cross contamination

[asd]

hello everybody, I have this roland sp300v and lately I noticed cross contamination on my test prints, I replaced the dampers, caps and wipers, but nothing seems to help, my question is what will causes cross contamination just the other day I took the covers around the dampers and head and saw magenta going up into my yellow line not just the damper but going into the ink line, the images show the test print before file gets printed and test print after the file was printed and I am getting black into the cyan any help is greatly appreciated

New cartridge

This happens somethimes, when ink in running low. Change the cartridge, 1-2 powerful cleaning and problem solved. Hope this helps!

The lines running from your capping station to the waste bottle might also be clogged. I have seen this happen and cause this problem.
