1.Inkjet Printer Introduction
The companies that repair the print head of the inkjet printer include: thumb print head repair network, and UV-curable ink is a newer product. Organic Compound volatile organic compounds), and suitable for a variety of substrates, there is a large room for development. The inkjet printers used in the market today are generally 3.2 meters or 5 meters, and are mainly used in the advertising industry for large-scale outdoor advertising.
At first, the inkjet printers used in China were imported, with high precision and high price. With the development of the domestic inkjet industry, except for the main core components that are imported (such as nozzles), the rest of the components have basically been localized.
2. Brand of inkjet printers
Nowadays, the inkjet printer nozzles used in China are basically foreign brands. Four mainstream nozzles, including Nika nozzles, British XAAR (Xaar), and American Spectra.
Japanese nozzles
Manufactured by Seiko Electronics Group, Seiko was first known all over the world in the production of precision clocks, and now it is in the production of container pressure In terms of electric nozzles, it already has quite strong strength and foundation. In terms of stability, it is just as high-quality as the Seiko watches it produces. The only agency in the country is owned by Shanghai Feiyang United.
The SPT nozzle is finally designed by combining the performance advantages of all previous nozzles. While focusing on the advantages of the past, it is also mainly reflected in:
a. It is mainly characterized by an all-stainless steel design, With super durable life, each nozzle has 510 pipes.
b. The print head voltage can change with the temperature, so it can solve the trouble of ink breaking caused by external factors such as temperature in other print heads in the past.
c. The data port of its print head can adapt to different printing software, and the printing density is more reliable than the previous print head?
d. It can be produced in a variety of modes, and the ink dot particles It is 35PL and 12PL, the highest standard precision is 720DPI and 1440DPI, and the color saturation is impeccable.
e. The print width of the print head is 75mm, which is 4 times that of the ordinary print head, and it can output quickly.
f. It has a wide range of applications and has now been used in the scope of industrial and commercial printing.
g. The production lines of the matching inks are all tested by the professionals of the Japanese Seiko Electronics Group, and the inks produced each time are all certified by the Seiko Group before they can be put on the market.
h. The cost is lower and tends to be popularized.
Nowadays, the brands that mainly use Japan’s Seiko SPT nozzles are: Feiteng, Extreme, Jinghui, Gongzheng, etc.
Japan series
Konica nozzle is a newly promoted Japanese brand. , It is also successful in hardware facilities, but there is too much water in domestic agents. Among them, the Konica Minolta 512 nozzle, according to scientific calculation, its ink dot size is only 56/28PL, and its accuracy is also about 720DPI, but its in The publicity of 42/14PL has misunderstood many consumers. In addition, its ink is not provided by professional manufacturers, and the supervision on the ink production line is not very strict. Among them, the most successful inkjet printer using Konica nozzles is only Yaselan, but due to the brand effect, its price is also high in the same industry, and there is no certain flexibility in after-sales service.
Nowadays, the brands that mainly use Japanese Konica nozzles are: Yaselan, Aowei, Cheetah, West, Maijiet and so on.
The companies that mainly repair Japan’s Seiko SPT nozzles are: Thumb nozzle repair network, nozzle models: Konica 256, 512, 1024.
UK nozzles
The main nozzles produced by XAAR are XAAR128, XAAR500, XAAR126, XAAR382, XAAR600 and other models. Among them, the 126 and 128 nozzles were one of the most widely used nozzles in China in the early days. Today, the 382 (proton nozzles) and 600 nozzles are mainly used.
Nowadays, the brands that mainly use British XAAR (Xaar) nozzles are: Cyber, Liyu, Maijiet, etc.
The companies that mainly repair British XAAR (Xaar) printheads are: Thumb printhead repair net printhead models: Xaar 126, 128, 382
US printheads
Spectra first produced thermal foaming nozzles for office printing, but eventually gave up due to the emergence of HP and turned to research and development of industrial piezoelectric nozzles. Now it has achieved considerable success in this market. The characteristics of its nozzles are that the ink droplets are small (high corresponding precision), the ejection frequency is very high (fast speed), and the ink is not very “picky”. American Witt is the first brand to use Spectra nozzles, and it is also the most popular in the global market. A well-received inkjet printer, the problem with Spectra is that the price of the printhead is too high. Although Wittur has sold hundreds of units in China, the inkjet printer products of several domestic manufacturers that use Spectra printheads have never become mainstream products, and they are mainly exported. It is a lightweight cartridge printhead with precision stainless steel packaging. All components can be moved quickly. It is suitable for printers with superior performance. The main models are SpectraSl-128 and Spectra Nova/80LQ.
Among them, 128 series printheads have many similarities with XAAR128+ printheads in terms of stability and performance, while Nova256 series printheads were basically developed by the printer manufacturer-Witt before the successful development of domestic inkjet printers. For company use. From the perspective of the internal structure of the print head, the part of the print head that directly contacts the ink, the XAAR print head is made of Teflon material, and the Spectra print head is made of steel. The ink has a certain corrosion ability. Due to the steel structure of the Spectra nozzle, the corrosion resistance of the nozzle to the ink is greatly improved first; the ink is pressed out of the nozzle, and the strong pressure can easily deform the diameter of the nozzle. The steel structure of the Spectra nozzle is more than that of the XAAR nozzle Teflon The inner coating of the material is more pressure resistant. Therefore, Spectra nozzles have a longer service life than XAAR nozzles, changing the statement that nozzles are consumables. When it comes to printing speed, Spectra nozzles have several times higher ignition frequency than XAAR nozzles, which greatly improves the printing speed of inkjet printers. In the industry, Spectra nozzles are relatively high-end nozzles, and the market retail price is 30,000 yuan/piece , but gradually faded out of the domestic market due to its high input cost.
In 2010, Spectra launched the brand new Polaris sprinkler.
Nowadays, the brands that mainly use American Spectra nozzles are: Caishen, Honghua, Gongzheng, Desai, etc.
The company that mainly repairs Spectra print heads in the United States: Thumb Print Head Repair Network
3. Other brands of inkjet printers
Foreign Mainly Japan and the United States and other manufacturers: Sai Angel, Witte, etc. Among them, Hewlett-Packard also has corresponding products. The price of foreign products is generally higher than that of domestic products, but the corresponding accuracy and life are also good.
4. Inkjet printer maintenance skills
The problem of nozzle clogging of the inkjet printer [3] during use is mainly caused by “Prevention first”. The best way to keep the nozzle in the best working condition is to do some proper and effective daily maintenance on the nozzle every day, which will greatly reduce the possibility of nozzle blockage. Therefore, please read the following contents carefully and refer to the operation.
One. After the equipment is installed, and the maintenance of the sprinkler at the beginning of the equipment’s operation
1. In order to make the print head into the best operating state, before the equipment officially starts to undertake the production business, please be sure to use 1-2 days to print as many pictures as possible. 4 color bars of C, M, Y, K should be added on both sides to ensure that the 4 nozzles are always in the inkjet state.
2. When painting, it is best to take out the moisturizing sponge in the cleaning station on the far right together with its bracket.
Second. How to maintain and maintain the printhead after each day’s work
After all printing jobs are completed each day, in order to keep the printhead in the best working condition and avoid clogging the nozzles due to the volatilization of solvent-based ink, please Allow the unit to stay overnight after maintenance of the sprinkler head as follows.
1. Power off the device.
2. First clean the moisturizing sponge with a special cleaning solution, then pour the cleaning solution on the sponge to soak it.
3. Move the handpiece back to the far right cleaning station and allow the nozzle to tightly engage the moisturizing sponge.
4. Leave the device in this state overnight.
Three. What to do when the nozzle is found to be slightly clogged
1. If the nozzle is found to be slightly blocked during the printing process, press the PAUSE button without hesitation to suspend the printing operation, and then use a vacuum cleaner or a manual air pump to spray the ink from the nozzle to clean the nozzle. After cleaning, use a plastic squeeze bottle to the nozzle. Spray some cleaning fluid on the surface to wash off the residual ink.
Note: Do not use excessive force when using the manual air pump, otherwise the nozzle will be damaged due to excessive pressure.
2. Dealing with minor nozzle blockages promptly, decisively and thoroughly is very important to keep the nozzles working at their best during long printing sessions!
3. In addition, it is also necessary to carefully check the condition of the nozzle and find the reason for the nozzle blockage.
Four. How to deal with frequent nozzle clogging in the process of printing
1. First press the PAUSE key to pause the printing operation, and then press the PURGE key to move the machine head to the leftmost cleaning position.
2. Keep the power of the device on, and unplug all the signal wires of the liquid level sensor connecting the auxiliary ink tank to the control board of the machine head.
3. Unplug the ink supply tube (from the auxiliary ink tank) on the print head, and then use a glass syringe to extract the special cleaning solution to clean the print head. Method: Use 40ml of cleaning solution each time, once every 10 minutes, a total of 3 to 4 times.
4. After cleaning, re-plug the ink supply tube and the liquid level sensor signal line, and then resume the previously paused print job.
5. The processing method when the above processing methods are not effective or temporarily ineffective
1. Remove the printhead from the printhead tray.
2. Pour an appropriate amount of special cleaning solution into a clean glass container (for example: a beaker), it is advisable to submerge the bottom of the nozzle by 2-3mm after placing the nozzle, and then seal the glass container with plastic wrap (anti-ash) and let it stand for more than 1 day .
Note: The signal interface at the top of the print head must not touch the cleaning fluid, otherwise it will damage the print head.
3. After the nozzle is soaked, pour an appropriate amount of special cleaning solution into the printer nozzle cleaner, then put the bottom of the nozzle into the cleaning solution and immerse it for about 2-3mm, then start the cleaner and select a special nozzle cleaner. The cleaner must strictly control the time to prevent damage to the nozzle.
Note: Do not use the washer more than three times in a row.
4. Use a glass syringe to extract 40ml of special cleaning solution, inject it from the interface of the ink supply tube at the top of the nozzle, and observe the state of the water line ejected from the nozzle. If all the water lines are straight, it means the cleaning is effective, and the nozzle can continue. Use (premise: both the circuit and the piezoelectric crystal are in good condition), if there is still some waterline spraying crooked, you must repeat steps 2 and 3 for 2 to 3 times.
Six. Processing method when the device is expected to be unused for more than 48 hours
If the device is expected to be unused for more than 48 hours, the ink in the nozzle must be cleaned, otherwise the ink in the nozzle will be Because the solvent gradually evaporates and dries up, it can even cause irreversible damage to the nozzle. The processing method is as follows:
1. Power off the printer.
2. Move the machine head to the leftmost cleaning position, and place a corrosion-resistant container under the nozzle to hold the cleaning waste liquid.
3. Use a glass syringe to draw out or directly pour out the ink in the auxiliary ink tank, and then clean the auxiliary ink tank with a special cleaning solution.
4. Unplug the ink supply tube (from the auxiliary ink tank) on the print head, and then use a glass syringe to extract 40ml of special cleaning solution to clean the print head, a total of 2 times. Finally, do not blow off the cleaning liquid remaining in the nozzle, and be sure to leave enough cleaning liquid inside the nozzle, because the cleaning liquid can moisturize the nozzle.
5. Put the treated sprinkler in a clean, corrosion-resistant container and seal it (with plastic wrap is good), and it can be stored for about 1 month.
5. Inkjet printer nozzle maintenance skills
The inkjet printer nozzle is the core of the inkjet printer. If the nozzle is broken, it will be scrapped. Buy a new one. Not cheap. Therefore, the maintenance of the nozzle of the inkjet printer is very important.
Common faults of the print head of the inkjet printer: the inkjet printer head is broken, the printhead is blocked, the printhead is dropped, the printhead is slanted, the printhead is deviated from the needle, the printhead is disconnected, and so on.
To sum up, most of the common situations mentioned above are caused by the clogging of the nozzle and improper operation, so we must pay attention to the maintenance during the operation.
