and skips saving any image it determines to be a blank page.
• You can adjust the sensitivity of the Skip Blank Page option
under [Contents detection sensitivity].
• The initial value for the Skip Blank Page option is set to "90."
As you lower the value from the default setting, pages of the
document with text become more likely to be skipped as well.
As you raise the value from the default setting, pages of the
document that are blank become less likely to be skipped.
IMPORTANT
• The scanning speed may be reduced when [Skip Blank Page]
is selected.
• A resolution of [400 dpi] or more cannot be set when [Folio] is
selected. In addition, [Double feed detection by Ultrasonic]
cannot be selected.

document before scanning the entire document.
Hint
• Scanning pauses after the first page of the document is
scanned, and the image of the first page is displayed.
• Use the displayed image to confirm and adjust the brightness
and contrast. Press [Continue] to confirm the adjusted
brightness and contrast for the first image and continue
scanning.
