Locate the printhead adjustment screw access hole in the front of the printhead access cover. This will require a
3mm hex wrench to adjust. A ballhead hex wrench is suggested to make it easier to find the screw head.

Check the Quick Test Page for any sign of misalignment by checking the diamonds at the bottom left and bottom
right of the test page for equal distance from the bottom of the page. If necessary, rotate the printhead adjusting
screw with a 3mm hex wrench either clockwise (to rotate the image clockwise) or counterclockwise (to rotate the
image counterclockwise), and run another Quick Test Page. One full 360-degree turn of the printhead screw will
change the skew on both edges by roughly 0.5mm (1 alignment indicator dot). You may need to repeat this step
two or three times before you get satisfactory bottom skew results.
