I had the 4880 down for about 6 weeks while I was away. 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. The nozzle check look normal with no missing nozzles.
What do you think is going on? Are the dampers shot or is it the head gone? Suggestions.
I’m on a Mac running High Sierra 10-13-1 and using the Print Tool.
