As a basic procedure, it is
recommended that the
adjustments be performed in the
following order: brightness,
contrast and color balance.
When the colors are unbalanced
to a great extent, the adjustment
work may be more efficiently
performed in the following order:
rough adjustment of brightness,
adjustment of color balanced,
fine adjustment of all parameters.

IMPORTANT:
●
Before making adjustments using the color control function, perform the calibration to make
sure that the machine is in appropriate condition.
●
The color control function may be used to produce prints in desired colors. After using the
function for that purpose, be sure to restore the normal settings for the next use.
●
The sample image used for color matching should be one with easily identifiable transitions
between colors and gray balance. If the sample image is biased towards particular colors, the
color adjustment will also be biased towards those colors, resulting in inappropriate color
reproduction when printing other images.
●
When accurate color matching is required, note the following:
●
It the temperature was low during the night, let the machine stand for about 1 hour after
power-on before starting printing.
●
If the room temperature has changed more than 5
°
C, repeat the calibration process.
