Hi guys,

I have a chinese UV printer using Epson 1390 print head.
The printer printed fine for a month but then suddenly the magenta is coming out in a different colour with strange lines.
I did a nozzle check and it seems like the magenta nozzle is clogged?
Please see photos. It is using CMWWKY (sorry but hard to see on the photo)
First 2 images are done after manual head cleaning.
Some lines are missing on all nozzles, but its fine for me, main problem is the magenta not printing magenta.

I then thought it might be the problem with the print head, so I went and bought a new replacement and today I added it on did some automatic head cleaning using software and did a nozzle check, see the last image, the magenta nozzle came out cyan for some reason.
Seems like it is not the print head problem, anyone know what the problem might be? Could it be the ink bag or tube?

Hope someone can help me here.
Thanks

I think you should contact the printer supplier wtih this problem, you probably got some cleaning/purge/maintenance instructions from them for the special handling for these UV inks + a cleaner whatever.
