This URL points to a reasonably good summary of how the general populace
might feel when confronted with a perfectly good ink sponge that's
"expired" prematurely ... or when encountering a printhead that is easy to
fix.

Particularly, it contains pictures of how to reset the CMOS date so that
the onerous HP ink tank expiration dates are no longer a problem.

Here's the relevant cut and paste, verbatim:
I opened the clam-like cartridge access to my printer (d125xi),
and looked for a battery. At first I didn't see it, but I was
determined. Finally, I saw it. On the left inside, near the
front of the machine, was a small button-type battery, held
in place by a spring clip.

First, I disconnected the power and the printer cable,
just to be sure. Then, I reached inside and carefully
removed the battery. I waited for about an hour, and then
reinserted the battery and plugged everything back in.
Viola! I was able to make a copy.

Tried printing-- that worked too.

I'm certain now that if I'd known this trick a few months ago,
I could have saved the money I had to spend on a printhead too.
