How to maintain the life of the Epson nozzle of the UV printer
1. Use certified inks, use word-of-mouth inks used by others, use inks from major manufacturers, and use versatile inks. In the current industry situation, most inks are not very different.
2. The feng shui problem placed by the machine, the temperature is kept at about 20-25 ℃, and the ink that is more than 30 ℃ is easy to agglomerate and jelly. It is easy to cause clogging. The evaporation of the ink at the nozzle will dry up faster! Try to increase the humidity as much as possible, the humidity should be above 40! The humidity should be above 40, and the nozzle is easy to dry out in an excessively dry environment.
Temperature and humidity are a cause of plugging!
The second reason is light:
UV ink curing is basic common sense when exposed to light. The nozzle is exposed to strong light, and the ink tube is also exposed to strong light. He can cause the ink to dry up, so the machine should not be placed at the door and the sun. It is best not to let sunlight enter the room of the printing studio or the printing equipment, and it is best to rely on the natural lighting in the room of the room, so that it is not easy to cause blocking.
The third reason: the wind and the air flow are too strong. Many people do not install air conditioners in the summer workshop. Instead, they install a large fan on the window to vigorously extract the air. The air flow too fast causes the nozzle to dry quickly because of the wind. The ink solvent Volatile will dry quickly and easily block!
The fourth reason: the environment is very dusty and dusty. The dusty dust will enter the ink, adhere to the nozzle, enter the ink bottle, and block the head!
The fifth reason: the temperature in winter is too low, which leads to the increase of the viscosity of the ink, the smoothness of the ink is weakened, the printing does not come out, or the ink is cut off!
The sixth reason: if the negative pressure device is not installed, the ink level of the positive pressure ink bag is too low, and the ink level is required to be more than 20 cm above the nozzle! The requirement for using negative pressure ink sacs is about 20 cm below the nozzle! If the negative pressure system is installed, the negative pressure is too large, it is easy to lack ink supply, and it is easy to draw and break the ink! The negative pressure is too small, easy to drip ink, easy to accumulate ink and easy to break ink!
3. About the protection of the print head in the stop state.
If there is an ink pad, sit on the ink pad and keep it tightly sealed. The lower pipe is not breathable, that is, the nozzle part does not get air or light!
If no ink pad is used, you can use cleaning liquid or alcohol on the non-woven fabric, sit on the nozzle to moisturize, and check it every other day to prevent it from drying out.
No bubble nozzles! No bubble nozzles! No bubble nozzles! Bubble sprinkler for a long time will destroy the sprinkler! ! ! This is experience! ! !
4. Check the status of the nozzle every day and find that the nozzle is clogged. Immediately clean it quickly. Do not stick to printing in the same situation. Clean the nozzle. Ink pumping cannot be vigorously carried out. The bottom of the nozzle is very coquettish. Extremely huge, easy to cause ink jets! Many sprinklers are not bad, more than half of the sprinklers are bad!
The correct ink extraction method can ensure that the life of the nozzle is extended several times! A simple example of manual ink extraction. After the ink pad is sealed on the nozzle, there is some air in the syringe. Pull gently and slowly. When you see ink drops slowly enter the syringe. Now, let it rest for one minute. After you relax naturally, remove the ink pad, wipe the nozzles, and let the machine flash for half a minute, then you can print! ! !
Many customers encounter plugs, and the ink is pumped out from tube to tube, resulting in worse and worse pump nozzles!
It's not that you can pump the nozzle well if you pump too much. If you pump too much, it will only cut the ink, block the head, or scrap the nozzle! ! !
5. To summarize, several important points about the protection of the nozzle: ink, temperature, humidity, wind, light, correct ink extraction, and correct sealing of the nozzle! As long as these key points are achieved, there is no problem with the life of the nozzle for more than one year! Failure to do so, it is very normal to break down in a few days! Do n’t complain if it breaks, it ’s useless! You can buy the equipment for money, but it is normal for you to not buy the broken technology! This breaking experience is at least an absolute dry goods summed up by tens of millions of worth of bad nozzles! ! ! You can also try to sum up with thousands or tens of thousands of blocks! ! !
6. Special circumstances: vigorously flushing the nozzle will cause great damage to the nozzle, not a dead horse as a live horse doctor. Do not use this method! Flushing the spray head should be done by a professional, and it takes a bit of groping for yourself! Try to be as light, fast, and short as possible, in milliseconds! Hard to hold back for half a minute will hold back thousands of bad, do not believe you can buy a try! ! !
7. Special case two: Be careful when operating and printing. Check the height of the print head every time you print. What is automatic detection and automatic height measurement are useless. The most useful thing is to check before starting. Let the nozzle of the print head hit the printed object without checking The speed of the scrap nozzle is relatively fast, you can try it. When you try it yourself, buy the nozzle and try it. Do n’t use free ones. ! !
8. Special case 3: Drop ink onto the nozzle line, and then drop more, and it can also flow into the circuit. Ha ha, it will be burned directly, no matter how unwilling, how sad, or how you say you are intentional It ’s not deliberate or deliberate, as long as it is powered on, it must be burned! The machine will not discuss with people, water will make you short circuit! Find out before powering on, blow dry, dry, change the cable, don't heartache cable, heartache cable you must burn the nozzle! To exclude everything that can short the nozzle circuit! Do things carefully and carefully!
9. Remember: No white flowers can be thrown away! If you have a lot of money, you can throw it by destroying the nozzle, which will be faster! If you don't want to throw away the white flowers and silver, please operate your nozzle and machine carefully and carefully according to the above eight items! I wish you all wishes come true! ! !
