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

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.

exposure glass and the shading correction plate of the revolver. For details, see "Cleaning the TIM-
Mag Unit", Maintenance and Management.
