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.
The failure was caused by the blockage of the black ink tube and the ink outlet;
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?
The compatibility of UV ink and varnish has caused problems.
Generally, if the quality of the two is no problem, the UV ink can be replaced with a soft one, which can solve the problem of reacting with the varnish.
