I screwed up! My HP 6700 Officejet printer showed and error that I thought was low ink. It was the printer head. After about ten years it bit the dust. Unfortunately I opened the colour package and put the magenta cartridge in which did nothing to fix the problem. After looking up what really was the problem, I found out I could not fix it. I bought another printer but it uses a different cartridge so these full ones are for sale. purchased at Costco for $60. I will also include the cartridges that were in the printer when it broke down. There isn't much left on the colour cartridges but the black cartridge is about half full.
