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 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, when scanned and reprinted or displayed, 
can be detected. 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. Se
 for more information.
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. Se
 for more information.
For best results, use the flatbed scanner, not the ADF, for scanning.
Is the image quality better when printed?
The image displayed on the screen is not always an accurate representation of the quality of the 
scan.
Try adjusting the settings on your computer monitor to display more colors (or levels of gray). 
Typically, you make this adjustment by selecting Display, found on the Windows Control Panel.
Try adjusting the resolution and color settings in the scanner software. See 
 for more information.
Is the image skewed (crooked)?
The original might have been loaded incorrectly. It is important to use the media guides when you 
load the originals into the ADF. See 
 for more information.
Does the scanned image have blots, lines, vertical white stripes, or any 
other defect?
See 
 for more information.
Is the scanner dirty?
If the scanner is dirty, the image produced will not have optimum clarity. See 
 for instructions.
Do graphics appear 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, se
 for more information.
Part of the image did not scan or text is missing 
Was the original loaded correctly?
Make sure that you loaded the original correctly. See 
 for 
instructions.
