Scan-quality problems
Preventing 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
Loading media into the input trays
for instructions.
●
Adjust the software settings according to how you plan to use the scanned page. See
for more information.
●
If your all-in-one frequently feeds more than one page at a time, the separation pad might need
to be replaced. Contact HP Customer Care. See
or the flyer that came in the
all-in-one box.
●
Use or make a carrier sheet to protect your originals.

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.
