Yep, I'm on my second set of EZ carts (all positions) at this point. 
They were purchased separately, about seven weeks apart, and I purchased 
pre-filled carts; I've never refilled and reset the carts or anything 
like that.

No, I've not tried the Epson chip in the MIS cart. I'll put this on my 
list of things to do, but I'll hunt for the PDF you mentioned first.

I'm not knowledgeable about inkjet technology. Is the ink being fed by 
gravity and/or capillary action into the jet, or is there a pump? There 
is a large vent on the top of the MIS carts, which is not present on the 
OEM carts. Could its presence somehow be allowing excessive amounts of 
ink into the jet, thus resulting in dots on the paper when the jet 
clears itself?

That could be.

I don't think I have any traction to get Epson to do anything about it 
if it is, though. Since the printer works flawlessly with the Epson 
inks, it seems likely that Epson is going to say nothing is wrong, and 
I'm not sure I would have a basis to disagree with them. And I'm a 
little reluctant to head back down to CompUSA and buy a second printer; 
my wife might want to discuss concepts like "throwing good money after 
bad" if I do that. Not that I think the system is useless with the dots; 
I'm learning a ton from it, but I'm just picky enough to want it to be 
perfect.
