The file size of a
scanned black-and-

menu on the [Scanning] tab of the
"ScanSnap Manager - Scan and Save Set-

which are printed-

document" checkbox (which
is in the "Read mode option"
window opened by clicking
the [Option] button on the

Mark the "Setting for text only document"
checkbox.
Scanned images are
not displayed on the
