Digital BW, The Print

I just purchased a set of MIS carts, refillable, for an r260.  I loaded 
one (eboni) and put it in.  I couldn't print, and the utility showed 
all carts (not just the eboni cart) x'd out (not compatible).  I put 
the original epson back in, no problem.

MIS tech support said to load them all, put them all in.  I did.  Same 
result.

In spite of having signed up several days ago, and been validated, I 
don't seem to have posting privileges in the MIS forum.

Seems like the chips (or some of them, or one of them) are NG.  But 
I've never done this before -- always stuck with originals with my 
2200.

Anyone have this experience?
