Solution:

The solution depends on the type of unevenness.

Carry out the appropriate procedure from those in the following table:

(A) The density is uneven across the entire image.

Affected area

Solution

The density from top to bottom is uneven.

Illustration of density problems

  1. In the [Machine: Image Quality] group on the [Adjustment Settings for Skilled Operators] menu, select [Adjust Image Density] and execute [Image Density Adjustment: Manual Execute].

  2. If the problem persists, see Uneven Density from Top to Bottom.

The sides are fainter or denser.
