DEFAULT. The paper loaded is recognized as HP paper, which is already optimized and calibrated for the printer. Do Not calibrate the Paper Advance for this paper.
RECOMMENDED. The paper loaded is NOT recognized as HP paper, and Paper Advance values have NOT been customized for this paper type. In this case, calibrate the Paper Advance from the user menu.
OK. This indicates that the paper loaded has been calibrated before. If the printer continues to have banding and graininess problems, calibrate the Paper Advance from the user menu.
Whenever the printer's firmware is upgraded, the paper advance calibration values will be reset to factory default.
