Automatic Color Tone Correction

You can recalibrate the machine when you notice irregularities in the color of the copies or prints, such as when copies turn out to be different from the original in color.

This is a precise recalibration that is made to the color settings of the machine. The procedure involves making test pages and placing them on the platen glass for scanning. Once this is complete, the machine automatically corrects the irregularities.

IMPORTANT
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-K1 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. For more information on Automatic Gradation Adjustment (Full Adjust), see "Automatic Gradation Adjustment." 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.
