Scan-quality problems
Prevent scan-quality problems
The following are a few simple steps you can take to improve copy and scan quality.
● 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 39 for instructions.
● Adjust the software settings according to how you plan to use the scanned page. See Scanner
resolution and color on page 71 for more information.
● If your product frequently feeds more than one page at a time, the separation pad might need to
be replaced. Contact HP. See
www.hp.com/support/ljm1319 or the support flyer that came in the
product box.
● Use or make a carrier sheet to protect your originals.
