Scan-quality problems

Prevent scan-quality 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 59

for instructions.

●

Adjust the software settings according to how you plan to use the scanned page. See

Scanner

resolution and color on page 107

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/CM2320series

or the support flyer that came

in the product box.

Blank pages

The original might have been loaded 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.

Place the original document face-down on
the flatbed scanner with the upper-left
corner of the document at the corner
indicated by the icon on the scanner.

Too light or dark

The resolution and color levels may be set
incorrectly.

Verify that you have the correct resolution
and color settings. See
