5. Scanning-specific Adjustments

‰Procedure

*The adjustment is performed by the service technician only.

(1) Enter adjustment mode [05]. Change the values for codes [880 to 883] to adjust the gamma curve balance of the low-, medium- and high-density areas.

Color mode	Original mode	[05] code	Subcode	Value recommended	Acceptable	Default
					value range
	Text/Photo	05-880	0/1/2	Set a value smaller than 128
Black	Text	05-881	0/1/2	to decrease the density.	0 to 255	128
	Photo	05-882	0/1/2	Set a value larger than 128
				to increase the density.
Gray scale	---	05-883	0/1/2

*Set the value in increments of approximately 20, while checking the scanned-in image until the optimum value is obtained.

*The subcode varies, according to the area for which the density is adjusted. Refer to the table below and

set the subcode for the area to be adjusted.

Subcode	Area for the density to be adjusted
0	Low-density area
1	Medium-density area
2	High-density area

*Gradation in Black mode will significantly vary, if the medium-density area is mainly adjusted. But remember that adjusting the low- or high-density area will rarely affect the gradation in Black mode.

‰Cautions after the completion of the adjustment

Nothing in particular.
