleaning of the print head is also an unstable behavior. On the one hand, the ink is wasted, and on the other hand, the print head will also have a certain impact. The frequency of nozzle cleaning usually advocates complete cleaning once a month. In normal use, the “active cleaning†function in the software can be used.
8. Failure to maintain the circuit board and other internal systems in time when cleaning the nozzle is also a disadvantage of the nozzle's death. Prompt customers to remember to close the power supply when cleaning, and waterproof the circuit board and other bare electronic components.
9. The application environment is not good, the temperature is too high or too low, maybe too moist. The UV flatbed printer has certain requests for the operating environment. Although the environmental impact will not directly cause harm to the equipment, it will also add the burden of the UV flatbed printer operation invisible. It is recommended to operate according to the instructions provided by the manufacturer.
This is a promotion business travel suitcase for men, which is suitable for travelling. It is use the zipper to close the luggage.
