Digital BW, The Print

Jim, how are your nozzle checks? Is EVERY single line visible?

I suppose this could be a printer problem. I have never had that
problem.  For a long time now, everything has been working perfectly.

Send me every single setting you are using. EVERY single one.  (Also,
what color space are you using in Photoshop?)  If you have even one
wrong, this could be the result, if it's one of the really important ones.

If it IS a printhead, the injection of windex directly into the
printhead should clear it!
But if EVERY one of your nozzles check out, I wouldn't think you would
have a clog, or air in your tubes.
