Cause
Print head position adjustment is required.
What to Do
Press the printer's OK button to cancel the error.
If print results are not uniform (colors and lines are out of register, etc.), adjust the print head position.
If the print results are still not satisfactory after adjusting the print head position as described above, adjust the print head position manually from the computer.
