Now let's take a look at how it cleans the print head of the printer, taking the print head of Epson ex3 as an example.
I deliberately left the printer idle for a week first, without turning it on or checking the print nozzle. After a week, I directly turned it on and tested the print nozzle. The results are as shown in the following figure:
It can be seen that the nozzles are basically completely blocked. Only a few nozzles can still print. I used the automatic cleaning function of the printer and cleaned it five times in a row, but still had no effect. Next, we will start the manual cleaning.
Prepare an ultrasonic cleaner
Inject about 3MM of Baofeng special cleaning solution into the cleaning machine. Pure water can also be used as a substitute, but the effect will be much worse. Place the removed nozzle into the ultrasonic cleaner until the cleaning solution just covers the print head, with the liquid level approximately 0.5cm above the print head.
One more time. Check the blockage with a simple cleaner:
If the ink sprayed out has bifurcations or obvious intervals, it indicates that the nozzle has not been completely cleaned and needs to be further cleaned or soaked. font-family:Arial, Verdana, sans-serif;" >
Repeat this process repeatedly!
After the nozzle is completely cleared, remove the print head, dry the excess cleaning solution or carefully dry the print head with a hair dryer. Please note that you must wait until the print head is completely dry before installing it into the printer; otherwise, it is very likely to burn out the print head!
After installation in the printer, turn it on, clean it (the purpose is to wash away the excess cleaning liquid in the nozzle and ensure that the ink fully fills the print head), and test the print nozzle until a complete test line is printed.
Of course, the functions of ultrasonic cleaners are far more than these. There are still other aspects waiting for us to explore.
