> I pulled out the carts and took a Q-tip cotton swab and dipped it into
isopropyl alcohol (rubbing alcohol).  I carefully swabbed the tip of the
"nipple" that stick up into the ink carts. This nipple is in the head unit,
not the CIS.  Then I inserted the carts, put a few drops of alcohol on the
sponge and did a head cleaning cycle.

> Now, I don't know if there are any detrimental effects of doing this or
using alcohol, so I write this with a warning that this was my experiment
that I resorted to when out of patience.  Perhaps others will know of
reasons why this should not be done. But I am printing once again and happy.

I've also been using isoprophyl (since I ran out of Windex). It seems to
work just as well. One word of caution, though. I'd be worried about any
possible lint from the Q-tip getting into the nipple. I don't know if the
nipple is filtered or not. It might be safer to apply the fluid with a
syringe.
