Digital BW, The Print

OK so before I ever got the UT7s to give me a good nozzle check the
2200 decided not to recognize most of them as even being there.

I can't do another test or clean or check because the printer thinks
they are empty or heaven forbid 3rd party and it won't recognize them.

At first it liked them in there, now not so much.

Where do I go from here.  Maybe return them to MIS but why did they do
it?  The chips are on the carts. Removing and reinstalling them makes
no difference. Putting the OE carts back in and them reinstalling MIS
makes no difference. It likes the OE carts but not the UT7s.

Ideas?

Thanks

Neil
