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
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 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.
