How long after the expiration date are HP ink cartridges usable for?

I have a few HP ink cartridges that have expired in December 2005, August 2007, and October 2007. Are these still usuable? Please let me know! Thank you!|||That depends upon the style of ink cartridge.





For older HP%26#039;s like a 26, 33, 29, or 20 (6614) the will actually %26quot;explode%26quot; not long after their expiration date (by explode i mean the bags over inflate forcing a large quantity of ink out) this destroys the electronic strip and makes a terrible mess.





For block style HP cartridges (anything small and square) it won%26#039;t make a difference, the expiration date is just a gauge of when HP guarantees the cartridge for resale.





As for the the large ink tank style HP, #10, #11, #14 and #88%26#039;s the expiration date is a stop date. They will not work beyond this date.|||If they are still taped, they shouldnt have dried out. If they have been used before, they are probably clogged......tryem out|||It is not like food in that it will harm you if you use them. Insert them into your printer and see if they work.


Honestly I%26#039;m sure HP wants you to toss them and go spend some $$ on new ones, but if they put ink to paper then they may be good for another 10 years.
