My printer says print cartridges not detected or missing. I've been using these steps to print out stuff.
1 - Hold the power and cancel button down (X)
2 - When it say enter special key combo press Blue, Green then Grey.
3 - Press BLUE again, now it says information menu.
4 - Press GREEN then GREY, now it says "checksum for relock data"
5 - Press GREEN again!!!
but after I print something out. It goes back to "print cartridges not detected or missing" I've tried taking out and putting back the ink cartridges, but still says the same thing. HELP!
