Digital BW, The Print

I think mine comes from the black cart since I am getting those lines
with BO too. In fact I am getting to like the BO prints so much I may
 switch back to epson dye carts until the 1270 die (or when I have
$$$$ to get a 4000). And I really need some b/w prints done before the
end of the week.

If you print a nozzle check, you might see all lines being fine.. BUT,
the vertical lines between the check patterns and the numeric code
printed after the nozzle check lines are not perfect. This indicates
to me that the nozzles are not firing correctly all the time. They are
firing, but slightly wrong timing. With Epson OEM ink everything is fine. 

So I guess if the 1280 and CIS has the same problem.. There're really
some problems with the ink. I may as well start saving towards a 4000..
