At one point the printer with the cartridge installed were enrolled in HP instant ink program in which they mail you new in cartridges every month for a monthly fee. Once print cartridges are installed into the printer once the printer is enrolled they are then reprogrammed to only work if the printer is still enrolled in the program. If the printer is not enrolled then the cartridges will not work at all. You will need to go buy new ones as HP as locked the print cartridges out.
