Print cartridges aren’t working even though it says they’re full

[Zouland]

So for a while our printer only printed faint blue cyan when we tried to print black, and we stopped using it for a while. Recently I decided to look into the issue to try to fix it. According to the HP app the cartridges are full, so I tried to use a method to soak the cartridges in alcohol for a few hours and it actually seemed to work! However after about 4-5 pages they went back to only printing faded blue cyan, and even that faded more and more with each page.

Ink cartridges are expensive so I’m wondering if anyone knows if there’s a more permanent solution or if I should just bite the bullet and get new ones.
