The key is to choose an inkjet carefully.

Hi SMS,

At first I thought you were "clueless in San Jose",
but then I read your wonderful post, and I realized you
were right on the money!

One thing to add to your "choose your printer carefully" advice.

This HP web site tells us that there is no way to override the
drop dead date in "some" HP printers.

Trust me, I've tried (on the d135).
It just can not be done.
Forget CMOS resets.
Forget motherboard shorts.
Forget changing the printer time.
Forget turning off the ink-drop counting mechanisms.
Even forget the otherwise venerable trick of cycling of three cartridges.

The only solution (for those printers) is to NEVER BUY THOSE PRINTERS!
Otherwise, attempting to re-fill the chipped ink will be sheer hell.

So that others benefit, we should add that list of printers to avoid
in order to eliminate hell in your otherwise wonderful instructions!

Thanks for your summary. I would disagree with the inclusion of the HP1700c A3 printer. I removed the internal battery from the printer and have never had any refusal on date of either heads or ink cartridges. I use this printer solely on expired parts and use it a LOT. The printer has its own internal date system. It looks at each installed cartridge and head individually. I use a CIS ink system and there is never a problem. The chips on those don't take a count. One problem that does exist is the counter on the heads that can't be overridden. Unless anyone else knows differently...
