Scan-quality problems
Prevent problems
The following are a few simple steps you can take to improve copy and scan quality.
●
Use the flatbed scanner, rather than the automatic document feeder (ADF) input tray, to scan.
●
Use high-quality originals.
●
Load the media correctly. If the media is loaded incorrectly, it might skew, which causes unclear
images. See
Load paper and print media on page 26 for instructions.
●
Adjust the software settings according to how you plan to use the scanned page.
●
If your product frequently feeds more than one page at a time, you might need to replace the
separation pad. See
Replace the tray 2 and optional tray 3 separation pad on page 45.
●
Use or make a carrier sheet to protect your originals.

upside down.
In the automatic document feeder (ADF),
put the top end of the stack of originals
into the ADF input tray, with the media
stack face-up and the first page to be
scanned on top of the stack.
On the flatbed scanner, place the original
document face-down with the upper-left
corner of the document at the lower-right
corner of the glass.
Too light or dark. The resolution and color levels might be
set incorrectly.
Verify that you have the correct
resolution and color settings.

substance might be on the glass.
