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.
1 To correct, turn the printhead screw clockwise to rotate both edges clockwise.
2 To correct, turn the printhead screw counterclockwise to rotate both edges
counterclockwise.
Note: One full 360
‑
degree turn of the printhead screw will change the skew on both edges by roughly 0.5 mm (one
alignment indicator dot).
Warning—Potential Damage: Caution should be taken to not turn the printhead adjustment mechanism more
than a few turns counterclockwise, for the screw will fully back out and will become disassembled. Stop turning
the screw when you stop feeling resistance, you may need to turn it clockwise to reengage the screw into the
adjustment plate. Turning more than a few turns clockwise will bottom out the screw. If the adjustment screw is
difficult to turn, make sure that the printhead mounting screws are loose.
