How can I still use my expired print cartridges since they are still full of ink. I don't want to buy new ones just because they are old, they should still work but the printer just says check and remove cartridges. It's an hp psc 2110xi printer. I read on one website that if you put tape of the contacts on the cartridges that that will reset the expiration date but it didn't work. I'm open to any suggestions on how to fix this problem.

I'm not aware of an expiration date built in to the cartridge (but it wouldn't suprise me). I use recycled HP cartridges in my HP Deskjet, i.e. they are HP cartridges that have been refilled (and tested) by a third party company, and the results have been variable but on the whole okay. If print quality is important I think your going to have to buy originals, otherwise I'd suggest you trade in your non-working cartridges for some refilled ones.

Be careful with tape around the contacts - if you get some adhesive on the cradle contacts you may damage them trying to clean it off, then your printer will never work properly.

I cannot vouch for this but it's worth a try:

How to reset HP ink cartridge expiration DRM
1) Remove and reinsert the battery of the printer’s memory chip
..
2) Preemptive: Change the parameters of the printer driver

I tried that but I can't find the battery. Its an hp psc 2100xi. It's really tight inside and I looked at everthing I could see and stuck my fingers in there to try and find it but no dice

I recall reading an article in a photo magazine that did a survey on top ten peeves; the high cost of ink cartridges topped the list (along with the minuscule amount of ink in the cartridges). It also said that some manufacturers were installing a chip in their ink cartridges that would allow them to be used only once to prevent refilling the cartridges (bummer). I don't recall reading anything about expiration dates being encoded.

I would try to contact Hewlitt Packard and see if they have a fix you could apply; if not, then see if they would replace your cartridges (with the cost of printer ink being higher than the cost of gold, they should be willing). You might try to check out some forums and see if anyone else has had this problem; if so, perhaps there might be some legal remedies -- at the very least to make HP cease and desist (I would think this constitutes robbery). If HP can't or won't help you, then I can only suggest you check expiration dates, don't take advantage of sales unless you know you will use the ink before the expiration date, and when it comes time to buy a new printer, get one that doesn't use shady tactics. Hopefully, other manufacturers won't take this practice up.

I'll email or call them tomorrow. really, this is so stupid, there is plenty of ink in them. when i was screwing around with that tape on the contacts idea I got ink all over my fingers so I know its there. Hopefully HP will do the right thing, thanks for the help.
