5.2 To Scan an Original, while Eliminating the Background Color

Before the adjustment
The background color of the original is also
scanned. Therefore, no clear contrast is made
between the background and image.
Explanation
When an original with a background is scanned, such as a newspaper and colored paper, the background color is
also scanned. Therefore, no clear contrast is made between the background and image. Perform background
adjustment, in order to clearly scan such originals.
* This adjustment will have an effect on the image scanned in all color modes. However, the adjustment
(procedure (2)) in adjustment mode [5] cannot be performed in the Gray scale mode and the Black 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 the effectiveness of the adjustment, restore the settings made in the previously used
procedure to the original ones. Then use other procedures.
* Both the service technician and the user can use procedure (1).
* Only the service technician must use procedure (2).
(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.
