Digital BW, The Print

I was using original epson inks (it works well)and change theses for 
the MIS GP (eboni K and Universal K) and refill the carts following 
the MIS instructions but I could not get any print, always my nozzles 
has gaps. I let the print rest for some days and no luck. I take of 
all the inks for the carts, clean with windex and plain water to 
clean a possible foam in the damper and refill again, but no luck.
I get all the possible problems, air, dripping inks,  banding 
issues...etc.
I see also a possible desing problems of those carts. Take a look to 
this image of the clamps

I make a pinhole directly underneath the ventillation hole in the 
cellafane cover, but the banding issues is still there
So...
