Problem Cause Solution
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.
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 printer and
scanner share memory, the
scan might be slower.
Scan quality problems
This section provides information about improving scan quality by preventing or correcting
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 trays for instructions.
● Adjust the software settings according to how you plan to use the scanned page. See
Scanner resolution and color for more information.
● If your device frequently feeds more than one page at a time, the separation pad might
need to be replaced. Contact HP Customer Care. See
Service and support or the flyer
that came in the printer box.
● Use or make a carrier sheet to protect your originals.
