Practical Examples
When you want to enhance text that is difficult to read
because of factors such as the background of the
scanned document
Select [Advanced Text Enhancement] or [Advanced Text
Enhancement II] in the mode setting on the [Basic] tab. The
background behind the text is removed or processed so that the text
is emphasized for better readability.
 Advanced Text Enhancement is suitable for a document with a
light background color or a document with a non-uniform back-
ground (such as a pattern). If the background is uniform, it is
removed where it surrounds the text, and if the background is
non-uniform, it is processed to enhance text readability.
 Advanced Text Enhancement II is suitable for scanning a docu-
ment with a uniform background color and light text and back-
ground. If the background is non-uniform, such as a pattern, the
background may not be able to be completely removed and the
text may become difficult to read. If necessary, you can make
the text in scanned images easier to read by adjusting the con-
trast on the [Brightness] tab.
Practical Examples
