The scanned image is of
poor quality.
The original might be a second-
generation photo or picture.
●
To eliminate the patterns, try reducing the size of the
image after scanning.
●
Print the scanned image to see if the quality is better.
●
Verify that your resolution and color settings are
correct for the type of scan job that you are
performing. See
Scanner resolution and color
on page 61.
The image that appears on the screen
might not be 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
on page 61.

flatbed scanner. See
Loading documents to copy or scan

A colored background might be causing
images in the foreground to blend into
the background.
Try adjusting the settings before you scan the original or
enhancing the image after you scan the original. See

resolution and color on page 61.
The original is too small. The minimum size that the flatbed scanner supports is 25 x
25 mm (1 x 1 inch).
The media size is incorrect. In Scan settings, make sure that the input media size is large
enough for the document that you are scanning. See
Scanner
resolution and color on page 61.
The scan takes too long The resolution or color level is set too
high.
Change the resolution and color level settings to the correct
settings for your job. See
Scanner resolution and color
on page 61.
The software is set to scan in color. The system default is color, which takes longer to scan even
when scanning a monochrome original. If you acquire an
image through TWAIN or WIA, you can change the settings so
that the original scans in grayscale or black-and-white. See
the device software Help for details.
A print job or copy job was sent before
you tried to scan.
If someone sent a print job or copy job before you tried to
scan, the scan will start if the scanner is not busy. However,
because the device and scanner share memory, the scan
might be slower.
