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
●If the room temperature has changed more than 5°C, repeat the calibration process.
