< Determining Set Values >
From the lines at right of each grid pattern Y (yellow), M (magenta), or C (cyan) on the
printed color registration correction chart, the numeric value of a line most straight is
read.
Note:
The color density of each grid pattern is also helpful. The highest density indicates a
line most straight.
If the value of the most straight line is 0, no correction is necessary. Otherwise, make
a necessary correction according to the set value input procedure given next.
< Entering Set Values >
By using the control panel, enter numeric values read from the color registration
correction chart for corrections.
