Thanks to Darren for posting that link to Robb's method (not our Robb, a
different Robb:-) ) for unclogging
dead heads.. it took a couple of days, but that, followed by the
standard head cleaning procedure and I got
a perfectly acceptable print just now.
Below is the essence of what Darren posted earlier. I used the formula
for the homemade stuff except using
plain household ammonia instead actual Windex, as that was the key
ingredient..
I also consulted a friend of mine who taught chemistry who immediately
pointed out that using vinegar instead
was a BAD idea!
I started out with a printer that produced a nozzle check pattern where
3 of the 8 ports were totally blocked, not
the tiniest bit if ink appearing.. a couple were ok with new ink and the
others spotty.
after a couple of days of Robb's procedure, and a total of about 6
standard head cleaning runs and 3 or 4
test with a test sheet I made up inspired by another vid I saw finally
today I have me a fully operational
R2400... Hurray!

His use of aquarium pump tubing as a reservoir/sight glass is ingenious.
Also worthwhile is his formula for DIY Inkjet print head cleaner:
