What to do if the uv printer is not used for a long time?
It is inevitable that the UV printer will not be used for a long time, especially when the Spring Festival holiday is encountered, as short as 10 days, 8 days, and as long as 20 days. The printing company will not start for one month. Uv printer system maintenance will bring very serious consequences.
1. Scrap of nozzle
For a long time (greater than 5 days), if the inkjet head is not inked or moisturized, the UV ink remaining inside the inkjet head is solidified and dried, which directly causes the inside of the nozzle hole to be blocked. Under such damage, cleaning the spray head is useless and needs to be replaced again.
2, the ink system is blocked
If the UV ink in the ink tubes, secondary ink cartridges and large ink cartridges are not used for a long time, it will inevitably lead to precipitation and condensation. If they are used again, they need to be replaced with new ones.
So, what should I do if I don't use it for a long time? There are two common solutions.
A. Disassembly of the nozzle
After removing the nozzle from the device, clean the UV ink inside the nozzle with a cleaning solution, then dipped the cleaning solution with a non-woven cloth, wrap the bottom of the nozzle, and wrap it with plastic wrap for 10 or more turns and put it in the cabinet. . Remember not to place it in a place where it is exposed to sunlight, or in a humid place.
B. Remove the ink tube
Remove the ink tube and throw it away. Clean the secondary ink cartridge, and then remove the UV ink stored in the large ink cartridge and put it back into the UV ink bottle.
In addition to the above methods, it is also necessary to cover the surface of the UV printer equipment with a layer of cloth to avoid accumulation of dust for a long time, which causes rust and abrasion of the screw rods and guide rails. It can be cleaned once in advance at the position of core parts and wipe the lubricant.
After the holiday is over, if the print head and ink system are reinstalled, the UV printer can be used normally.
