Copy problems
Prevent copy problems
The following are a few simple steps you can take to improve copy quality:
●Copy from the flatbed scanner. This will produce a higher quality copy than copying from the
automatic document feeder (ADF).
●Use quality originals.
●Load the media correctly. If the media is loaded incorrectly, it might skew, causing unclear images
and problems with the OCR program. See 
Load paper and print media on page 58 for instructions.
●Adjust the control panel settings for the type of original if the automatic settings do not produce the
desired result.

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 the resolution settings are
correct for the type of scan job that you
are performing. See 
Scanner
resolution and color on page 100.
●For best results, use the flatbed
scanner for scanning rather than the
automatic document feeder (ADF).
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 settings in
the scanner software. See

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
product and scanner share memory, the
scan might be slower.
The scanning PC may not have enough
available resources.Close unused applications on the PC. If the
scan is still too slow, try rebooting the
scanning PC.
Antivirus, antispyware, or firewall software
on the scanning PC may slow scanning.Consult your antivirus, antispyware, or
