•The lead edge of the document is very different from the rest of the document (e.g., the lead edge contains a black border).

•To retain more light color information such as light gray or yellow
NOTE: If Photo is selected as the Original Type, the Off setting is automatically selected. The contrast can still be adjusted by pressing the key(s) beneath Image Quality Copy.

NOTE: All three Background Suppression settings can be adjusted further by changing the contrast setting in the Image Quality Copy area.
