Digital BW, The Print

I really recommend against using the auto head clean- if there's a
channel that's just not printing it seems to suck out a lot of ink
from the others.  

I think you're better off doing nozzle checks and manual head cleans
and purge prints.  

I agree with the other poster about using the bottom fill adapter on
your carts, especially ones not seeming to print at all (for stubborn
channels try dripping a little bit of cleaning fluid on the spike they
go into and on the park pad).

I had one R1800 which just couldn't keep a consistent nozzle check no
matter what.  Pretty soon it didn't work any better with the OEM carts
and inks.  Epson replaced it with a new model that has no clogging
issues at all.
