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. Change to the Normal or Best setting.

•Check the original

◦The accuracy of the copy depends on the quality and size of the original. Use the Copy menu to adjust the brightness of the copy. 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 reduce/enlarge or other copy feature might have been set from the device control panel to reduce the scanned image. Check the settings for the copy job to make sure that they are for normal size.

•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.

Copy defects are apparent

•Vertical white or faded stripes

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.

•Too light or dark

Try adjusting the contrast and copy-quality settings.
