2.8 Adjusting Color Registrations
Follow the procedure below to adjust the color registration when first installing the printer
or after moving it to a new location.
1) Use the control panel to print the color registration adjustment chart.
2) From the lines to the right of the Y (yellow), M (magenta), and C (cyan) pattern, find
the values of the straightest lines.
Note:
You can also use the densest colors of the grid to find the straightest lines. The colors
printed at the highest density are those next to the straightest lines.

panel.
Note:
If 0 is not next to the straightest lines, repeat steps 2-5.
