My HP c4580 states that the cartridge is missing or undetected.So I reinstalled the cartridges and it says the samething,WHAT DO I DO?

It's a new cartridge you fitted?
If not, it's probably because it genuinely is empty.

If new:
Remove all the cartridges. Switch off the printer.
Switch the printer off and reinstall the cartridges.
Switch the printer on.
Switch the printer off.

If you continue to receive the same error message it's because the cartridge isn't fitted/seated correctly, or that cartridge has a problem.
