If your printouts contain misaligned vertical lines, you may need to align the print head. Your printer must be connected directly to your computer (not over a network) to use the Print Head Alignment utility.
Caution: Load plain paper that's at least 8.27 inches (210 mm) wide to prevent ink from spraying inside the printer and smudging your printouts.
Select one pattern each for rows 1, 2, and 3. Then enter the number of the best pattern for each row in the corresponding boxes on the screen.
