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
as thick a book as a dictionary. In this case, the open cover admits light to the Original Glass surface, producing a scan
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.
RANGE ADJUSTMENT — Use and to select the appropriate sensitivity from 7 levels to detect the boundary
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 Document Cover is closed at the time of scanning.
