[Density Difference Printing: Across Feed]

To reduce vertical image density differences, load 18 sheets of paper with a minimum of 279 mm/420 mm long in the tray.

Perform this adjustment only if the image density difference across the feed direction are noticeable when:

Replacing the photoconductor unit or charger unit
Changing 0520 [Special Toner Position] from [Print Special Toner First] to [Print Special Toner Last]

Make sure you have at least 18 sheets of A3 or larger paper.

Load paper into all paper trays except Tray 1.

Press [Density Difference Printing: Across Feed].

The machine prints 16 image-adjustment sheets.

At the same time, the in-line sensor scans the adjustment images and calculates the laser intensity adjustment value.

After two image-adjustment sheets are printed, press [Apply].

If you do not apply the adjustment value, press [Stop].

It is not required to perform this adjustment every time you change paper.
Performing this adjustment repeatedly will not remove image density differences. Perform this only once when image density differences are noticeable.
If black streaks appear after this adjustment is performed, clean the surface of the exposure glass of the in-line sensor and the shading correction plate of the revolver. For details, see Notes for Users.
