Solution 1:
- Hold down the four "OK", "Cancel", "Black", and "Color" buttons at the same time and turn printer off
- Allow it so shut down normally but keep holding the buttons until shuts off, then turn it back on
- Release the four buttons.
- You will have to do this twice and then it should recalibrate
