*The value for the automatic offsetting adjustment for background processing will be applied, only if automatic copy density mode is selected. On the other hand, the value for the manual offsetting adjustment for background processing will be applied, only if manual copy density mode is selected.

*Set the value in increments of approximately 10, while checking the copy image until the optimum value is obtained.

*The outcome of the adjustment will affect only copying in Full color mode.

<Note> "Making the highlighted area more visible (or increasing the background density)" and "eliminating the background color (or decreasing the background density)" are mutually contradictory. If the background color is darkened to make the highlighted area more visible, the hue of the background may change.

After adjusting the background density, copy and check the copy image quality.

If further image quality adjustments are still necessary, use the next procedure.

(3) Press the [BASIC] button on the Control Panel. Press the [] button to increase the copy density.

After increasing the copy density, copy and check the copy image quality.

With the copy density set to the maximum, if further image quality adjustments are still necessary, the service technician must use the next procedure.
