How to make the printhead of UV printer like the new?

UV printer printhead maintenance methods are available in four ways, including initial installation, routine maintenance, fault maintenance, and maintenance during the fake period.

After the equipment is installed, the equipment is initially installed to maintain the print head.

In order to get the printer head into optimal operation, before the UV printer officially begins to undertake the production business, please be sure to print some pictures as much as possible in 1-2 days. The picture is best CMYK/LC/LM/W 7 colors. Used, and add color bars on both sides of the screen to ensure that 7 print heads are always in the inkjet state.

How to maintain the print head after the daily work is completed?

In the off state

After all the print jobs are completed every day, in order to keep the print head in optimal working condition and to avoid clogging the printhead due to UV ink evaporation, please follow the method below to maintain the device and let the device stay overnight.
1. Turn off the UV printer power supply.
2. Clean the non-woven fabric with a special cleaning solution, then pour the cleaning solution onto the non-woven fabric to make it wet.
3. Move the handpiece back to the rightmost cleaning station and tightly bond the nozzle to the nonwoven.
4. Keep this state for the device to stay overnight.

Power on

1. Turn off the UV lamp and draw the wind on the platform.
2. Print the test strip, check whether the print head status is intact. If not in good condition, continue to maintain the print head until the print head is in good condition. (no needle, no oblique spray)
3.Do not turn off the computer and software, let the machine standby flash.

After the printhead was found to be slightly blocked, the treatment method was found.

1. Regularly maintain the print head (slightly wipe the print head surface with a non-woven fabric) until the nozzle is in good condition.
2. Cleaning solution maintenance (squeeze the surface of the print head with a sponge stick to the cleaning solution for 1-2 minutes), then wipe the surface of the print head with a non-woven fabric, check the print head status diagram. And repeat the operation several times until printing the head status is normal.
3.Combined with the cleaning solution maintenance method, increase the print head correction voltage 1-2V print 2 m * 1 m color block (print the print head state problem color color block) interval 2-3 times check the printhead state map until the print head status normal.
4. Do not rinse the print head without authorization. If the print head is damaged, the consequences will be at your own risk!printheadAfter the equipment is installed, the equipment is initially installed to maintain the print head.

The UV printer is not used for a long time, and the printer’s print head is easily blocked. Especially during the Spring Festival, the temperature is relatively low, and the ink is prone to deposits and impurities after being frozen. Ensure that the room temperature is between 20 ° C and 30 ° C. If the temperature is too low, it may cause serious damage.

 

Simply adjust the UV printer ink thickness to master these two methods

UV printer

UV printers are becoming more and more popular in the printing market, but it is a new model after all. Many people are not familiar with all-round printers. Recently, there are many customers who can consult whether the UV printer can change the thickness of the ink. What is the detailed method, let us know here today.

Generally speaking, domestic UV printers are usually four colors, and industrial equipment standards are six colors and eight colors. Adjusting the thickness of the ink mainly depends on three factors.

Adjust the ink thickness of uv printer. It can be analyzed from three aspects:

The first is the variety and background color of the raw materials. If the raw material is soft in appearance, the gap is large, and the base color of the raw material is deep, the demand is increased by 20%-40%.

Second, if the image is darker and the color requirements are more beautiful. The thickness of the ink should be appropriately improved.

In the end.Depending on the special request, if you want to emboss 3D, you need to add the thickness of the ink.

To change the thickness of the ink, you can use the method described below:

In the printing software, it is possible to set the percentage of the ink ejection amount. And it is also possible to set the number of printing passes and then change the thickness of the ink. The advantage of this is that on the one hand it saves ink and on the other hand it improves the quality of the print.

The UV printing machine advances to set the thickness of the ink, and an auxiliary function is the percentage of feathering. Usually between 0% and 200%. If the pattern printed by the system becomes more delicate and the color is more abundant. It is required to register the feathering function. The larger the value, the better the printing effect, the same, the lower the production. Speed, the details should be determined according to the actual needs of users.

It should be noted that the thickness of the ink set by the UV printer is not as thick as possible. The same is true if the setting is unreasonable, which will affect the quality of the printed color.

What should I pay attention to when wide format photo printer working in wet environment ?

wide format photo printerWith the arrival of the rainy season, some advertising operators may not pay much attention to the environmental protection of wide format photo printers. The wet environment brought by the rainy season can easily affect the normal operation of wide format photo printer and the quality of printed pictures. Not paying attention to the impact of changes in this environment, sometimes it will delay the effort.

For example, there are a series of problems such as fading and watering. In most cases, we will mistakenly think that this phenomenon occurs because of ink problems. This will bring us great obstacles to solving problems and finding specific reasons.

In a humid environment, the large format inkjet printer can still cause many problems, such as the short-circuiting or even burning of the condensed water droplets on the motherboard and the print head, and the large format inkjet printer printed in such an environment. The ink on the screen is difficult to dry, which makes the work efficiency greatly reduced. This has to be said to be a rather troublesome problem.

wide format photo printerIn the working room where the large-format photo printer is stored, try to ensure that the room is dry, close the doors and windows, prevent the spread of outdoor moisture, and maintain a proper high indoor temperature, and then use a large fan to dry the printed image. The material of large-format photo printers is mainly composed of paper and paper coatings, which are relatively easy to absorb moisture and moisture. When the material is wet, it will cause the ink to spread when printing.

For the materials required for large-format printing machines, they should be protected after use, and placed in a fixed position, remember not to be in direct contact with the ground wall.

How to maintain the eco solvent printer in dry weather?

In fact, the maintenance of eco solvent printer cannot be relaxed all year round. Everyone knows that autumn is a very dry season, and the eco solvent printer’s working environment humidity is between 20% and 80%. Therefore, it is necessary to keep the working environment of the eco solvent printer normal.

eco solvent printer

Here are a few key points for the maintenance of eco-solvent printers in the fall:

1. It is easy to generate static electricity during the dry season, and the large format eco solvent printer is most afraid of static electricity, so be sure to connect the grounding wire;

eco solvent printer2. Keep the floor clean: when the weather is dry, there will be dust, which will affect the life and efficiency of the eco-solvent printer. You can often mop the floor and sprinkle water to keep the room from drying and dust.

3. Ink: It must be used when the ink is loaded. The remaining ink will remain in the vicinity of each time the printhead is sprayed. Frequent printing of new ink will wash away the last remaining ink, otherwise it will slowly solidify, causing the printhead to clog;

eco solvent printer4. Maintain a constant temperature in the room, and the operating environment temperature is between 15 ° C and 30 ° C;

5. The relative humidity of the eco-solvent printer operating room should be kept at 40%-60%.

The problem of flying ink in eco solvent printers is difficult to solve?

In winter, due to the cold and dry climate, eco solvent printers will appear to fly ink and other phenomena, seriously affecting the sound field quality. Here, the author briefly introduces how to choose ink to make the large format inkjet printer work normally in winter.

eco solvent printerFirst of all, in the ink purchase should choose the ink suitable for winter use, domestic manufacturers have corresponding products launched. Another method is to warm the ink supply tank and raise the temperature of the ink. This method uses a large amount of electricity, but it is also worth promoting because it is much safer than adding a bulb at the bottom of the cartridge. The higher viscosity of the ink will damage the piezoelectric ceramic inside the nozzle and cause the fatigue of the nozzle to rise, such as the vertical surface of the painting surface!

eco solvent printerSecondly, we can control the ink activity by controlling the ink temperature. That is, the ink cartridge heating method is to add a temperature control device to the secondary ink cartridge. Some people simply add a light bulb to the bottom of the ink cartridge (if the space agrees) The effect is not bad.

Finally, the eco-solvent printer nozzle is maintained diligently. Ink water is a volatile liquid, the volatilization speed will be accelerated when air drying, and the ink on the surface of eco solvent inkjet printer printhead will dry quickly, resulting in the blockage of the printing head. In the printing process, the phenomenon of flying ink, frequent broken lines and inkjet skew occurs. If we do not pay attention to the maintenance of the printer’s printer head, it may damage the printer head.

If the eco-solvent printer ink is stored in a low temperature environment, its viscosity willincrease a lot, and the activity will be reduced accordingly. The temperature can quickly increase the ink activity but the ink viscosity will not decrease rapidly due to the temperature rise. The characteristics of the winter ink are mainly in the activity (the activity of the ink is much lower due to the lower temperature environment). To test the activity of the ink, there is a very simple way to take a piece of smooth iron. A little ink is then tilted at an angle to observe the speed of the ink on the iron piece.
