We are getting randomly distributed white dots on all colours containing magenta. Would air bubble cause something like this as they would not be ejected by the head to hit the surface anyway, must be a comtaminant of some sort ?
I too have experienced this as you have reported. At the time I was using the High Density print setting on my 64s. After changing it back to high quality setting it went away.
Thks it is indeed true that it shows much more on high density but I am still having it in high density. Waiting for a batch of fresh ink to arrive to flush and replace and see if it will improve.
