To perform the printhead mechanical registration adjustment:
1 Print a Quick Test Page. See “Adjustments” on page 271. If the skew between the bottom left and bottom right
alignment indicators is greater than 0.5mm (1 dot), then proceed with adjustment. Otherwise, no polygon printhead
adjustment is needed.
2 Raise the paper support located in the top of the standard bin to its upright position to locate the three access holes
as shown in the illustration below.
3 Loosen, by a half turn, each of the three printhead mounting screws securing the printhead to the printer frame.
This will require a 5.5mm hex-socket screwdriver.
4 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.
