User questions:
This morning, the black ink cartridge of the high-speed cylindrical bottle UV printer does not draw ink, the red light is on, and the negative pressure is abnormal. What should I do?
There is still a lot of material to be processed. Micolorprint technicians are here to help me.
Reason:
The failure was caused by the blockage of the black ink tube and the ink outlet.
Solution:
Block the tube above the large black ink cartridge, replace the ink tube, and replace the ink extraction port to solve the problem of no ink extraction.
There is also a question: if the first time the UV ink reacts with the varnish, how to solve this?
Reason:
The compatibility of UV ink and varnish has caused problems.
Solution:
Generally, if the quality of the two is not a problem, the UV ink can be replaced with a soft one, which can solve the problem of reacting with the varnish.
