■ Automatic Color Tone Correction

The hue of the image is automatically corrected by outputting a test page and reading it with
the optional Duplex Color Image Reader Unit-H1.
CAUTION:
• Make sure to perform this function in the stable room environment (i.e. temperature
and humidity). The color may become unstable due to the rapid changes in room
environment, especially soon after staring up an air conditioner during summer or
winter season.
• You can use this function only if the Duplex Color Image Reader Unit-H1 is attached.
• Make sure to perform "Automatic Gradation Adjustment (Full Adjust)" to correct
gradation and density settings before starting "Auto Correct Color Tone" to correct
color settings.
• This machine adjusts the toner and print speed according to the paper type. To make
effective adjustments, select the correct paper type.
• Make sure that you place the test pages properly. Accurate recalibrations of the color
settings of the machine cannot be made if the test pages are not scanned correctly.
NOTE:
Test pages are not counted as part of the copy or print total page counts.
