following suggestions do not solve the problem, you might need to use a better-quality
version of the original.
• To eliminate the patterns, try reducing the size of the image after scanning.
• Print the scanned image to see if the quality is better.
• Make sure that the resolution and color settings are correct for the type of scan job.
• For best results, use the flatbed scanner for scanning rather than the ADF.

Two-sided originals can "bleed" text or images from the back side to the scan if the
originals are printed on media that is too thin or too transparent.
• The image quality is better when printed
The image that appears on the screen is not always an accurate representation of
the quality of the scan.

gray). On Windows computers, you typically make this adjustment by opening
Display on the Windows control panel.
• Try adjusting the resolution and color settings.

The scanned image is skewed (crooked)
The original might have been loaded incorrectly. Be sure to use the media guides

Graphics look different from the original
The graphics settings might not be suitable for the type of scan job that you are
