Automatic Gradation Adjustment
You can recalibrate the machine when you notice irregularities in the colour of the copies or prints, such as when copies turn out to be different from the original in gradation, density, or colour.
This is a precise recalibration that is made to the gradation and density 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.
Automatic gradation adjustment may differ, depending on the optional equipment attached to the machine.
The following two types of gradation adjustments can be made:
Full Adjustment
This is a precise recalibration that is made to the gradation, density, and colour 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.
Quick Adjustment
This is a quick and simple adjustment that is made to the gradation, density, and colour settings of the machine. Recalibrations are made internally without outputting any test pages.

IMPORTANT

|
The following types of paper can be used with [Auto Adjust Gradation]. Do not use other types of paper.
Type: Thin and Plain
Size: A3, A4, 11" x 17", and LTR
It is recommended that you select [Full Adjust] when performing an automatic gradation adjustment. Select [Quick Adjust] for a quick, but less complete adjustment between regular full adjustment recalibrations.
Make sure that you place the test pages properly. Accurate recalibrations of the gradation and density settings of the machine cannot be made if the test pages are not scanned correctly.
Three test pages are output by the machine during this adjustment. This machine adjusts the toner and print speed according to the paper type. To make effective adjustments, select the correct paper type.
