P6000 head / nossle issue

After having issues with the LK, I removed the head, back / suction the nossles, the printer started up fine, and printed some cleanish checks (still with LK issues). After doing a few head cleanings and one heavy it started printing the attached checks.
I’ve been trying to work my way up with affordable fixes before investing in a new head.
Considering the cost of a new head, I want to make sure that the consensus is that the head is the fix.
Any insight is much appreciated!

sorry for the bad news

Hi Walker,
Thanks for the info.
Do you happen to know what’s causing the yellowish green banding ok the checks?

It’s all coming apart . . . delamination.
