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 s like a 26, 33, 29, or 20 (6614) the will actually quot;explodequot; 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 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 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 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.
