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

Scanner

resolution and color 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

HP Customer Care or the flyer that came in the

all-in-one box.

●

Use or make a carrier sheet to protect your originals.

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.
