    Straight lines in the image come out jagged. Make sure the document orientation is perfectly straight on the document table. Align vertical and horizontal lines with the scales at the top and side of the document table. The image does not look the same as the original. Make sure the image settings of your software are appropriate for the type of image you want to scan.

    Printed colors Printed colors will not exactly match the colors on your monitor, since printers and monitors use different color systems: monitors use RGB (red, green, and blue), while printers typically use CMYK (cyan, magenta, yellow, and black). Check your software and printer documentation, or contact your printer company, for information on color matching and calibration.
