Using the Scanner
Scanning Documents Containing Blank Sheets
• I want to skip blank sheets contained in a document stack.
Set “Scanning Side” to [Skip blank page]. [Double-sided scanning] is not
performed, and blank pages are skipped.
See “ISIS Driver Settings
g
,” on p. 50, and “TWAIN Driver Settings
g
,”
on p. 52.
• Blank sheets are not skipped even if [Skip blank page] is set.
Set a higher [Ratio of black pixels] value (adjust the slider towards the right).
If a low [Ratio of black pixels] value is set, blank sheets are sometimes not
skipped due to the background color or dirt on the document.
• Documents full of text are skipped as blank sheets.
Set a lower [Ratio of black pixels] value (adjust the slider towards the left).
If a high [Ratio of black pixels] value is set, even documents full of text are
sometimes skipped as blank sheets.
When a blank sheet is not skipped, adjust the slider to the right.
When a text document is skipped, adjust the slider to the right.
