Causes of failure of digital printing machine nozzles

Update time : 2021-11-03 11:49:49

The digital printing nozzle can have the best printing effect when it is used normally, and if the nozzle is good, the ink performance will be better. The nozzle is an indispensable core of digital printing production, but if the operation is not good, the nozzle is prone to failure, so do you know the cause of the failure of the nozzle of the digital printing machine?
First of all, ink is a kind of liquid that is easy to evaporate. Therefore, the ink must be volatilized into the air to make the picture dry. Therefore, our common nozzle clogging refers to the nozzle hole clogging outside the nozzle after the ink accumulates to a certain extent.

Cause one of the nozzle failure:
In the process of our daily use, when the nozzles are sprayed onto the medium, a part of the ink will always remain around. After this part of the ink is dried in the air, the nozzles will gradually become smaller and cause the nozzles to be blocked problem.

Cause two of the nozzle failure:
The aging of the electronic components of the drive circuit and the accumulation of too much dry ink dirt may affect the voltage of the drive nozzle, resulting in no ink or unstable ink output from the nozzle.

Cause three of the nozzle failure:
Failure to protect the nozzles when replacing ink will also affect the inkjet status of the nozzles.

Cause four of the nozzle failure:
The use of a long-time nozzle, especially a factory where the printing task is not full and often shut down at night, will cause the ink to stay in the nozzle for too long, and it is easy to adsorb on the internal filter or the wall of the ink channel, causing the ink to flow. The smaller the cross-sectional area will also cause the ink not to come out of the nozzle.

Next are some tips on how to maintain the nozzles:
Static electricity and dust can damage the nozzles. If the static electricity is too high, it will easily damage the nozzles or circuit. Dust can easily clog the nozzles and cause the printed image to break. Therefore, the printing speed must be controlled to prevent excessive static electricity.

Too low temperature will also change the viscosity of the ink, especially for low-quality inks. In winter, the viscosity of the ink will increase, which will block the nozzles and cause oblique spraying and ink breakage, which will affect the life of the nozzles. Therefore, users should choose inks with good weather resistance and good quality when purchasing inks. Subtextile has always been committed to providing customers with high-quality sublimation printing consumables, of course, including sublimation ink. Our ink has extremely high fluency and strong color expression, suitable for most of the sublimation printers on the market.
