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. 62, and “TWAIN Driver Settings g,”

on p. 64.

• 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.
