You can copy the image with clear contours and lines by increasing the sharpness, or soften the copied image by decreasing the sharpness. Use this function when you want to sharpen blurred text and diagrams, or to reduce moire (a striped, wavy pattern) to smooth the finished image.
Set the sharpness to <High> when you want to copy originals containing text or fine lines. Set the sharpness to <Low> when you want to copy originals containing printed photographs or other halftones.
