Toshiba e-STUDIO281c, 451C, 351C manual Gray scale 05-848

5. Scanning-specific Adjustments

(2) Enter adjustment mode [05]. Change the values for codes [1070 to 1072] or [848] to decrease the background density.

•The code to use varies, according to color mode (Full color mode or Gray scale mode). Adjust the value for the [05] code corresponding to color mode for which you would like to improve the image quality.

Color mode	Original mode		[05] code	Value recommended	Acceptable	Default
					value range
Full color	Text		05-1070	Set a value larger than 0.	0 to 50	0
	Printed image	05-1071
	Photo	05-1072
Gray scale	---		05-848	Set a value smaller than 128.	0 to 255	128

*Set the value, as follows, while checking the scanned-in image until the optimum value is obtained.

• Adjustment in Full color mode:	Set the value in increments of approximately 10.
• Adjustment in Gray scale mode:	Set the value in increments of approximately 20.

*The background density in Full color mode (code 05-1070, 1071 or 1072) will become the highest, if "0" is set. On the other hand, it will become the lowest, if "50" is set. Changing the value will also change the background density in Full color mode, when the "Background Adjustment" indicator is set to the center. Then, if the background density of the center value is changed, each step of the indicator will be changed accordingly. (For instance, if the center value is increased by 5 (lighter), the value of each step of the indicator will also be increased by 5 (lighter)).

*The background density in Gray scale mode (05-848) will become the lowest, if "0" is set. On the other hand, it will become the highest, if "255" is set. Changing the value will also change the background density in Gray scale mode, when the "Background Adjustment" indicator is set to the center. Each step of the background density indicator will be changed, based on the values for codes 05-853 and 858. They are intended to adjust the amount of change in the output background density per step defined in manual density mode.

‰Cautions after the completion of the adjustment

The adjustment may possibly diminish the quality of the light-colored image. Therefore, carefully perform the adjustment, while checking the scanned-in image.

‰Remarks

When scanning the original, use the following steps to change the default indicator position in the background adjustment option, which is displayed on the Control Panel:

(a)Press the [USER FUNCTIONS] button on the Control Panel to enter the "User Functions" menu.

(b)Press the [USER] button.

(c)Press the [SCAN] button.

(d)In the "BACKGROUND ADJUSTMENT" option in Full color mode or Gray scale mode, specify the default background density.
