* This functions, only when “Multifeed Detection” is enabled.
* Skew Detection is a function used for detecting over-skew to stop feeding skewed
documents. If sheets of paper are stapled together, miss-detection may occur.
♦ Blank page skip
This option skips blank pages (blank pages or completely black pages) during ADF
continuous scanning.
Marking this check box, this function is enabled.
*This function can be used if “Ram cache” or “Use Both Memory” is selected.
If an item other than “Ram cache” or “Use Both Memory” has been selected in the
“Cache Mode:” and this check box is marked, it will change to “Ram cache”.

black pages, use the [White Dots Ratio] scroll bar to set the skip condition.

scanned document is below this value, it is recognized as a blank page. The setting range
is OFF(- -) and 0.2% to 3.0% (in increments of 0.2%).
*1: Ratio of black dots included in the scanning area (for white pages)
In case of Color or Grayscale
Use the slider bar to set the skip condition in five stages from 1 to 5.
To make the blank pages easy to skip, increase the value of the setting.
