Why PrintHead Easily Damaged And How To Solve ?

Printhead is the most important part as for a inkjet printer ,also is easlier damaged part .The reasons of printhead damaged have so much ,like printhead quality ,inkjet printer quality ,daily use and etc .This blog will show you on ink aspect .


1  the ink viscosity is too high
If the ink viscosity is too high will cause the ink  tube adhesion, resulting in insufficient ink supply. The ink volume will be not enough and also cause the color fault. Especially in the winter, the temperature is low, this phenomenon is more prominent.
Solution: To improve the indoor temperature (such as air conditioning, with a dryer, electric heaters, etc.), so that ink viscosity. Or use a more viscous ink.

2 The Pressure on The Nozzle
The voltage of the nozzle, because the level of the nozzle can determine the level of the internal pressure of the piezoelectric ceramic bending, and thus high voltage can also increase the amount of inkjet. Does not affect the quality of the picture under the premise of the lower the better.
Different Situation
A. The nozzle voltage is high and the ink viscosity is low, it will cause too much inkjet, the speed is too fast, the ink point reflects the bottom of the nozzle to form ink droplets plug the nozzle, there will be burr and floating phenomenon.
B. If the nozzle voltage is low and the ink viscosity is high, there will be no ink spray, color block is not uniform, not full and so on.
Solution: Replace the appropriate ink or lower the voltage

3 Ink Viscosity is Too Low
If the ink viscosity is too low, the ink is too thin, inkjet speed, ink sprayed on the light cloth will be reflected back to the nozzle, causing the ink stagnation in the nozzle, causing nozzle clogging. Long time spray the same color. This phenomenon is more prominent.
Solution: Spray the nozzle with a professional swab sticky cleaning solution. If you want to completely solve this question will have to change the viscosity of high ink.


4 The Impact of Static Electricity on Equipment And Ink
 In the inkjet process due to the inkjet substrate and the roller friction produced a lot of static electricity, if not promptly ruled out, can easily affect the normal operation of the nozzle, such as ink droplets enough to be affected by static and deviate from the trajectory of the screen And if the static electricity is too large may also damage the nozzle, and the computer equipment under the influence of high static electricity prone to garbled and crash phenomenon, or even burn the machine circuit board phenomenon
Solution:Take the correct and effective measures to exclude equipment Of the static is extremely important. Buried ground is a good way to eliminate static electricity.

The following are four important aspects ,and if you also have problem about printhead ,please read this blog clearly ,hope can help you ! What is more ,you can share this blog to your friends who work for digital printing ,it may help him or her .
