90% of people don’t know how to clean the print head of uv flatbed printer

The core component of the UV flatbed printer is the print head. Regarding the correct and effective UV printer nozzle cleaning, many customers and friends are not very clear or the method is not appropriate. Below I will analyze the correct method of UV printer print head cleaning, hoping to help customers and friends!

Uv flatbed printer 7 points by maintenance, 3 points by quality.

Cleaning the uv flatbed printer printhead is an important technical activity in the maintenance of the uv flatbed printer. Correctly mastering the cleaning method of the sprinkler can well maintain the printer nozzle, effectively extend the service life of the sprinkler, and reduce the depreciation cost of the device. So how do you clean the printer nozzle, what should you pay attention to during the cleaning process?

Preparation: The rear of the printhead nozzle of the uv flatbed printer also includes the nozzle drive circuit board, so it is necessary to protect the drive circuit board and wrap the rear half of the warehouse with the usual plastic wrap.

There are several ways to clean the print heads of a printer print head:

The first method: immersion method

Scope of application: lighter resistance

Essential tools: 95% alcohol, a clean cup and a flat metal container.

Prepare a small flat plate, place the spray head flat on the plate, and then inject the special cleaning solution for the uv printer into the plate, the depth of which is just immersed in the nozzle. Be careful not to spill water on the cable plug and drive board. The first soak time is about 1 to 4 hours.

The second method: print head injection flushing

Scope of application: The situation is blocked.

Essential tools: 95% alcohol, a clean cup, a disposable syringe, disposable infusion set.

Working principle: Using the pressure generated by the siphon action of the syringe, the organic solvent of alcohol is injected into the print head to clean the dry ink head.

Use a plastic tube of a disposable infusion set, insert one end into the 5ml syringe, insert the other end into the ink inlet of the nozzle that needs to be flushed, and press the distilled water in the syringe into the nozzle, paying attention to the pressure is not too large, so as not to squeeze the water. Waterproof isolating glue inside the bad nozzle. 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 method: distilled water cleaning

Scope of application: severely blocked

Essential tools: a decoded empty cartridge, a disposable syringe, and a bottle of medical distilled water (also available in clean water).

Working principle: It is similar to the working principle of pressure cleaning method, and will not be described here.

Solution: Prepare a decoded empty ink cartridge, a disposable syringe and a bottle of medical distilled water. Using the pressure generated by the siphon action of the syringe, inject the syringe into the distilled water through the vent hole of the ink cartridge, and then inject it into the cartridge for a while. The injected distilled water is sucked out by a syringe, so that the remaining ink in the ink cartridge is washed repeatedly several times.

The fourth method: ultrasonic instrument cleaning

Scope of application: the most severely blocked

Working principle: The ultrasonic cleaning machine generates strong ultrasonic waves to make the water molecules vibrate violently, and the fine dry ink particles are shattered and dissolved in water to achieve the purpose of cleaning.

Solution: Put the inkjet print head gently into the washing machine, add pure water or special print head cleaning solution, pure water or special print head cleaning solution is just enough to cover the stainless steel edge of the print head (be careful not to let the pcb board Contact with pure water or special cleaning solution), and clean it quickly after 10 to 15 hours. The advantage is that the cleaning effect is very good, the print head that has been blocked for many years can be cleaned and the operation is very simple; the disadvantage is that the maintenance cost is high and the price is relatively expensive. Under normal circumstances, ultrasonic cleaning machines can be found in hospitals, eyewear stores or mobile phone special maintenance points, and some places are free, and can also be modified with ultrasonic humidifiers. It is worth noting that the cleaning solution must use pure water or special print head cleaning solution. It is not allowed to use the cleaning solution of the hospital, eyeglass store or mobile phone special maintenance point, because the cleaning solution of the glasses store generally contains more impurities, the hospital The cleaning solution of the mobile phone special maintenance point is generally a strong organic solvent, and frequent use can cause fatal damage that is difficult to repair the inkjet print head.

The fifth method: If the operation has not cleaned the print head, it is basically a hard blockage. At this time, it is recommended to contact the manufacturer and use the manufacturer’s equipment for cleaning.

1). In order to make the nozzle enter the best working condition, please use the 1-2 days to print some pictures as much as possible before the equipment officially begins to undertake the production business. The picture is best used in CMYK 4 colors, and in the picture. Both sides of the C, M, Y, and K color bars are added to ensure that the four nozzles are always in the inkjet state, just like the car just bought back, the better the wear-in, the smoother the machine will be used later. .

2). It is best to take out the moisturizing sponge in the rightmost cleaning station together with its bracket when printing.

2. How to maintain the printer head after the daily work is completed

After all the print jobs are completed every day, in order to keep the nozzles in optimal working condition and to avoid clogging the nozzles due to solvent evaporation, please use the following methods to maintain the equipment for the night.

10. Turn off the power to the device.

2). Clean the moisturizing sponge with a special cleaning solution, then pour the cleaning solution onto the sponge to soak it.

3). Move the handpiece back to the rightmost cleaning station and tightly bond the nozzle to the moisturizing sponge.

4). Keep this state for the device to stay overnight.

3. The treatment method after finding that the nozzle is slightly blocked

1). Recommendation: After the printer head is found to have a slight clogging phenomenon, press the PAUSE button to pause the printing operation without any hesitation. Then use a vacuum cleaner or a manual air pump to spray the ink from the printhead to clean the printhead. After cleaning, it must be squeezed with plastic. The pressure bottle sprays some cleaning liquid onto the nozzle surface to wash away the residual ink.

Note: Do not use excessive force when using the manual air pump, otherwise the print head will be damaged due to excessive pressure.

2. Timely and decisively and thoroughly handling the slight clogging of the nozzle is very important to keep the nozzle in optimal working condition during long printing!

3. In addition, it is also necessary to carefully check the condition of the nozzle and find out why the printing head is clogged.

4. Treatment method when nozzle clogging frequently occurs during the printing process

1. Press the PAUSE button to pause the inkjet job, then press the PURGE button to move the nose to the leftmost cleaning position.

2. Keep the power of the device on, and unplug the liquid level sensor signal line that connects the sub-tank to the head control board.

3. Unplug the ink supply tube (from the secondary ink tank) on the nozzle, and then use a glass syringe to extract the special cleaning solution to clean the nozzle. Method: Use 40ml of cleaning solution every 10 minutes, every 3 to 4 times. .

Why is the price of the uv printer head so expensive?

It is well known that UV printers are expensive, and the print head is the core part of the UV flatbed printer, and its price is also high. Whether it is a new user or an old user, the first reaction to the printhead is “cheap”, so why is the price of the UV printer head so expensive? What factors are causing it?

Technical monopoly
The technology of the print head has been monopolized by the United Kingdom and Japan, and the corresponding technology has been patented. So far, there is no technical strength in China to develop and produce print heads for UV printers, resulting in no market bargaining power, and can only actively accept the price offered by the other party.

UV printer agent
If the UV printer nozzle manufacturer develops the market in China and needs a lot of manpower, material resources and financial resources, it is necessary to choose a company with relatively small domestic influence as its agent. But the agent can never work in white, so you need to insert the corresponding cost when you proxy the print head.

Manufacturers earn profits
Many manufacturers will add a certain fee to the printer head, which is beyond doubt. Few manufacturers will pay for the final door-to-door maintenance costs for the nozzles they sell.

Pay taxes
1. Customs must pay customs duties.
2. Logistics, warehousing and other expenses.

7 common sense about the print head of UV flatbed printer

The print head of the UV printer is believed to be one of the most concerned issues for all users, and it is also a question that is repeated and repeated. After all, the print head is the most frequently used in daily use, and the most common problem occurs around the print head. Understanding the common sense of the print head can help us become more comprehensive and professional.

print head

Import and domestic

The domestic uv printer print head, whether it is Epson print head, Seiko print head, or Konica print head, Ricoh print head and other print heads, are imported, and 90% of them are imported into Japan, and the rest are from the United Kingdom and the United States. Since the country does not have the corresponding technology for the time being, it cannot be produced.

Civil and industrial

print headThe print head of the UV printer itself is not divided into civilian and industrial, but there are big differences in the printing results, printing speed, printing performance and other parameters of different print heads. In order to facilitate the user’s understanding, the industry will divide the high-performance, long-life, and compatible print heads into the industrial field. In contrast, short printheads, high failure rates, and inexpensive printheads are classified as civilian printheads.

Cheap and expensive

To believe that “a penny and a share of goods” is the eternal truth, any product sold by a business is to make money, it is impossible not to make money, or even to sell at a loss. In the same way, there are no good, cheap nozzles, only good and expensive nozzles. Don’t be deceived by the slogan of advertising, you must make a rational judgment.

Print head and technology

Under normal circumstances, the more expensive a printhead is, the higher the capital, manpower, and material resources of the corresponding motherboard program development and upgrade services. Therefore, this has become an important criterion for judging the technical level of the manufacturer. The technical gap between the manufacturers can be compared by asking the price of the nozzles made by the manufacturer.

Print head and ink

Different uv printer nozzles have different nozzle diameters, nozzle materials, and internal structures, so it is important to remember that inks cannot be mixed. Otherwise, it will not only cause a reaction between the inks, but also shorten the life of the printer head, causing it to be clogged.

Encrypted and not encrypted

print headEncrypted and unencrypted printheads primarily refer to the Epson DX7 printhead, which has an encrypted printhead, a secondary encrypted printhead, three encrypted printheads, and an unencrypted printhead. Encryption means that the printhead will print a certain distance after printing, and a color bar will appear, causing the pattern to be scrapped. Unencrypted printheads don’t have this problem, but the price is more expensive than encryption. Domestic uv printer manufacturers are more mature in the process of decoding one encryption and secondary encryption, but the three-encrypted print head is still being cracked.

Warranty and no warranty

This is the last one, mainly because the users who ask too many questions ask and care about it. Once the printing head has been shipped from the factory, it will be returned for sale and replacement unless it is problematic before it is used. Installed on the equipment, after the ink is tested, the problem is that it is not guaranteed. There are too many main uncontrollable factors.

From this point of view, in fact, the printer print head is not without warranty, it is part of the consumables. Why do you often hear that some manufacturers advertise printheads for 1 year or even 2 years? These are just slogans for propaganda. Carefully review the terms of the warranty, various additional conditions, additional costs, harsh to say not to report for 1 year, 20 years of insurance are manufacturers to make money.
