Digital BW, The Print

Dear all:

After a long vacation, my 1280 seems to frown. I purchased the new UT2, and I have 
installed them. I had some remaining ebony, that seems to have clogged, due to 
some inactivity, the heads. I have heard that some of you "windex" the heads when 
you cannot get a good cleaning. Can you, please, explain me the proccedure.

Thank you
J.
