Adjust Color with "Auto Gradation Correction"

Return to Overview

When using the machine for the first time, it is necessary to adjust the gradation in order to obtain the optimum copy or print results.
There are two types of gradation adjustments that can be made: Full Correction and Quick Correction.

  • Full Correction

This is a precise adjustment. The procedure involves making test prints and placing them on the feeder for scanning. Once this is complete, the machine automatically corrects the irregularities.

  • For an accurate adjustment, do not use colored paper, transparencies, or labels. It is recommended that you use plain white paper when performing Full Correction.
  • Make sure that you place the test prints properly. Accurate adjustments cannot be made if the test prints are not scanned correctly.
  • Two sheets of A4 or LTR paper are required for test prints.
  • Quick Correction

This is a quick and simple adjustment. Adjustment is made internally without outputting any test prints.

  • It is recommended that you select <Full Correction> when performing an automatic gradation adjustment. Select <Quick Correction> for a quick, but less complete adjustment between regular full corrections.
