Scanned image is of poor quality
Solution Description
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 
scanned image. See Enhancing the scanned image in 
HP Document Manager 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. 
See Scanner resolution and color
 for more information.
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 in the Control 
Panel. See the documentation that came with your 
computer.
●
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. It is important 
to use the media guides when you load the originals. See 
Loading originals in the copier/scanner
 for more information.
Does the scanned image 
have unwanted blots, lines, 
vertical white stripes, or any 
other defect?
See Improving copy/scan quality for more information.
Is the scanner dirty?
If the scanner is dirty, the image produced will not have 
optimum clarity. See Cleaning the copier/scanner
 for 
instructions.
