Text or images on the back of a two-sided original appear in the scan

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 scanned image is skewed (crooked)

The original might have been placed incorrectly. Be sure to use the media guides when you place the original on the scanner glass. For more information, see Load an original on the scanner glass.

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.

Try adjusting your computer monitor settings to use more colors (or levels of 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 shows blots, lines, vertical white stripes, or other defects

If the scanner glass is dirty, the image produced does not have optimum clarity. See Maintain the device for cleaning instructions.

The defects might be on the original and not a result of the scanning process.
