Most of the failures are due to the long-term non-use of the printer or other reasons, resulting in obstacles in the ink conveying system or nozzle blockage.
The way to eliminate it is to clean it.
2. After replacing the new ink cartridge, the ink on the printer panel will be opened when the printer is turned on.
Under normal circumstances, when the ink runs out, the ink outlet lamp will light up. After replacing the new ink cartridge, the out of ink indicator on the printer panel is still on. This kind of failure may occur. One is that the ink cartridge is not installed, and the other is that the old ink cartridge is taken down and replaced when it is turned off. Because after replacing the ink cartridge, the printer will fill the ink feeding system, and this process will not be carried out when it is turned off, so the printer cannot detect the reinstalled ink cartridge. In addition, some printers use the electronic counter inside the printer to count the ink capacity (especially when counting the usage of color ink). When the counter reaches a certain value, the printer judges that the ink is exhausted. During the process of replacing the ink cartridge, the printer will reset its internal electronic counter to confirm the installation of the new ink cartridge.
Solution: Turn on the power supply and move the print head to the ink cartridge replacement position. After installing the ink cartridge, let the printer fill the ink, and after the ink filling process, troubleshoot.
3, nozzle soft plug processing
Soft plug blockage refers to the disconnection failure caused by the increase of ink viscosity on the nozzle for various reasons. Generally, the original ink cartridge can be restored by repeated cleaning, but this method is too wasteful of ink. The easiest way is to clean the nozzle with the empty ink cartridge in your hand. Before cleaning the empty ink cartridge, use a needle to pump out the residual ink in the ink cartridge as cleanly as possible, and then add He Zhi 96 1 cleaning solution. 96 1 cleaning solution is specially developed for epson, and it can be divided into solution a and solution b. solution a has strong cleaning ability and can be used for the treatment of moderate blockage, but it can't stay in the nozzle for a long time. The cleaning ability of solution B is weak, but the safety factor is high. This solution can be mixed with 2 (solution B): 1 (Epson red or blue ink), and the mixed semi-color ink is used for semi-color ink of Epson photo cartridge. When filling the cleaning solution, it should be carried out in a clean environment. According to the normal operation of the printer, load the ink cartridge with cleaning liquid into the printer, and keep pressing the cleaning key of the printer for cleaning. Use the light mixed cleaning solution of the remaining ink in the ink cartridge for printing test. After normal, replace the ink cartridge and use it.
4, nozzle plug processing
Hard plug refers to the blockage caused by chemical solidification or impurities in the nozzle. This kind of fault is difficult to eliminate and must be handled manually. First of all, remove the nozzle, soak it in solution A, backwash it and clean it under pressure. After washing, clean the cleaning solution with pure water, and then dry it to install. As long as the hard object does not damage the nozzle electrode, the cleaned nozzle is still good.
5, printer cleaning pump nozzle fault handling
There are many problems in the nozzle of the cleaning pump of the printer, which is also one of the main factors causing the blockage. The nozzle of printer cleaning pump plays a decisive role in the protection of printer nozzle. After the nozzle trolley returns to its original position, the nozzle of the cleaning pump is used for weak pumping treatment and sealing protection of the nozzle. When a new ink cartridge is installed in the printer or the nozzle is damaged, the suction pump at the lower end of the machine will use it to pump air to the nozzle. The higher the working accuracy of this nozzle, the better. However, in actual use, its performance and air tightness will be reduced due to the extension of time and the increase of dust and ink residue in this mouth. If users don't check or clean it frequently, it will make your printer nozzle break down constantly.
The way to maintain this part: take off the upper cover of the printer, take off the trolley, and wash it with pure water inhaled by the needle tube, especially the microporous gasket embedded in the mouth. Here, it is necessary to remind the user that when cleaning the part, it must not be cleaned with ethanol or methanol, which will lead to the dissolution and deformation of the microporous gasket embedded in the part. In addition, the inkjet printer should be as far away from the high temperature and dust working environment as possible, and only a good working environment can ensure the long-term normal use of the machine.
6. Check whether the ink line is normal and whether the printing accuracy is obviously worse.
In use, due to the extension of the number of times and time of use, the printing accuracy of the inkjet printer will gradually deteriorate. Inkjet printers also have a long life. Usually, a new nozzle is used from the beginning to the end of its life. ............................................................................................................................................................... >
Question 2: How to prevent the nozzle of the printer cartridge from blocking and not using inferior ink? Any brand of ink will do, but it should be used with caution.
If you don't use the printer for a long time, it is best to print a full picture with rich colors once a week to ensure that the nozzles of each color will not dry up and block. Print at least one copy every month.
Unless absolutely necessary, do not insert or remove the ink cartridge, and do not insert the needle tube into the inner ink cartridge to extract ink or air, so as to avoid air leakage from the ink cartridge gasket. Even the smallest air leakage will form tiny bubbles into the nozzle, resulting in stripes or color cast.
Abnormal printing, don't judge nozzle blockage easily. It is not common that the nozzle is really blocked. Most blockages are actually excessive air entering the internal ink cartridge.
The way to distinguish between horizontal stripes, that is, the nozzle is blocked or there is too much air in the ink cartridge:
Before and after cleaning the nozzle, if the nozzle detection mode is fixed, the nozzle is blocked. You can use the nozzle disassembly-free technology to clean the nozzle. Dismantling the nozzle is easy to damage the nozzle or the head line; The use of alcohol can easily increase the affinity of nozzle surface to ink, resulting in cross-color; Pressuring the nozzle with a needle tube is easy to cause the cavity to crack and scrap; Soaking nozzle is easy to be burned due to electrical short circuit. Once the nozzle is burned out, it can't be repaired and can only be replaced. The nozzle is the most expensive part of the printer.
Before and after cleaning the nozzle, the position of the broken line has changed obviously, which is because there is too much air in the inner ink box and the ink supply is not smooth. It is recommended to use safe exhaust technology to exhaust excess air. Safe exhaust technology can ensure the safety of nozzles and ink cartridges.
The storage time of ink should not be too long. Once the ink is opened, it should not be more than half a year from the factory to the use. Don't believe the two-year warranty.
Once the ink is added incorrectly, it is better to replace the ink cartridge (or even replenish it), which is a pity. Ink is cheap, but nozzles are expensive.
Do not clean the nozzle unless absolutely necessary. Clean the nozzle continuously, no more than 3 times. Cleaning the nozzle many times will not only accelerate the aging of the nozzle, but also burn it out.
Please be kind to the nozzle. Under normal use, the nozzle is not so easy to be damaged. But the nozzle is exquisite and unbearable.

Question 3: What should I do if the nozzle of Canon printer cartridge is blocked? Plug, you mainly add ink yourself. There is no other way but to take it to the maintenance station for washing. . If you can't wash it off, you have to change it!
Question 4: How to clean the ink in the blocked ink cartridge of the printer? Clean the nozzle quickly without disassembling the nozzle!
Publisher: Administrator Date of Publication:128/2008 9: 34 am:14
Dye ink is mature and generally does not cause permanent blockage (unless the ink is too poor). "Blocking" is just a fake. We can sum up the following ten situations:
1: Dirty plug is generally caused by scraper failure, dirt and long-term use of inferior paper with paper wadding.
2. Miscellaneous plug means that tiny objects in the ink enter the nozzle and block the ink outlet.
3. The screen is blocked. If you use inferior ink for a long time, the larger substances and harmful solvents in the ink will be blocked in front of the screen, and it will be blocked for a long time.
4. Dry congestion is often not caused by a long time.
5. Chemical plug, often using different kinds of ink to cause chemical reaction, leading to glue blocking the nozzle.
6. Bacterial corruption and blockage: This kind of blockage mostly occurs above 20 degrees, and the bacteria in the ink multiply in large quantities, which leads to the deterioration of the ink and the appearance of flocculent corrupt substances in the nozzle.
7. Scaling and blockage: Due to improper treatment of water by some inks in the manufacturing process, mineralized substances in water will scale on the nozzle after long-term use, resulting in the effective diameter of the nozzle becoming smaller, often starting from the horizontal stripes on the printed matter.
8. Oily blockage, the ink truck needs lubricating oil, sometimes lubricating oil will spread to the nozzle, changing the physical properties of the nozzle, resulting in a similar blockage phenomenon.
9. Electrical plug. Some printer nozzles are equipped with ink or ink cartridge chips for electrical performance testing. When non-standard ink or chips are detected, the ink valve will be closed to varying degrees, so that the ink cannot pass through the nozzle normally. This kind of plug is called a fake plug.
10: air plug, some inks have poor defoaming performance, and bubbles will be generated in the ink. Once bubbles enter the nozzle, it is difficult to come out, resulting in air plug.
Knowing these ten points, it is relatively simple to clear the blockage.
A, prepare cleaning solution and tools.
B, remove the print head, remove the inner box, unplug the power supply (unplug the power supply without turning it off to discharge the remaining power of the printer).
C, insert one of the silicone tubes into the small rod of the nozzle, and pump it upward.
D, use another hose to suck out 3-5ML of cleaning solution, and force it in. When driving in the cleaning solution, pay attention to tighten the two red boxes and do not spray the cleaning solution.
E. After 15 minutes, there is no problem in installing continuous supply or solving the ink cartridge problem.
Remarks: The above operations can be repeated for people with serious traffic jams, and this method is equally effective in dealing with horizontal stripes.
Hot bubble nozzle
If it is slightly blocked, don't remove the nozzle, turn the nozzle upside down, drop 3-5 drops of cleaning liquid on the nozzle array, and after 5- 10 minutes, slightly suck ink with an ink suction pump to test printing.
For the old nozzle that is seriously blocked, soak the nozzle part for 24 hours with cleaning solution (to avoid soaking the contact part of the circuit), use Mo Dou pump to suck it and try to print it on the machine.
Piezoelectric nozzle
Piezoelectric nozzle is a long-life design nozzle. In addition, due to the manufacturing process of the nozzle, the nozzle has a large aperture and no heating elements, so it is generally not easy to block. If the blockage is serious, you should consider replacing this ink immediately, because this ink is not worthy of being called ink at all. Ink can be replaced, but blocked nozzles can be treated with cleaning solution. If it is convenient to remove the nozzle, soak the nozzle part downward in the cleaning solution, and do not soak the circuit board. For no more than 30 minutes, suck 20 ml of cleaning solution with a syringe and press it out along the ink outlet direction of the nozzle. Finally, clean and install the test nozzle with purified water. Think again, even the piezoelectric nozzle can be cleared! Of course, from the choice of ink, we must choose good products, and ink of unknown origin must be used with caution. Pay attention to the cleanliness and tightness of the ink path when operating. In actual printing production, there may be many other factors that lead to broken lines, lack of color or even no ink.
Question 5: How to solve the problem of printer nozzle blockage? Generally speaking, if an inkjet printer is used under normal circumstances.
There will be no congestion, but many users will not follow the instructions completely. For example, using the original ink cartridge is expensive and uneconomical, so filling it yourself and then printing the picture may appear color cast, blur, lack of strokes and so on. What's more, some people have bought printers and left them on the shelf after not using them several times. When they need to use it for a period of time, they find that the ink in the nozzle is dry and they can't print at all. Then the author will share with you the experience summed up in actual combat in recent years. If your printer needs to be filled with ink, or there is a similar nozzle blockage, how should you solve it?
Methods to solve the phenomenon of nozzle blockage
A friend of the author used Lenovo inkjet printer. After she ran out of random ink, she went to the computer city to buy ink herself, and then asked my master for help. According to the ink filling method of the general printer, the author fills the ink with a syringe, and the printer can be used normally. What is depressing is that the printed picture has a serious color cast phenomenon, and there is no way to express the original picture normally, and the text is basically no problem. It took a long time for the author to make sure that he didn't mix up the color ink when filling the ink, but he still had no clue. When he wanted to give up buying new ink cartridges, he suddenly thought of a good friend who runs consumables products in the computer city. I called for advice, and it was also a word that woke up the dreamer. The other party told the author that this may be because there is still residual color ink in the ink cartridge, and the density difference of the newly added ink is inconsistent, which leads to problems in printing. So the author used a syringe to extract all the ink from the ink box, and then refilled it with compatible ink, and the problem was solved. Another time, when other friends were using the printer, they found that the printed fonts were sometimes incomplete, and there was a phenomenon of pen leakage, which was also a problem after ink was filled. According to experience, the author immediately concluded that there are several reasons for this phenomenon. First, the ink jet head was accidentally damaged when adding ink, resulting in incomplete ink jet (some ink jet heads have no ink); Secondly, the quality of the purchased ink is poor, the ink droplets are relatively large, or there are impurities, which block the inkjet head; The third is that air enters the ink box when filling ink, which leads to bubbles in the ink and poor ink circulation; Finally, it may be because the ink cartridge has been placed for a long time, and the ink in the nozzle has dried up, blocking the nozzle.
The above four doubts are also the most common causes of nozzle blockage in printers at present. The author will briefly explain their respective countermeasures for these four murderers, hoping to help everyone and prevent the blockage from happening again.
First of all, we have no choice but to replace the inkjet head in the first case of damage. Therefore, it is recommended that you avoid mechanical collision and vibration when replacing ink cartridges, refill kit and daily use. In the second case, we suggest that when filling ink, filter the ink with filter paper first, and then put it into the ink box. It is worth noting that when refill kit, don't pierce the filter inside the ink box, so as to avoid the broken fibers mixing into the ink and blocking the ink jet head. The solution to the third case is relatively simple. We just need to shake the ink in the ink box evenly, just like we usually shake the ink box a few times when we use a pen. However, it should be noted that the ink cartridge must be held tightly when it is dumped, or it will be completely finished if it falls to the ground. For the fourth case, we can clean the ink head, provided that we check whether the ink is used up first. Then use the cleaning program inside the printer to clean the inkjet head of the printer, which can generally solve the problem. If it doesn't work, we will use an external cleaner. At this time, we can do this. First, turn off the power and open the cover of the printer. Then turn on the power supply, and when the ink cartridge moves outward to the limit position, unplug the power supply, so that there is enough space to clean the ink head. At this point, we can dip some alcohol in the cotton ball, wipe off the ink on the nozzle, pay attention to the humidity of the cotton ball, and don't let the alcohol overflow. After cleaning, power on, the ink cartridge will automatically reset, and then we will wait for another hour, and the printer will be as good as new. In addition, if it is determined that the ink in the ink cartridge is a dye component, the nozzle can be taken down and soaked in warm water to let the water dissolve the dye, thus solving the problem of nozzle blockage. However, if you are in refill kit ...
Question 6: What should I do if the nozzle of the ink cartridge is blocked? Specific cleaning methods! This question should be simple. After the nozzle was blocked, although you cleaned it, you didn't clean the print head thoroughly. After cleaning, the print test page is displayed perfectly, and then the print task on the next page is defective. It is usually necessary to analyze this situation: after cleaning, the results of printing unused ink on the print test page are printed,
I have used several Epson inkjet printers, and I often encounter situations like yours, but I solved them myself.
Suggestion: If the nozzle is easy to disassemble, it can be folded down for cleaning. (pay attention to cleanliness. Anyone who uses an inkjet printer should have an auxiliary tool syringe, which can be used to push (blow) the print head, as well as an ink cartridge pipeline that cannot be ignored. You should also push and suck at the same time. Try it, it will work.
Question 7: If the printer nozzle is blocked, can I just replace the ink cartridge? Just change the print head. Before changing, soak it in alcohol or warm water to see if it can be soaked well. If you can't bubble, change the print head!
Question 8: How to clean the blocked ink head of the printer and simply solve the nozzle blockage?
Many friends have encountered the problem of nozzle blockage when using inkjet printers. Under normal circumstances, everyone repeatedly executes the "cleaning" operation in the printer control software to solve this problem, but this method will waste a lot of ink; Some friends use alcohol to clean it, and the effect is good, but it is not suitable for all products, and it may have a certain impact on the nozzles of some materials.
In fact, if you have enough patience, a few drops of water can completely help you solve this problem:
First, take the ink cartridge (nozzle) out of the printer (be careful not to damage the printing nozzle) and turn the printing nozzle horizontally (be sure to seal the ink injection port of the ink cartridge in advance to prevent ink from flowing backwards). Drop a drop of water with a dropper and gently drop it on the printing nozzle, so that the water can slowly penetrate into the nozzle. If the water is dry, put it down again. This is repeated until the dry ink on the nozzle is soaked by water droplets (generally it takes 4- 10 minutes).
Finally, reload the ink cartridge (nozzle) into the printer. If you are not at ease, you can put pure water into clean old ink cartridges and clean them once or twice.
Detailed explanation of nozzle blockage fault of inkjet printer
Ink-jet printer is a common home office product, which has the advantages of low price, bright color and realistic image reproduction. After the ink jet printer is used for a period of time, the nozzle is often blocked, which seriously affects the printing effect and even leads to the nozzle being scrapped and beyond repair. Here is a detailed description of the nozzle blockage fault of the inkjet printer.
First, understand the nozzle of inkjet printer
At present, there are two main structures of nozzle and ink box of inkjet printer: one is integrated nozzle and ink box, and the other is separated nozzle and ink box. When the ink in the integrated nozzle cartridge is used up, the nozzle and cartridge should be replaced together. The nozzle with separate structure is separated from the ink cartridge, and the ink cartridge can be replaced separately after the ink is used up. Nozzle structure can also be divided into single nozzle and double nozzle. At present, most printers on the market (such as EPSON and CANNON) adopt double nozzle structure: a black (or photo) ink head and a color ink head.
Second, the nozzle clogging reasons
There are several reasons why the nozzle is blocked: First, the environment in which the inkjet printer is used is not clean, and there is too much dust, or there is too much dust on the printing paper, so it is easy to block the nozzle when entering the printer; Second, the quality of the ink purchased is poor, the ink drops are relatively large, or there are more miscellaneous brands, which blocks the nozzle; Thirdly, different brands of ink are often changed, because different brands of ink have different chemical compositions, and chemical reactions may occur after contact with each other, resulting in damage to ink cartridges and nozzles; Fourthly, when filling ink, air enters the ink box, resulting in bubbles in the ink and poor ink circulation. Fifth, because the printer is not used for a long time or the nozzle seal is not tight after normal printing, the ink in the nozzle dries up, causing blockage.
Thirdly, the treatment of ink jet head blockage.
For the blockage caused by the increase of ink viscosity on the nozzle, the nozzle cleaning function in the printer driver is generally used for cleaning, or the cleaning button on the printer is used for cleaning. This method is simple to operate, but the cleaning effect is not thorough, and the cleaning times should not be too many, usually about three times, and it also wastes ink.
It is troublesome to deal with the blockage caused by ink condensation or impurities in the nozzle. Generally, there are three ways to solve it:
1。 Clear water immersion method
Use a small container to hold warm water with a height of 1cm and a temperature of 6℃, then soak the ink outlet end of the printer nozzle in warm water for several hours and take it out (be careful not to let the PCB board touch the water), then carefully dry the water on the print head with absorbent paper, and finally put the nozzle back into the printer. I just printed some. Maybe the color is lighter. Print a few more copies and it will be back to normal.
2。 Pressure cleaning method
Use the plastic tube or needle of disposable infusion set to make the syringe combine with the ink supply port of the print head (the combination position must be tight), put the head of the nozzle into 95% organic solvent alcohol, and suck the alcohol into the needle tube of the syringe through the nozzle (note that it can only be inhaled) several times. It should be noted that when inhaling alcohol, the force should be uniform and continuous before and after, so that the nozzle will not be damaged generally. This method has a good cleaning effect. Generally, nozzles with serious blockage can be cleaned by this method, but it requires high hands-on ability.
3。 Clean water cleaning method
Clean water cleaning method is suitable for printers with separated nozzles and ink cartridges in the market at present. First of all, find some ink cartridges on this printer, pry them open, take out the sponge inside, put a new sponge in, and put it in before ... >>
Question 9: What should I do if the ink cartridge is blocked? What should I do if the ink cartridge nozzle is blocked? What if the ink cartridge is dry? Mainly you add ink yourself. There is no other way but to take it to the maintenance station for washing. . If you can't wash it off, you have to change it!
Question 10: How to deal with the nozzle blockage of Epson printer? Inkjet printers, which used to be defined as household products, are increasingly appearing in various applications. This is of course due to the rapid development of inkjet printing technology, which provides us with more application options in printing office. However, the "congenital deficiency" of inkjet printers has not been well solved-nozzle blockage.
There are many reasons for nozzle blockage, such as not printing for a long time, or ink impurities, or nozzle wear and so on. Here are some ways to solve nozzle blockage, hoping to help you quickly eliminate nozzle blockage.
1. Ink head structure of ink-jet printer: There are two common ink head structures of ink-jet printer: integrated ink head and separated ink box. After the ink cartridge is used up, the ink head and ink cartridge with integrated ink head structure should be replaced together, which is more compact and reliable, but the relative cost is higher; The ink head and ink box with separate structure are separated, and the ink box can be replaced separately after the ink is used up, which can save costs to some extent.
Second, the formation of "blockage" of inkjet printer: due to poor sealing or long-term storage after normal printing of the print head, excessive evaporation of water leads to the drying of ink particles at the tip of the fine print head, which makes the ink unable to be ejected normally; Or different inks are mixed with each other, resulting in chemical reactions, which are usually manifested as frequent faults such as broken lines, color leakage, blurred handwriting and even failure to print normally.
Classification of "plugs" of inkjet printers: They can be roughly divided into two categories: soft plugs and hard plugs.
(a), soft plug repair:
1, and the soft plug refers to the disconnection fault caused by the increase of ink viscosity on the nozzle for various reasons. Sometimes it is only attached to the nozzle surface of the ink outlet, and it can be recovered after being soaked in the original ink for many times. Its advantages are simple and quick operation without any physical damage; The disadvantage is that the use cost is high and ink is wasted.
2. Use the print head cleaning function in the application tool of the printer driver for cleaning. Its advantages are simple and quick operation; The disadvantage is that the cleaning effect is not ideal.
Note: 1. Generally, the above two cleaning methods should not be more than three times. When the printer "paper jam" is not serious, it should be washed within three times. If you can't flush it after three times, it means that the blockage is serious, and no matter how you clean it, it may not work. There is no point in romanticizing a lot of expensive ink. At this time, further treatment should be done according to the specific situation;
3. Due to the phenomenon of "air resistance" between the ink cartridge (such as sponge filling type) and the print head, there will be a small amount of irregular disconnection, so it is not necessary to clean it repeatedly at this time, and it can be used normally after being placed for a period of time.
4. Avoid ink mixing. Don't rush to add new ink to the ink cartridge. First, inhale some ink with a clean disposable syringe, and observe it carefully in a bright place to see if there is suspended matter in the ink. If there is suspended matter, do not mix it. Then inhale a little ink from the used ink cartridge and mix it with the newly bought ink, and then let it stand for 24 hours before observing to see if the mixed ink has a chemical reaction. If there are changes (such as crystallization, etc.). ), indicating that the compatibility of the two inks is not good, and mixing is prohibited.
