Scanned image is of poor quality
Is the original a second-generation photo or picture?
Reprinted photographs, such as those in newspapers or magazines, are printed by using tiny
dots of ink that make an interpretation of the original photograph, which dramatically
decreases the quality. Often, the ink dots form unwanted patterns that can be detected when
the image is scanned, printed, or appears onscreen. If the following suggestions do not solve
your 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 your resolution and color settings are correct for the type of scan job that
you are performing. See
Scanner resolution and color for more information.
Is the image quality better when the document is 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).
Typically, you make this adjustment by opening Display in Windows Control Panel.
● Try adjusting the resolution and color settings in the scanner software. See
Scanner
resolution and color for more information.
Is the image skewed (crooked)?
The original might have been loaded incorrectly. Be sure to use the media guides when you
load the originals into the automatic document feeder (ADF). See
Loading originals to scan for
more information.
Does the scanned image show blotting, lines, vertical white
stripes, or any other defect?
If the scanner is dirty, the image that it produces does not have optimum clarity. See Cleaning
the outside of the device for instructions.
Do graphics look different from the original?
The graphics settings might not be suitable for the type of scan job that you are performing.
Try changing the graphics settings. See
Scanner resolution and color for more information.
