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] as the mode on the [Basic] tab
sheet. The background behind the text is removed or processed so
that the text is emphasized for better legibility.
When you want to remove the black
circles from scanned images when
scanning documents with punch holes
(when the background is set to black)
When the background color is set to black on the [Feeding] tab sheet,
select [Punch Hole Removal] on the [Image processing] tab sheet.
The black circles from the punch holes in documents are removed
from the scanned images.
Hint
When the background color is set to white, [Punch Hole Removal] is
disabled. When the background color is set to white and a document
with punch holes is scanned, the edges of holes may still appear in
the images.
When you want to match the orientation
of images to the text when scanning a
mixture of pages with different text
orientations
Select [Text Orientation Recognition] from [Document Orientation] on
the [Others] tab sheet.
