What should we do if we don’t use the UV printer often? This situation is inevitable, especially during the Spring Festival holiday. The short is 10 days, 8 days, and the length is 20 days. The printing company does not start work for one month. Protecting the UV printer system during this period will bring very serious results.
1. Head is invalid
For a long time (more than 5 days), if the nozzle is not pressed or wet, the residual UV ink in the nozzle will solidify and dry, which will directly cause internal blockage of the head. In this kind of damage, cleaning the head again is useless and needs to be replaced.
2. The ink system is blocked
If the ultraviolet ink in the ink tube, secondary ink cartridge, and large ink cartridge is not used for a long time, it will inevitably lead to precipitation and condensation. If it is reused, it needs to be replaced with a new one.
So, what if you don’t use it for a long time? There are two common solutions.
A. Remove the head
After removing the head from the equipment, clean the UV ink in the head with cleaning liquid, then immerse the bottom of the head in the cleaning liquid and wrap it with non-woven fabric, then wrap it with plastic wrap 10 times and put it in the cabinet. Remember not to put it in the sun or in a humid place.
B. Remove the ink tube
Take off the ink tube and discard it directly. Clean the secondary ink cartridge, draw out the UV ink stored in the large ink cartridge, and put it in the UV ink bottle again.
