PIXMA iP7220 printing pattern of blurry and clear lines

When printed from Notepad the lines look like this:

As you can see it's printing blurry and clear in a pattern, about 5 lines blurry, 2-3 lines clear, 5 lines blurry, etc.

I've run all typical fixes: cleaning, deep cleaning, print head alignment, plate cleaning, roller cleaning, replaced all ink carts, and then removed all the ink carts, swabbed everything down and put them in again.

Any ideas would be appreciated, I'm at a loss. Machine is roughly 3 years old and has been inactive for about year, thinking maybe the printing head might be dead?
