Nozzle protection fluid

Epson nozzle cleaning method If the printer is not used for a long time, the ink in the nozzle may dry partially, resulting in no printing or poor printing effect. Most of the time, small bubbles appear in the ink supply system, which can easily form an air barrier in the ink inlet hole of the ink channel, causing the ink supply to the nozzle to be interrupted. This causes white lines to appear during printing, and the nozzles should generally be cleaned in time. You should also pay attention to the method when cleaning the nozzle. For minor problems, cleaning them once can solve the problem. If not, it’s best to leave it for half a day before cleaning. Every time you clean the nozzle, you should print a nozzle test chart to see if it improves after just one cleaning or if it becomes whiter with more cleaning and causes more disconnections. There are also many processing methods, generally following this procedure and performing nozzle cleaning after confirming that there is enough ink. Print a check nozzle test page. If there is still a disconnection, repeat the nozzle cleaning as many times as possible. If it doesn't work, leave it for half a day, then print the nozzle test page, and clean it again. . If it still doesn't work, take out the ink cartridge and check. Is there any air leakage from the ink outlet of the ink cartridge? Is the ink outlet rubber ring deformed? Do you still have ink? Or replace the ink cartridge (or original ink cartridge) and repeat step 1 again.
. After confirming that there is no problem with the ink cartridge, you can use a syringe to fill the cleaning unit carriage seat with cleaning fluid, return the carriage to its position and soak the nozzle for about minutes. Pay attention to different cleaning solutions. Long-term soaking may damage the nozzle. Turn on the printer and check the print nozzle, or clean the print head ~ times. You can also leave it for a few hours before printing and testing.
. If the soaking fails to clean it completely, you can also use a syringe filled with nozzle cleaning fluid to cover the hose (a rubber valve core can be used), and gently pull on the ink inlet column of the nozzle. If it cannot pull out, it means there is something in the nozzle. Blocking.
