When it comes to the maintenance of UV inkjet printers, everyone should know some of them, but they may not be too deep, so some maintenance methods are ignored, which leads to no good results, and in this case,weiqian The company has sorted out those maintenance methods that are easily overlooked .
Quickly “pick up” these easily overlooked maintenance methods for UV inkjet printers
1. After turning on the machine, start the negative pressure first, then open the valve in front of the mouth, close the valve in front of the mouth before shutting down, and then turn off the negative pressure to prevent ink leakage.
2. After turning on the machine, squeeze the ink first, then clean the print head to draw the line. If any defect is found, you need to squeeze the ink again, and wipe the print head with the provided dust-free cloth until the line is normal before it can be used normally.
3. Under various circumstances, do not directly touch the nozzle with your hands or other things. During the actual inkjet process, pay attention to check that the items cannot be directly scratched on the nozzle to prevent damage.
4. The nozzle should be wiped with a specially provided dust-free and soft cloth, wiped in one direction, and it is forbidden to wipe back and forth.
5. It is necessary to raise the nozzle when squeezing ink or wiping the nozzle, but be careful to turn off the curing light. And in the production process, it is necessary to prevent the afterglow of the UV lamp from irradiating the nozzle.
6. After each use, you need to re-squeeze the ink. After wiping the nozzle with a dust-free cloth, make sure that the nozzle is fine, cover the nozzle cover, and then shut down.
7. If the printing process is interrupted, it is not necessary to shut down the machine. It is necessary to wipe the nozzle, and then cover the nozzle with the nozzle cover. But the next time you print, you need to pull the line to confirm that the nozzle is free of defects before printing.
8. If it is not in use for more than 3 days, after squeezing the ink, wipe the nozzle clean, and after cleaning the nozzle line, after making sure it is normal, cover the nozzle cover, and then seal the nozzle with an opaque black plastic wrap.
9. When not in use for more than half a month, drain the ink in the ink path, then wipe the nozzle, cover the nozzle cover, and wrap the nozzle with an opaque black fresh-keeping bag.
10. The filter of the nozzle assembly should be replaced every 3 months. After the replacement, the air bubbles in the ink tube of the nozzle need to be discharged to prevent negative pressure and printing effect from being affected.
11. The shelf life of unsealed ink is 2 months. If the ink is not used up after the expiration date, pour it out and use it again, and re-exhaust the air bubbles to prevent the negative pressure and printing effect from being affected.
