Digital BW, The Print

Johnny,

It sure sounds like you are doing the right thing, but your symptoms 
really point to your having the wrong inks in the slots.  The nozzle
check is the easiest way to see each ink individually.  In the Epson
info you should see a diagram of the nozzle check that shows which
ink is in each nozzle pattern.   Then look at the nozzle pattern from
the piezo cartridge.  The Light Cyan pattern should have the same
ink as the Magenta pattern NOT the same as Cyan.  Likewise the
Light Magenta should match Yellow NOT Magenta.  Try this and
let us know what inks are where -- maybe they had a bad batch of
inks.
