Correction Gradation

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.

Full Correction

This is a precise recalibration for the machine's gradation, density, and color settings. 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. note:

• 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.
• Two test prints are output by the machine during this adjustment. Make sure that a sufficient supply of LTR or A4 paper is loaded into the machine before starting this procedure.
• Test prints are not counted as part of the copy or print total page counts.
• It takes approximately 300 seconds to perform the Full Correction.
