For what possible reason cyan ink wont work

[jcalp]

Hello,

Im working on my epson 1430W with uv ink, printhead is in good working order, nozzle check print out good no missing lines.. i printed a test page with CMYK Colors on it, Black, Yellow, Magenta works great but cyan just show some lines and sparkled ink particles, what could possibly be the problem?

PS: Using Acrorip as a RIP software

Dampers, catridges might gone bad or your head is not sitting properly on cap if everything else is fine.

How do i verify the head is sitting or not properly on the cap?

You should get a good result. Maybe your ink might have gone bad too.
