This sounds like an interesting idea. Am I guessing correctly that the
main evil is that the printhead is "clogged" internally and the boiling
water dissolves the clog?

What is inside the printhead? I found a description of the printhead at

http://h10010.www1.hp.com/wwpc/us/en...637-34076.html
But the HP article didn't describe how a printhead works. If I knew how
it works (and what is inside that little tank) then I could better
figure out how to repair it.

Once we pull the printhead out of the boiling water, should I soak it
with ink from the top screen or leave it filled with the hot water
before putting the printhead back into the HP d145 officejet? Or do we
empty it out and put the printhead back into the all-in-one
printer/fax/scanner filled with air?

Thank you, in advance, for your kind help,
