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.

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.
