The equipment may not detect blank pages correctly in the following cases:
The original consists of half-tone pages.
Pages contain small text/images, such as a page number printed on a blank page.
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.
