Funky printout of ink separation page

I had the 4880 printer [/img]down for about 6 weeks. I had run a power cleaning twice with Piezo flush before shutting down. When reactivated the printer with K7 inks and 2 power flushes, I printed the ink separation page and got funky results. I make several prints of previously printed picture and they looked the same as does the attached linearization test sheet.
What do you think is going on? Are the dampers shot or is it the head gone? Suggestions.
I’m on a Mac running last software (12.13.1) and using the Print Tool.
Two images attached.
