In Word, you can define the spacing between lines by using the Spacing Before and Spacing After paragraph formatting options. You can set these options through the Paragraph command on the Format menu or through the paragraph style. However, the scanning software cannot interpret line spacing defined in this way. So make sure that you do not use these options when you create scanning-enabled Looks and when you format questionnaires for scanning. Instead add additional spacing before or after a line by inserting additional blank lines.
