Digital BW, The Print

I've had no problems to speak of using the clear empty C86 carts and
MIS inks.  I've got a set of EZN, EZW, and the color set that MIS
sells, along with their chip resetter.

I have had minor problems with air bubbles when changing carts, but
only occasionally, and nothing that settling overnight hasn't fixed
(I've probably gone at least three months since a bad nozzle check). 
Before I started using the clear empties, I refilled the MIS
pre-filled carts and had worse problems with air bubbles, but even
that was minor.

HTH,

Lee
