HP recognized and then failed

I was really hoping this cheaper alternative would help this poor graduate student save some money. The I installed them the printer recognized them as previously used HP cartridges and the levels read as full. I was so excited. The ink had a smell almost like windex, but I did not care because I got the ink at 1/4 the price I would have. Ink printed nicely. However, I went to use it today one week after installation, and now there is an error with the black ink. I tried to take it out and reinstall it, but it won't recognize it anymore and I cannot print anything. I am so disappointed because I really need to save the money.
