(2) Enter adjustment mode [05]. Change the values for codes [1688 to 1692] and [1698 to 1702] to adjust the
background density.
* The highlighted area will become highly visible, if the background density is increased.

* The value for automatic offsetting adjustment for background processing will be applied, only if the
automatic copy density mode is selected. On the other hand, the value for manual offsetting adjustment for
background processing will be applied, only if the 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 value for the code corresponding to the original mode (Text/Photo, Text, or Printed image) will affect
the copy image quality in the Full color mode and the Auto color mode.
* The value adjusted for the background density is shared in the Full color mode with the Printed image
mode selected and in the Black mode with the Photo mode selected. Therefore, adjusting the copy image
quality in either of the modes affects that in the other mode. Perform copy image quality adjustment in the
mode that is used for the adjustment, while checking that in the other 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.
