Erasing black frames around images

You may want to scan originals with the original cover left open especially when they are as small as a drivers license or

image with a black outer frame. This black frame can be erased using the Outside Erase feature.
[ON]—Select this option to enable the Outside Erase feature. Pressing the button makes the Range Adjustment slider
available.
[OFF]—Select this option to disable the Outside Erase feature.

between the image and outer frame. The higher the level, the more area is erased.
The sensitivity level for detecting images and the outer frame can be changed for each job using the control panel.
The Outside Erase feature is not available for the e-STUDIO855 Series.
Regardless of the settings, this feature is disabled under the following conditions:
- The Document Cover is closed at the time of scanning.
- The originals are scanned from the Reversing Automatic Document Feeder*.
Set the appropriate exposure manually. Enabling Outside Erase cancels the automatic exposure adjustment
feature.
