To perform the printhead mechanical registration adjustment:
1 Print a Quick Test Page. From the Diagnostics menu, navigate to :
REGISTRATION > Quick Test
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.
