Check the Quick Test Page for any sign of misalignment by checking the diamonds at the top left and top
right of the test page for equal distance from the top of the page. If necessary, rotate the printhead to the
left or right and tighten down the mounting screws and check for proper alignment again by running another
Quick Test Page. This procedure may take two or three attempts before you get satisfactory results.
