Deep Cleaning does not unblock inkheads for the group 2 inks, M, Y, PM, R, and the GY for Group 1. What can I do to unblock them?

Since Deep cleanings have not cleared the blockage you either have a printhead failure or an electrical problem in the printer.

You have nothing to lose by trying some of the printhead cleaning processes you can find on YouTube.

I did go to youtube and found the 50% isopropyl-50% water soak of the printhead worked after, apparently the dried ink was removed. I did the 1/2 inch soak 3 times, waited for it to completely dry, replaced cartridges and bingo.....print perfect.
