Documents are missing or faded

Check the media

The media might not meet Hewlett-Packard media specifications (for example, the media is too moist or too rough). See Understand specifications for supported media for more information.

Check the settings

The quality setting of Fast (which produces draft-quality copies) might be responsible for the missing or faded documents. From the copy software on your computer, open the printer driver and change to the Normal or Best setting.

Check the original

The accuracy of the copy depends on the quality and size of the original. If the original is too light, the copy might not be able to compensate, even if you adjust the contrast.

Colored backgrounds might cause images in the foreground to blend into the background, or the background might appear in a different shade.

Size is reduced

The HP photo and imaging software settings might be set to reduce the scanned image. Change the settings, if needed. See the onscreen Help for the HP photo and imaging software for more information.

Copy quality is poor

Take steps to improve the copy quality

Use quality originals.

Load the media correctly. If the media is loaded incorrectly, it might skew, causing unclear images. See Understand specifications for supported media for more information.

Use or make a carrier sheet to protect your originals.

Check the device

The scanner lid might not be closed properly.

The scanner glass or lid backing might need cleaning. See Clean the device for more information.

The ADF might need cleaning. See Clean the device for more information.
