I have been attempting to fix this issue for several days without success. It's been bugging me but does it really matter?
A nozzle check shows one gap on the cyan, something like this:
--------
--------
---- --- <
--------

I have tried the paper towel/windex solution including waiting over night, multiple head cleans but it remains. Other than bugging me I can't see where it really makes a difference. I printed out several images including a test chart for profiling and I don't see a single gap anywhere. So, other than it bugging me that I can't fix it, should I just try to ignore it?
