Reading the gradation correction sheet
The printed gradation correction sheet is read as shown below.
Comparing the gradation correction sheet and correction value of each color, K (black), M
(magenta), and C (cyan)/Y (yellow) determine the required gradation correction and configure
settings using the control panel.
1. K (black) correction values
Used to adjust the color printed when only black toner is used. The currently set correction value is
printed in red.
2. M (magenta) correction values
Used to adjust the color printed when only magenta toner is used. The currently set correction value is
printed in red.
3. C (cyan)/Y (yellow) correction values
Used to correct the colors printed when cyan and yellow are used. For C/Y (cyan/yellow), the
correction value is determined based on combinations of these two colors, although panel settings are
configured for each color.
