The continuous ink supply system is believed to be used by many users who purchase inkjet printers. The reason for purchasing a continuous ink supply system is nothing more than cheap ink, which can save costs. However, in actual use, because of the compatibility problem between the printer and the continuous ink supply system, after a period of use, continuous ink supply will "help" the printer plug. This is almost as long as the continuous ink supply system is used. Will appear. So, is there a way to use the continuous ink supply system freely, and it will not become unusable because of the plugging? The answer is yes. That is to know the cause of the failure of the plug correctly and clean it correctly. Generally, the reason for the failure can be roughly analyzed. However, not everyone knows the correct cleaning, especially after finding the cause of the fault, the fierce mentality has caused many users to get excited, and the impulse, the simple problem is complicated, but the previous achievements are abandoned. Therefore, here, focus on telling everyone how to clean the plug properly. The causes of inkjet printer head clogging can be divided into soft head plugs and hard head plugs. Most of them are large particles in the ink, which are stuck in the nozzle. It may also be that the printer has not been used for a long time, and the ink is dry in the nozzle. Or different inks are mixed with each other to produce a chemical reaction. Treatment of the soft plug of the nozzle: Soft plugging refers to a wire breakage caused by the increased viscosity of the ink on the nozzle due to various reasons. Sometimes it is only attached to the surface of the nozzle of the ink outlet, and it can be recovered after multiple cleanings with the original ink tank, but this method is more wasteful of ink. (1) Press the cleaning button to clean. As mentioned earlier, the cleaning process of each machine is not exactly the same, but generally has this function. Or use the print head cleaning function in the printer driver application tool to clean. The cleaning of the above two steps is generally not more than three times. The head is not serious, and it should be washed away within three times. If it can't be opened three times, it means that the head is blocked seriously. No matter how many times it is cleaned, it is not necessarily useful, and a lot of ink is wasted. (2) However, it should also be noted that due to the air resistance phenomenon between the ink cartridge (filled with sponge) and the print head, a small amount of irregular disconnection will occur. In this case, it is not necessary to repeatedly clean it. It can be completely normal. At this time, when observing the surface of the nozzle, we can see through the light on the nozzle surface that an ink hole is discharged (generally 6-color printers have 6 rows of nozzles), some places still have cleaning fluid, and some places are completely penetrated from the ink absorption Drip out. This shows that there is indeed a plugging problem in some parts of the nozzle. We can follow the above method again until the nozzles are all clear. Note: 1. The third method is to perform this operation after the print head is removed from the printer. If the print head has been unclogged with a needle barrel and a rubber tube, we will find that the cleaning fluid is always left on the surface of the nozzle. 2. The cleaning liquid has strong cleaning power. Generally, the nozzle can be cleaned within a few minutes. It is mostly used for the treatment of medium plugging, but it cannot be left in the nozzle for a long time. Treatment of hard plugs of sprinklers Hard plugs refer to plugs caused by chemical solidification or impurities in the sprinklers. It is difficult to eliminate this fault and must be handled manually. (1). First, remove the spray head, and operate according to the above method (3). There are still some colors in the print head which are not normal. At this time, we first find a container with a flat bottom surface, add a little pure water to the container, the pure water is limited to just cover the stainless steel edge of the print head. The soaking time generally ranges from 2 hours to one day. After soaking, use the above method (3) to operate. Generally, the nozzle can be dredged at the plugging point. For severe plugging, the above method can be used multiple times. (2) According to the above method, we will feel that the hard plug of the nozzle is too long, but for the precision parts such as the print head, safety is still the first. The ultrasonic cleaners on the market now do have a good effect. Before using the ultrasonic cleaner, proceed as described above. The main purpose is to make the crystals in the nozzle relatively soft and achieve better results. But there are still some problems to remind everyone here. During this time, the new inkjet printer launched by EPSON, because the nozzle structure may be made more elaborate, so after using the ultrasonic cleaner, you will find that the problem of over-washing becomes more serious. So be sure to pay attention before using the ultrasonic cleaner. (3) Ultrasonic cleaning machine, on the one hand, the good price is more expensive, on the other hand, the above method can solve more than 85% of the plug problem. By the way, there is another more practical method, which is to add a rubber tube with a needle barrel. After step by step according to the above method. This method is only used for some still stubborn nozzles. Use a needle bucket (5ml, 10ml, 20ml can be used) to add some purified water, leaving a certain space of air in the needle bucket. Put the rubber tube on the needle barrel and nozzle to absorb ink. Repeat the light push and light pumping, and observe the change of ink droplets. You can also add the cleansing liquid into 1: 2, 1: 3 dilution and then add purified water to perform this operation. For general users who have relatively little knowledge of printers, removing the print head will invisibly increase the risk. Especially for some newer EPSON machines, it is more difficult to disassemble. Is there a better way to solve the problem of plugging? Yes. 1. Some people proposed to remove the ink cart, directly add boiling water to the ink absorption pad, restore the ink cart, turn on the machine and perform a cleaning after two hours, to see if it is OK, do not worry about damaging the machine if the water leaks. This method has some unique insights. I also use this method to repair many older printers. The specific reason is that the printer has not been used for a long time, the rubber around the ink absorption pad is dry and cracked, and the nozzle can not be completely sealed around the ink absorption process, resulting in air leakage. The ink cannot be absorbed correctly, causing the print head to fail to print colors or individual colors. At this time, we only need to drip full water on the ink absorbing pad to allow the rubber around the ink absorbing pad to fully absorb water, and some faults can be eliminated. As mentioned above, don't worry about damage to the machine. This is mainly to prevent water from splashing on the printer head circuit board. But I disagree with boiling water. On the one hand, the higher boiling water temperature accelerates the aging process of rubber. High temperature does not necessarily have a good dredging effect on the condensed ink, but it does have a certain auxiliary effect. The main effect on dredging is still water. Can we replace it with warm water? After being diluted, the clear solution dripped on the ink absorption pad, which can also clear the nozzle, and it is faster and more effective. However, the above method only has a relatively good effect on the crystal plug on the surface of the nozzle outlet. For the crystallization inside the nozzle, especially the high-density filter inside the nozzle, there is no big effect. 2. How should we deal with the internal crystallized spray head? Generally, we can use a syringe and a rubber tube to directly sleeve on the ink absorption column of the print head. Add about 1 ml of cleaning solution to the syringe and push gently. At this time, we can hold a piece of printing paper under the nozzle, and the waste ink will be absorbed by the printing paper, so that it will not be filled with ink everywhere. Now there are some sponge-free ink cartridges from manufacturers, which have better help for cleaning nozzles. We only need to dilute the special cleaning solution according to the proportion and add it to the sponge-free ink cartridge. Of course, you can also add some ink to the cleaning solution, and you can see the cleaning results through the test strip while cleaning. Regarding the unclogging of the print head, we can't get 100% of it done. We can fix 80% to 90%. I believe that even EPSON cannot do 100%. Therefore, according to the correct method, to ensure that it can be used again is the key to our cleaning.

(3) If the above method still can not solve the problem, comrades who are relatively experienced in printer maintenance can remove the nozzle and the nozzle is up, find an object to support the print head, so that the surface of the print head is horizontal to the ground. (A certain level) Then drip the cleaning fluid on the nozzle surface in sequence. After a few minutes we will see that the cleaning solution has mixed ink and is dripping from the ink absorber.
