Digital BW, The Print

We had to abandon our 1280 about two years ago due to constant clogging and how we 
basically lost control of our Macs for the duration of the print. We had been using the 
original ConeTech Piezography BW system (not ICC) with the original Neutral Quad-Tone 
inks through their continuous ink system. Obviously, due to lack of use and time, the ink 
in the lines has evaporated and caused large packets of air. What needs to be done to 
return the 1280 to using the original Epson dye based color inks? Thanks.
