Variation on this, have you tried the Epson chip on the MIS cart? 
Just wondering if maybe the firmware is letting it leak a little 
because of the non Epson chip. What it sounds like is that the ink is 
being discharged when the head is oscilating to prevent the ink from 
drying in the jet. There is a description of this somewhere on the 
Epson website in a well hidden PDF about their inkjet technology. 
Normally if the ink builds into a drop, you get a very large spot on 
your print. A drop is a drop and they all have about the same size as 
determined by things like surface tension, safe to say a real drop is 
very large after it hits the paper. I've never seen one as small as 
you describe which really lends to the possibility that it is being 
semi-sprayed.
