Viewing the Color Calibration Sample Sheet and Gradation 
Correction Sheet
The color gradation correction value setting sheet contains two color sample col-
umns “Sample 1” column for setting the highlight part, and “Sample 2” column
for setting the medium part.
Similarly, the gradation correction sheet contains: “Gradation correction sheet
1” for setting the highlight part and “Gradation correction sheet 2” for setting
the medium part. Gradation correction sheet 1 is used for correction 1, while
Gradation correction sheet 2 is used for correction 2.
❖Color sample and correction values
The following explains how to view the color sample of the Color Calibration
Sample Sheet and the correction values of the gradation correction sheet.
This explanation uses setting K (black) as an example. The setting method for
M (magenta) is similar. For C/Y (cyan/yellow), the correction value is deter-
mined based on combinations of these two colors, although panel settings are
made for each color.
Note
❒Hold the correction value (0-6) for “K” of the correction value setting sheet
over the color sample of gradation correction 1 of the Color Calibration
Sample Sheet and search for a corrected color closest to that of the color
sample, and then set its correction value using the operation panel. The
currently set correction value is printed in red.

❖Relationship between gradation correction sheet and display
The printed gradation correction sheet and display correspond as shown in
the following diagram:
Comparing at the gradation correction sheet and correction value of each
color, K (black), M (magenta), and C (cyan)/Y (yellow), determine the grada-
tion correction and make settings using the control panel.
Note
❒XXXX represents the printer model name.
AK (black) correction values
Adjust the printed color when only black toner is used. The currently set
correction value is printed in red.
BM (magenta) correction values
Adjust the printed color when only magenta toner is used. The currently
set correction value is printed in red.
CC (cyan)/Y (yellow) correction values
Correct the color printed when cyan and yellow are used. For C/Y (cy-
an/yellow), the correction value is determined based on a combination of
these two colors, although settings are made for separately each color.
DK, M, C/Y
The numerical value set at time of gradation correction sheet printing is
displayed. This corresponds to the numerical value set using the operation
panel.
