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 gradation, density, or color.

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

• Make sure that you place the test prints properly. Accurate recalibrations of the gradation, density, and color settings of the machine cannot be made if the test prints are not scanned correctly.

• This machine adjusts the toner and print speed according to the paper type. To make effective adjustments, use plain paper.

• Test prints are not counted as part of the copy or print total page counts.

1. Press (Additional Functions) → [Adjustment/Cleaning] → [Auto Gradation adjustment].

2. Press [Test Print].

• If the paper which is appropriate for the test print is not loaded in a paper source, a message asking you to load the appropriate paper appear. In this case, load the appropriate paper in a paper source.

3. Place the test print on the platen glass.

Place the test print face down on the platen glass, with the black bands along the top left back edge of the platen glass by the arrow.

4. When auto gradation adjustment is complete, press [Start Scan].

5. Remove the test print from the platen glass.
