Moiré (cross-hatch) patterns appear in the scanned image

A moiré is a cross-hatch pattern that appears on scanned images when scanning printed materials. It is a result of interference that occurs due to the difference between the pitches of the scanning and the halftone screens.

Try one or more of these solutions:

• Make sure Image Type is set to Color Document or Black & White Document in the Manual mode window.

• Change the Image Type settings. Turn the De-screening setting On in the Image Type dialog box.

• Place a transparent sheet such as an overhead projector sheet, between the document and the document table.

• Reposition the document slightly.

• Make the image size slightly smaller.
