What behavior is easy to harm the uv nozzle?

   The nozzle, the core component of uv flat-panel printer, can extend its service life

if used and maintained correctly. However, due to some incorrect operations,

the service life of the nozzle will be greatly reduced. After a long time of experience

accumulation, summed up the behavior that is most likely to harm the nozzle.

1. Do not cut off the power when disassembling the nozzle. Install and disassemble

the circuit of uv printer without turning off the power switch and cutting off the

main power supply. This behavior will damage the service life of each system,

especially the nozzle.

2. Leave the cleaning fluid in the nozzle for more than 48 hours. Soaking the nozzle

with cleaning solution for a long time can remove stains more effectively. However,

if the soaking time exceeds 48 hours, it may cause corrosion to the nozzle orifice.

3. Change the ink without cleaning. Even for the same ink, the components of

the ink produced by different manufacturers are different. If the ink is changed

directly without cleaning, it may produce more particles and block the nozzle,

or the two types of ink with different structures react, so the nozzle must be

cleaned before changing the ink.

4. Use substandard ink and cleaning fluid. The ink with poor quality will affect

the printing effect and block the nozzle, and the cleaning solution with poor

quality may also corrode the nozzle. Do not choose the cheap ink and cleaning

solution with poor quality for small gain. It is better to choose the ink specified by

the equipment manufacturer, otherwise the equipment manufacturer may

not guarantee the equipment.

5. Clean the nozzle vigorously with high-pressure air gun. Cleaning the nozzle is

a meticulous work. It is not allowed to directly wash the nozzle with a high-pressure

air gun for the sake of speed. If the nozzle is only slightly blocked, it can be gently

flushed with a needle tube, and an appropriate amount of cleaning fluid can

also be added to the needle tube to clean the nozzle.
