Moust air acumulates in CO cart.
If i cant take it out i use siringe and pull out all ink and foam.Then i rotate al and i push back only ink.When it comes to foam i do stop and drim what is need to be full.

I seldom had problems with air when I refill by dripping.
In a "good" cart it is very fast.
 
so you refil whit seringe now?
 
i dont now......... if is the ink or air. The problem persist.
After cleaning is ok .Second nozzle check again show missed nozzle.
If not printing some days all lines are gone.

Maybe not related to this case, but I had also clog problems with magenta in my Pro10s. That was after starting to refill OEM carts with Octoinkjet. The problem disappeared for a while cleaning the printhead out of the printer but it reappeared in a few days, although to a lesser degree. Switching back to OEM ink and, later, to Precision colors PGI-72 magenta fixed totally the issue. I reckon it was an occasional batch of faulty ink because all the olther Octoinkjet inks never gave me the slightest trouble.

I observed this today (after about 100 prints, most A4, some A3 and A3+ without any issue).
Went away after 1 cleaning.

Your magenta strip looks like mine from last year when I had problems with this color. Not massive clogs but something not quite right. Goes away with cleaning but returns in a few days, specially after printing in a row several photos with plenty of red-magenta colors.
If this is regular Octoinkjet magenta I start to see a pattern. You, @Borut, me..
 
It is PGI-72M, first refill of an OEM cart (that was never refillled and emptied of remaining ink).
There is something with it.
Ordered a PGI-29M, good for 3 refills.
Will receive it on Monday, stop printing for now.

The positive is the 9 other inks (also the red) seem to behave normally (although see the banding in the dark blue elsewhere).
These things remind me of the early days of the PRO-9500 :(.
