How to ensure uv printer nozzles can be used for a long time

The UV printer head is very important. If there is a problem with the print head, the printer will strike and cannot be used for production. The nozzle is a high-precision part that may be damaged or clogged due to your slight inattention. The flatbed printer nozzle is composed of a large number of small nozzles. The size of the nozzle is similar to that of the granular dust. If some small debris or dust enters the nozzle, it will clog and the nozzle panel will be stained with ink, resulting in the phenomenon of ink ejection. Therefore, the maintenance and maintenance of the nozzle is very necessary.

 UV Printer

The nozzles removed from the UV flatbed printer cannot be placed separately, especially at high and low temperatures. If the removed nozzle is left for a long time, the dry ink will clog the nozzle as the moisture contained in the residual ink in the nozzle gradually evaporates. If the nozzle is found to be clogged, the nozzle should be cleaned immediately. If the nozzle is still not used after the cleaning is completed, it is necessary to consider whether the nozzle is broken. If it is broken, replace the nozzle with a new one.
Do not touch the surface of the UV inkjet printer nozzle with tools and fingers, in case of damage to the surface of the nozzle or oil, debris blocking the nozzle. Do not blow air toward the nozzle, and do not put oil, sweat, or alcohol on the nozzle, which will cause the composition of the ink and viscosity changes, resulting in an ink condensation block. Also do not use tissue paper, lens paper, cloth, etc. to wipe the nozzle surface.

 Inkjet UV Printer

Do not suddenly turn off the power while the UV printing machine is working. If some models of printers are suddenly turned off, the printer will not be able to perform a cap operation on the nozzles, causing the nozzles to be exposed to air and the ink to dry up, causing the nozzles to become clogged. The correct way is to turn the UV flatbed printer to the OFFLINE state after the nozzle is capped, turn off the power, and finally unplug the plug.

Wide-format UV inkjet printer nozzles are high-precision equipment, and the price is still very expensive on the market. In daily use, it is necessary to pay more attention to the maintenance of the nozzles, and master some tips for using the nozzles, so as to make the nozzle use longer, to save time and money to work production.

After the uv inkjet printer nozzle is blocked, how to clear it?

During the use of uv inkjet printers, improper operation sometimes causes nozzle clogging, which affects printing efficiency and causes unnecessary loss. Because the nozzles are not cleaned in time, the uv printer nozzle clogging damage will be further increased. Several nozzle cleaning methods, I hope to help everyone.

The first type: the scope of application of the immersion method: the resistance is lighter

Step 1: 

Prepare a small flat plate, place the nozzle flat in the tray, and then inject the special cleaning solution for the uv flatbed printer into the tray. The depth is just to immerse the nozzle part. Be careful not to splash water on the cable plug and drive. On the board, the first soaking time is about one hour.

Step 2: Cleaning

 UV Inkjet Printer

1. Gently suck the water stain on the nozzle with a damp cloth. Do not wipe the nozzle at the bottom of the nozzle.
2. Repeat the process for all nozzles to be cleaned. Use a clean area for the cloth for each nozzle.
3. If the nozzle is clogged, the distilled water can be slightly heated and placed in a small amount on the plate. When the nozzle is placed on the plate, the water surface should not leak higher than the bottom 2CM because the water may leak to the back of the chip.
4. Stand the nozzle upright in warm water. Wait for 30 seconds, then test the nozzle after sucking dry.
5. Each nozzle should be cleaned with clean water.

The second type: nozzle injection flushing method Scope of application: severely blocked.

Tools: 95% alcohol, a clean cup, a syringe, and an infusion set.
Working principle: Using the pressure generated by the siphon action of the syringe, an organic solvent such as alcohol is injected into the print head to clean the dry ink head.
Use a plastic tube of the infusion set, one end is inserted in the 5ml syringe, the other end is inserted into the nozzle ink inlet of the nozzle to be flushed, and the distilled water in the syringe is pressed into the nozzle, so that the pressure is not too large, so as to prevent the water pressure from squeezing the nozzle Internal waterproofing adhesive. This process needs to be repeated several times until it is seen that each of the ink outlets ejects a fine water column. In this way, the blocked nozzle is completely cleaned.

The third type: ultrasonic instrument cleaning method Scope of application: the situation is very serious

UV Printing Machine

Working principle; the ultrasonic cleaning machine is used to generate strong ultrasonic waves, so that the water molecules vibrate violently, and the fine dry ink particles are shattered and dissolved in water to achieve the purpose of cleaning.
The reminder here is that if the uv printing machine nozzle is blocked, stop printing immediately, and check the degree of blockage. If you can't clean it yourself, please contact the uv printer manufacturer to help solve it. Do not blindly disassemble the nozzle.

Large format uv flatbed printing machine What is the uncoated of it?

What is the uncoated of large format UV flatbed printers? what is the benefit? These three are problems that plague new users. If you can't understand the difference well, it is easy to cause a lot of troubles for the use of late devices. Seriously, you may buy equipment that you can't use at all, and you will waste money.

 Large Format UV Flatbed Printing machine

The uncoated UV flatbed printer means that when printing part of the material, printing can be started without pre-pressing the surface of the material. It does not mean that all materials can be printed without coating. This coating-free printing is conditional.For example, the surface of the plastic material can be free of coating, and it is common to have a mobile phone case, a notebook case, and the like. Gypsum ceilings commonly found in building materials can also be printed without coating; however, some can not be printed without coating, such as glass, glazed tiles, metal, etc. Any surface density is high, smooth materials can not be directly printed.
So how is the coating free? The free coating is actually determined by the ink. The UV ink itself contains corrosiveness. In this process, the pigment component in the ink can adhere to the surface of the material to realize the entire printing process.Everyone who prints knows that printing something like glass, tile, or metal can't be printed directly. If you need to do some coating treatment on the material to print, then let's first talk about the benefits of using the coating:

1. The drying speed

The fast processing liquid is prepared by special chemical materials, and it is dried in about three minutes after spraying, especially in the smooth materials such as glass, porcelain and metal.

2.The printing quality is better

 UV Printer

If it is directly printed on some materials, it is mainly smooth and non-absorbent material, the effect is poor, and the effect is remarkable after using the treatment liquid. No matter whether the material is bent or folded for a long time, there will be no cracking or faulting on the surface of the material.

3.Wear resistance, waterproof

Since the composition of the treatment liquid has adhesive components, the adsorption force of the ink and the material after printing is very superior, far exceeding the wear resistance of the untreated state, and the waterproofness of the material after using the treatment liquid is far more than that. The coating state is many times.
Customers who have used uv flatbed printing machine know that 90% of the materials used to print glass, ceramics, metal, leather, etc. must be coated. Because the weak solvent ink directly prints the pattern, there is a great possibility that the ink is piled up and the printing and printing effect is poor. Must do pre-printing.

Wide format uv flatbed printer common machine failure and some solutions

Wide format uv flatbed printer breaks through the bottleneck of digital printing technology. It is a high-tech, free-form full-color digital printing machine that realizes a true printing, no plate making, full color image. Finished at once. It is not limited by any materials, and can meet the high quality and high requirements printing of many industries in metal, glass, leather, ceramics, wood, bamboo, cloth, T-shirt, plastic, silicone, MDF, PVC, acrylic, advertising materials, etc. demand. The color printing UV flatbed inkjet printer has been printed at one time, with rich and colorful colors, abrasion resistance, UV protection, simple and convenient operation, and fast printing image. The following are some of the faults that flat panel printers often see in daily use.

Wide Format UV Flatbed Printer 

1. UV flatbed printer nozzle blockage: The cause of the blockage of the UV inkjet printer nozzle is mostly due to the precipitation of impurities; partly because the acidity of the ink is too strong, corroding the nozzle. If it is because the printer has not been used for a long time or if non-original ink is added to cause the ink delivery system to be obstructed or the nozzle is clogged, it is best to clean the nozzle. If the problem cannot be solved by washing with water, the nozzle can only be taken down, immersed in pure water of about 50-60 ° C, cleaned with an ultrasonic cleaner, and dried after washing. The failure of the cleaning pump nozzle of the UV printer is also the main cause of the plugging. Cleaning the pump nozzle plays a decisive role in the protection of the printer nozzle. After the word car returns to the position, the nozzle should be weakly pumped by the cleaning pump nozzle to seal the nozzle. When the machine is equipped with a new ink cartridge or the nozzle is broken, the suction pump at the lower end of the machine is used to pump the nozzle. The higher the precision of the suction pump, the better. In actual operation, the performance and air tightness of the suction pump will decrease with time, and the amount of dust and ink remaining in the mouth will decrease. If the user does not
check or clean it frequently, it will cause the nozzle of the flatbed printer to continuously appear like a plug, so the suction pump should be maintained frequently. The specific method is to remove the upper cover of the UV printer and remove the trolley, and wash it with a pure water by a needle tube, especially to clean the microporous gasket embedded in the mouth. It should be noted that when cleaning this part, it must not be used with ethanol or methanol, which will cause the microporous gasket embedded in this assembly to dissolve and deform. At the same time, the lubricating oil cannot be touched to the pump nozzle part, because the grease will deform the rubber sealing ring at the pump nozzle portion and cannot seal the protection nozzle.

 UV Printer

2. The speed of UV flatbed printing machine is slow: after the continuous ink supply system is modified, the original ink cartridges will also be modified. This kind of transformation will inevitably cause the burden of the word car. In the case of heavy load, the word car will move slowly, the belt will accelerate aging and increase the friction between the car and the connecting rod. In severe cases, the word car cannot be reset and cannot be used.
To solve this problem, it is best to start from three aspects:
(1). Replace the motor, the hose of the continuous ink supply system of the flatbed printer and the wall of the UV printer are rubbed, resulting in increased load on the electric motor, and long-term use of the electric motor is very large. Replacing a new motor can solve the fault;
(2). Lubricate the connecting rod. After the printer has been used for a long time, the friction between the carriage and the connecting rod inside the machine becomes larger, and the increased resistance causes the electric motor to run slowly. Lubrication can solve the fault;
(3). Reduce the belt aging speed, and the frictional force of the driven gear connected with the motor accelerates the aging of the belt of the UV printer. The cleaning and lubrication of the driven gear can reduce the fault of the belt aging.

3. UV printers do not recognize ink cartridges: Users may often encounter this situation when using continuous ink supply: after using the flatbed printer for a period of time, the black ink cartridge cannot be recognized and will not be printed. The main reason for this situation is that the waste ink of the flatbed printer is already full. Because the waste ink is easily formed during the continuous ink supply system, it is easy to cause the waste ink to be full. This situation can be handled in two ways: First, use the clearing software to reset the UV inkjet printer motherboard to eliminate the printer settings; Second, replace the sponge in the waste ink tank at the maintenance point. However, it is recommended that the user adopt the second method, because if it is simply cleared, it is easy to cause the waste ink to leak and burn the flatbed printer. In fact, every uv printer's accessories have a fixed life. When some accessories reach the end of their life, the UV inkjet printer will prompt you to print.

UV flatbed printer,How to distinguish whether it is second-hand or new printer

When we are ready to buy a uv flatbed printer, we must judge whether it is a new printer. If you spend money of new machine to buy an old printer, it will be too bad. Here are a few ways to share with you.

1. Date code.

Open the base of the UV inkjet printer nozzle and observe the internal accessories. Generally, there are date codes on the top. If the date of each component is very different, then the uv flatbed printer has been used for some time, and it has also been replaced by many components.

2. refurbished code

UV Flatbed Printer

The code posted on the print head is the same as the code on the software board. If it is not the same, then the uv printer is second-hand or refurbished. Because the new machine is absolutely the same.

3. Nozzle difference

The effect of the new print head printing is relatively poor when compared to the unused nozzles, because the nozzles will be better and better after a period of use. So when the two nozzles are compared together, you can pay attention. There is also the old nozzle, especially the nozzle that specializes in white ink. Be sure to pay attention to whether the nozzle passage is burnt out and whether the nozzle is blocked.

4. Whether the ink has traces of use

You can check the ink path, the ink tube, and the ink near the nozzle. If there is a description, the nozzle is used.

5. Head parts

UV Printer

The simple method is to look at the old and new parts of the UV flatbed printing machine head parts, open the head of the uv flatbed printing machine, observe the internal parts, the second-hand basic can be seen by the naked eye is old.
The above is a few ways to give some laymen a simple but not uv flatbed printing machine is a second-hand printer, I do not know if it will help you. In addition to the above methods, there may be better, you can also try. Thanks for browsing! Leave a message for me.

If the uv printer printed image is too dark,what should I do?

I don't know if you have such an experience? When you use the uv printer to print patterns, you will find that in some cases, when printing certain materials, the pattern will be particularly dark and will not achieve the desired effect. So what is the problem, and what should we do? In fact, you can try this method, which is to increase the angle of the curve behind the color software, and the specific value of the rising angle needs to be debugged by the technician according to the color condition of the customer pattern, and as long as the standard is met.

 UV Flatbed Printer

So why does the image suddenly fade when the uv flatbed printer prints? Let's talk about some of the reasons that have arisen.
First of all, the amount of ink set in the grade may be relatively low. Generally, in the image control software of the uv printer, the ink output may have different options such as 40%, 60%, 80%, and 100%. Sometimes, some inexperienced people may make mistakes in the original normal ink output, which will make the printed image fade. In this case, we only need to increase the amount of ink.
Then there are different materials that may have an effect on the printing effect. Each material has different gloss, transparency, smoothness, etc. Some materials have a dissolution effect on the ink, and some materials have an adsorption effect, and these characteristics will be The printed effect has a certain effect, and some will make the output image fade or darken.

 UV Printer

The last thing I know is that the printed PASS is too low.Generally, on objects with small materials, we can use high pass printing, which will make the printed colors full and clear. Print large format patterns and print with a lower pass. Therefore, it can be adjusted according to the pass when printing, so that the printed pattern is not difficult.
Finally, I hope that the print will be carefully handled when using uv inkjet printer, and try not to make some low-level mistakes.

When using uv flatbed inkjet printer,Some tips you should know that

When using a uv flatbed inkjet printer, you may encounter a variety of problems, the following are commonly encountered:
1. When moving the uv flatbed printer, be careful not to carry the printing platform to move. To lift the bottom of the machine, you can use both hands to hold the casing to realize the mobile flatbed printer.

 UV Flatbed Inkjet Printer

2. When using a flatbed printer, many customers say that the USB interface cable is not easy to check. In fact, just fix the USB cable hot melt or connect the USB interface on the motherboard above the head.
3. The way to add ink to the flatbed printer. Generally speaking, there are two types of ink supply methods for flatbed printers. One is a separate ink cartridge and two are continuous ink supply systems. However, the two ink supply systems have a complete set of similar working components, ink cartridges, nozzles, and cleaning units. , ink guide tube, waste ink bottle. In the case of ink refilling or in the case of an ink tube, you can use an ordinary medical syringe to pump air at the bottom of the cartridge until ink enters the syringe, or the ink is drawn from the ink tube on the waste ink bottle.
4. UV flatbed printing machine height adjustment. Generally, flat-panel printers that are popular in the market mainly detect the height of objects by infrared rays. Before the printing instructions are issued, the objects should be placed first. If the surface of the printed items has irregularities, it is necessary to pay attention to adjusting the height of the nozzles and printed products in order to avoid Crashed the nozzle.
5. Eliminate static electricity, generally the current manufacturers have not noticed, in fact, static electricity sometimes causes great damage, you can connect an external wire in the metal case, the external wire can be grounded.

UV Flatbed Printer

6. How to spray the printed product layer, many people report that their coating is not good, to be honest, the coating actually needs a certain technology, when you understand the real use of the coating, it is very simple, so don't Let the salesperson fool you. The role of the coating is to use the ink to image. Therefore, when spraying the layer, just apply a layer or silk screen to the surface of the object. It does not need to be too thick. A good coating is also very good for adhesion. Some manufacturers say that it is better to spray the coating with a thicker adhesion. This is unscientific and increases the cost.
7. The printed picture has streaks. If the printed product has streaks, there are generally 2 possibilities. On the one hand, the 2 items storing the data are dirty. On the one hand, the nozzle may be bumped or the nozzle is blocked.
8. The nozzle drops ink. When this happens, the printed products will be mostly defective. There are two possibilities in this case. One is that the rubber ring of the cleaning unit is not sealed well, and the other is After the nozzle is hit, ink droplets gather at the bottom of the nozzle. In the first case, it is OK to change the rubber seal. In the second case, you need to use a cotton ball to wipe the bottom of the nozzle.
Therefore, the uv printer must be pay attention to daily maintenance,because it is too expensive.

UV flatbed printer-how to clean the nozzle after it is blocked

UV flatbed printer.Because it can print all kinds of pattern and trademarks on the plane of any product, it is suitable for small and medium-sized enterprises to print and print. It is more suitable for entrepreneurs. It is a good helper for entrepreneurship! The most fear is the sprinkler, because it costs thousands of dollars for another one. Ah, our printer is okay, no matter how many colors, it is a nozzle. If the UV machine is troublesome, because the UV machine is how many colors, it is necessary to pay attention to the maintenance and maintenance of the nozzle.

 UV Printer

When we found that the printed content of the UV printer was broken or white, and there was still a lot of ink remaining in the printer's ink cartridge, we must use manual cleaning to remove the ink particles that were jammed at the nozzle. When using the manual method to clean the blocked ink nozzle, we first need to carefully remove the nozzle. When removing the nozzle, pay attention to the structure of each part, and carefully observe whether the nozzle has an integrated circuit part, which is convenient for refilling the nozzle.
In the process of actually using the UV flatbed inkjet printer, many printing users often take the ink cartridge out of the printer cartridge, which makes it easy for the printing nozzle to be severely clogged, and even some of the ink inside the cartridge can dry out. At this time, the printer generally cannot print. In the case of such a phenomenon that the nozzle is severely clogged, we must prepare some alcohol with a concentration of about 95% and a plastic medical syringe, and then use a disposable infusion tube to connect the ink supply port of the print head, and then print the nozzle. The head position is placed in alcohol with a concentration of about 95%, and then the alcohol is sucked into the medical syringe through the printing nozzle, and the clogging ink in the nozzle can be cleaned by repeatedly performing the ink absorbing operation.

 UV Flatbed Printer

Tip: Considering that different ink manufacturers produce different ink compositions, different brands of inks are often mixed and used together, which is prone to chemical reactions and may produce particles that can cause damage to the print heads. Causes the print nozzle to become clogged. Therefore, in order to reduce the number of times the print head is blocked, we try not to change the ink type frequently, so as not to cause damage to the print head. In addition, each time you use the empty ink, you need to reinstall the new ink cartridge; when installing a new ink cartridge, be sure to control the installation force. If you are not willing to press the ink cartridge into the ink cartridge, it is easy to deform the ink cartridge support mechanism. Or shift, which affects the normal spraying of the ink; therefore, when installing a new ink cartridge, try to use the appropriate force to place the ink cartridge into the ink cartridge support mechanism as prompted by the universal printer operating instructions, instead of using brute force to destroy the ink cartridge holder.Borrow the external force and let the blocked nozzle return to normal.

If we find that the printed content of the UV flatbed printing machine is only a faint ink trace, and other printing operations are normal, then the phenomenon that the nozzle of the ink cartridge is blocked is not very serious. When the nozzle is blocked, we can Use the nozzle cleaning program built into the universal printer to restore the blocked nozzle. Generally, most models of inkjet printers have a built-in nozzle cleaning program.

UV Flatbed Printing Machine Coating, Six Methods to Verify That It Is Qualified

When we buy UV flatbed printing machine coatings, we often worry about buying bad quality. Poor quality coatings will not only affect the print quality, but also damage your printer.

1. The adhesion

UV Printer

There are many ways to measure the adhesion, such as 100 grid method. If the printing product quality requirements are high, you can also test the printed product immersion or boiled inkjet screen is off or not. Adhesion is the key to measuring the quality of a UV flatbed printer's coating. High-quality coatings should pass the 100-grid test and should not peel off after soaking or boiling water.

2. The leveling

Leveling is a common paint performance indicators, refers to the ability the coating of UV flatbed printer appears brush marks and spray fogging when paint brushing or spraying on the surface of the object. Poor flatness UV PRINTER coating will affect the decorative effect of the print. More importantly, if the brush marks on the coating surface do not disappear automatically, the uneven coating surface may rub the large format UV printer nozzle, causing significant damage. High-quality coating should be formulated closely, level quickly after brushing or spraying.

3. The transparency of the film

As a high value-added decorative products, UV PRINT appearance requirements are generally high. This requires UV flatbed coating film colorless, transparent. Now on the market there are some epoxy resin-based two-component coatings will be yellowing, which it will affect the decorative effect.

UV Flatbed Printing Machine

4. Weather ability

UV printing products, especially signs, billboards, prints in outdoors must be long-term bright as new, do not fade. Specifically, It requires UV flatbed printer coatings to resist ultraviolet light. Some coatings now yellow under long-term light conditions and are not suitable for outdoor use. Even for UV-printed products that are only used indoors, there is a general need to consider the use of weather-resistant UV plate printer coatings to ensure product quality.

5. The ease of use 

Currently on the market UV coating two-component and multi-component products, relative to the multi-component products, no need to configure the single component UV flatbed inkjet coating in the use of more Big advantage.

6. Product safety

This is a problem that must be considered. Solvent-based coating of UV flatbed inkjet printer is not only smelling, but also caused by the improper storage of security risks, transportation is not convenient. Because of the high investment in UV flatbed inkjet printers, it is best to consider safer aqueous UV coatings when choosing a coating. If solvent-based coatings must be used, it is recommended that they be stored separately from the UV flatbed digital printer to eliminate potential safety issues.

UV Flatbed Printer

According to the above method to judge and buy a good quality coating, this will save you a lot of trouble.
