5.2 To Scan the Original, while Eliminating the Background Color
(To eliminate the background density)
Before the adjustment After the adjustment
The background color of the original is also
scanned. Therefore, no clear contrast is made
between the background and image.
The background color is eliminated, allowing
clear contrast between the background and
image.
Explanation
When an original with a background color is scanned, such as a newspaper and color paper, the background
color is also scanned. Therefore, no clear contrast is made between the background and image. Perform the
background adjustment, in order to clearly scan this type of original.
* This adjustment will have an effect only on the image scanned in Full color mode (including Auto color mode)
or Gray scale mode.
Procedures
* 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.
* Procedure (1) is used by the service technician, and by the user.
* Procedure (2) is used by the service technician only.
(1) When scanning the original, press the [EDIT] button on the Control Panel. Press the [BACKGROUND
ADJUSTMENT] button. Press the [ ] button to decrease the background density.
After decreasing the background density, scan the original and check the scanned-in 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.
