What You Do Wrong For Maintaining Nozzle?

Inkjet printer inkjet quality and poor, which is mainly reflected in the focus on the piezoelectric nozzle, such as the common nozzle plug, broken and serious damage to the nozzle will affect the pictorial inkjet print normal output.

In the use of inkjet printers, nozzle maintenance more need for our careful treatment, especially for novice users, the nozzle maintenance, more or less there will be some wrong way, especially some improper operation of the nozzle maintenance, It is likely to directly damage the nozzle, or cause more serious consequences. The nozzle is the core part of the inkjet printing equipment, if the correct use and maintenance, can greatly extend the life, but because of some incorrect operation, then accelerated the nozzle loss. Shenzhen Wuteng photo machine manufacturers summed up some of the wrong way on the maintenance of the nozzle, I hope that customers in the daily maintenance operations to avoid these common mistakes, so that the useful life of the nozzle for your inkjet printing business to obtain a better profit return


The following several nozzle operation is most likely to damage the behavior of the nozzle, you have a few?
1: inkjet printer maintenance disassembly nozzle without power.
In the case of power is not completely shut down, free to install or remove the pictorial circuit, this wrong way to easily lead to the relevant circuit short circuit, especially the nozzle, more likely to cause damage to the nozzle, so this operation must pay attention to broken Electricity after the operation.

2: do not pay attention to electrostatic protection
Piezo photo machine normal inkjet printing work by electrostatic impact, so in the nozzle maintenance operation do not hand contact with the nozzle, maintenance nozzle to wear protective gloves, you must always check the ground connection.

3: do not regulate the location of the nozzle
When using the external force to adjust the nozzle position, whether it is to replace or fine-tune the nozzle, do not use brute force, please follow the norms carefully treat the nozzle.

4: Use inferior ink
The use of low-quality ink and free replacement of different batches of ink and ink suppliers, low-quality ink will not only affect the color and quality of print patterns, but also damage to the picture machine nozzle, serious may also cause nozzle clogging and other irreversible Loss, it is recommended that users must choose the original ink manufacturers or manufacturers recommend ink, this is very important, do not seek cheap and cause large operations, due to small and lost.

 5: improper use of cleaning fluid
In the Wuteng photo machine site content, also shared the relevant cleaning fluid immersion nozzle use operation, nozzle maintenance article, we have said that the nozzle soaked in the cleaning solution 1 to 2 hours. Cleaning the solution for a long time is conducive to clear stains, but if the nozzle in the cleaning solution soak for more than 2 days, there will be negative effects, as we soak the nozzle of the longest time should not exceed 30 hours. In addition, the entire nozzle placed in the cleaning solution soaked, this way is not desirable. As the nozzle there are many electronic components, and cleaning fluid are mostly corrosive, so when you must soak the soak, can only soak the spray on the site, or directly take the right amount of cleaning fluid into the nozzle cleaning, In the cleaning nozzle should pay attention to the circuit board and other exposed electronic components do waterproof treatment.

6: frequent cleaning nozzle operation.
Frequent cleaning nozzle is also an inappropriate behavior, on the one hand the waste of the larger ink, on the other hand the nozzle will also have a certain impact. Sprinkler cleaning frequency is generally recommended once a month thoroughly cleaned, in the usual use of the software in the "automatic cleaning" function can be.

Some of the common mistakes mentioned above, will be easy to bring bad damage to the nozzle, these pictures of the wrong way to maintain the nozzle, you a few bars? If the operation exists, please correct it.

Do You Know Why Your Printhead Always Block?

Inkjet printer are an important device for digital printing today, and various types of inkjet printers appear to meet different types of digital printing. Inkjet printers with low print speed, such as: Oric inkjet printers; printers with high print speed, such as: Epson inkjet printers; inkjet printers with wide print widths, such as: Roland inkjet printers


Inkjet printers appear in different models, greatly expanding the scope of application of inkjet printers. Large to outdoor banners, textiles and clothing, metal materials, small pillows, mobile phone shell, mug, etc. small gift industry, you can use inkjet printers to print, the application of a wide range.


Printhead is one of the most important parts of inkjet printers, printhead is good or bad, whether the normal use, directly related to the normal use of inkjet printers. Some inkjet printer printhead is particularly easy to plug, inkjet printer printhead why plug? Inkjet when the machine's printhead does not produce ink, resulting in lack of color content screen, usually called "nozzle plug", is the impact of picture quality and yield of the main factors. Of course, "plug" is also a variety of reasons, generally have the following circumstances:


1, the ink in the printhead to a certain extent after the outside of the printhead hole is blocked: the most common way of plugging, because the ink must be volatile in the air to the air in order to make the screen dry, so the ink is a volatile liquid, in the The air is volatile and clears solid. When the ink is sprayed on the fabric, it will always leave a portion of the ink around it. This part of the ink will dry slowly in the air to make the nozzle smaller or even block the printhead, but because it is outside the printhead, it is easy Clean up, which is why we often clean the printhead of the reasons.

2, the piezoelectric crystal damage: sure that the printhead can not spray ink, the general piezoelectric printhead can be used for a year or so, in the inkjet workload of many factories may also use less than a year is normal.

3, the piezoelectric crystal fatigue damage: the phenomenon is sometimes spray printhead inkjet, and sometimes spray the ink, especially in the large amount of inkjet (that is, when the dark screen) "jam" phenomenon is obvious, the best way is to replace a new printhead.

4, the printhead inside the filter blockage caused by the printhead no ink: the use of a longer time the printhead, especially in the inkjet task is not full stop at night the factory, the ink does not flow in the nozzle for a long time, easy to adsorb in the internal filter Mesh or ink on the wall, so that the flow of ink cross-sectional area will also cause the printhead no ink phenomenon, and now dedicated equipment can help you solve this problem.

5, the viscosity of the ink is too high or too low: the viscosity of the ink is too high to make the ink flow is poor, the amount of ink sprayed per unit of ink is not enough; ink viscosity is too low, that is too thin, easy in the nozzle pressure When the transistor pumped in the air, can not absorb the ink, which is sprayed out of the air; both will cause the printhead no ink phenomenon. It is important to ask the customer to store the ink environment, and it should be better to use the ink for more than 24 hours before using the ink because the ink will have a high viscosity at low temperatures and the viscosity at high temperatures Becomes very low, this viscosity is very different, once the viscosity difference between the larger ink mixed together, it will cause the phenomenon of ink can not spray.

6, the drive circuit failure: the drive circuit of the electronic device aging and accumulation of too much dry ink dirt, may affect the drive printhead voltage, causing the printhead no ink or ink instability.

7, the type of ink: some manufacturers of ink due to improper control of the amount of desiccant, dry too fast, easy to cause the ink in the external blockage, although you can clean, but the cleaning time interval is more frequent, once a long time without the nozzle and not timely When the printhead is protected, it may cause permanent damage to the printhead at the next time.

8, frequent replacement of ink: the replacement of ink in many cases may not protect the printhead, but also affect the printhead inkjet state.

9, the machine uses the ambient temperature and humidity: the general recommended temperature of 22 to 25 degrees, humidity 40 ~ 70%, high and low temperature affect the viscosity of the ink, the nozzle will produce ink phenomenon or paste the phenomenon, often mistaken Think of "printhead clogging".

So in daily use, regular and reasonable cleaning and maintenance of the printhead is necessary, if you have no way to understand, please feel free to consult us.
