The engineers of inkjet printer manufacturers are often asked by many users, why do cij printers need maintenance? How to maintain the printer? I believe that many users will be concerned about such issues. So today’s cij printer manufacturer’s project is here to explain the maintenance of the nozzle of the cij printer: everyone knows that the nozzle is one of the important parts of the cij printer, and the nozzle focuses on maintenance and maintenance, which is directly determined by the maintenance. The use effect and life of the nozzle, how to make your equipment bring greater profits. Extending the working life of the nozzle is one of the means to reduce costs. 1. After starting the machine, start the negative pressure first, then open the front valve of the mouth, close the front valve of the mouth before shutting down, and then close the negative pressure to prevent ink leakage.

2. After turning on the machine, first squeeze the ink, then clean the print head, check the status of the print head (line drawing), if line defects are found, you need to re-squeeze the ink, wipe the print head with the provided dust-free cloth, until the line drawing effect is normal. use.

3. Under no circumstances should you directly touch the print head with your hands or other objects. In the actual inkjet process, please pay attention to the inspection items not to directly scratch the print head to prevent damage. 4. The nozzle should be wiped with a soft and clean dust-free cloth specially provided. Wipe in a single direction when wiping, and it is forbidden to wipe back and forth. 5. When squeezing ink or wiping the nozzle, you need to raise the nozzle, but pay attention to turn off the curing lamp. And in the production process, it is necessary to prevent the residual light 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, close the nozzle cover, and then shut down. 7. If the printing process is interrupted, the printer does not need to be shut down, but when printing is performed next time, you need to draw a line to confirm that the nozzle is free of defects before printing. If you stop printing for more than 3 hours, you need to wipe the nozzle, and then cover the nozzle with the nozzle cover. 8. If you do not use it for more than 3 days, you need to wipe the print head by squeezing ink every three days, and after cleaning the print head to draw the lines, cover the print head cover, and then use opaque plastic wrap to seal and wrap the print head. 9. If you do not use it for more than half a month, you must drain the ink in the ink path, then wipe the nozzle clean, cover the nozzle cap, and wrap the nozzle with opaque plastic wrap. 10. The filter of the nozzle assembly should be replaced every 3 months. After the replacement is completed, the air bubbles in the nozzle ink tube need to be discharged to avoid affecting the negative pressure and the printing effect. 11. The shelf life of the ink after opening is 2 months. The unused ink must be poured out after the expiration date. The ink tank must be refilled with new ink for use, and air bubbles must be re-vented to avoid negative pressure and printing effects.
