You're correct. That's the way it's designed to (not)work and it is morally wrong. There are a couple of ways of working around it which I'll get to later. We have a CP1700 and a Business Inkjet 2230 which use the 10/11 cartridge system. We just opened a new sealed authentic HP black 10 cartridge #C4844A on 11/10/2005 and as soon as it was installed, before any printing, each printer would give the "Black Ink Cartridge Expired" message. We buy extra black cartridges so they sometimes sit on the shelf for a while. This one had gotten stuck in the back and the date printed on it is 10/30/2002. For these 2 printers at least, the computer's time and date is sent to the printer by the HP printer driver every time you print. So the printer compares the computer's date to the date burned into the cartridges chip and decides by some formula if the cartridge is too old or not. If the printer decides the cartridge is too old, it displays the "Expired" message. People claim the cartridge chip's date is not rewriteable (it's one-time-programmable) and I haven't seen any devices that rewrite the HP chip.
So, there are 2 solutions:
1. For the 2230 printer: First, turn the printer off. Whenever you need to print, set the computer date's year to something less than the cartridge year, like 2001 in my case. Turn the printer power on. After it does its self-test, the display should show the cartridge as good. Print what you want. When you are finished printing, set the computer's year back to the correct year (2005). If you need to print again, you must always set the computer's year to an old year BEFORE you print. If you forget, start this procedure from the beginning.
When I used this method on the 2230, the black cartridge from 2002 worked perfectly. There was nothing wrong with the ink. Color and saturation were as good as any cartridge. HP's excuse for having an expiration date is a complete LIE. A new sealed cartridge will work
long past their expiration date. I'm not sure what's happened to the lawsuit, but I hope they lose $Billions for trying to pull this. When these printers wear out, I'll be buying Canon printers next time.
I've read this method also works for the CP1700 if you remove a backup battery which powers its real time clock, but I haven't tried it yet. I have tried this method without removing the battery and it does not work.
2. Buy a replacement chip for the cartridge. The best chips are auto-resetting and are about $8. There are different ones for each cartridge type and color. They automatically reset the rewriteable level value in the chip to 100% when they get down to 10%. If you are going to refill it, it's a good practice to never let the cartridge get empty before you refill. Get into a habit of refilling it when it gets down to 25% full.

There seems to be a lot of sources in China, but I'm not sure if you can buy direct from them.

If there's one close to you, you can also try having the cartridge refilled/reset at a place like:

Hope this helps.
