[Compression] tab
■ Compression rate:
Control the compression rate to specify the size of the file for the scanned image.
The compression rate is controlled by moving the slider bar.
The larger the compression rate number is specified, the higher the compression rate is
set and the smaller the file size becomes.
■ Enable High Compression:
When this checkbox is marked, the compression rate increases compared to the ordi-
nary compression mehtod and the file sizes becomes even smaller.
ATTENTION

When the compression rate is increased, the quality of scanned images
deteriorates.

This function compresses characters and backgrounds on the docu-
ment separately. So using this function on the document which con-
tains almost text characters, the file size becomes smaller while
leaving the characters as they are. Meanwhile, this function is not
appropriate for scanning photographs or figures, because such draw-
ings are recognized as background and compressed as such, so the
qualities of such images will deteriorate.
