2.6.2 To Adjust the Copy Image Quality in Full Color Mode

*You can start with any of the procedures. But it is recommended to perform the procedures in order, as listed below. You can use one procedure in conjunction with another. But if this changes the image quality more than required or loses effectiveness of the adjustment, restore the settings made in the previously used procedure to the original. Then perform the next procedure.

*Procedures (1) and (3) are used by the service technician, and by the user.

*Procedure (2) is used by the service technician only.

(1) Press the [IMAGE] button on the Control Panel. Press the [BACKGROUND ADJUSTMENT] button. Press the [LIGHT] button to decrease the background density.

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

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

(2) Enter adjustment mode [05]. Change the values for codes [1688 to 1692] and [1698 to 1702] to adjust the background density.

Adjustment	Original mode	[05] code	Value recommended	Acceptable	Default
				value range
Automatic offsetting	Text/Photo	05-1688
	Text	05-1689
adjustment for	Printed image	05-1690
background processing	Photo	05-1691
	Map	05-1692	Set a value smaller than 128.	0 to 255	128
Manual offsetting	Text/Photo	05-1698
	Text	05-1699
adjustment for	Printed image	05-1700
background processing	Photo	05-1701
	Map	05-1702

*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 density of the background color is decreased, the highlighted area may become less visible.

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

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