Background Suppression
The Background Suppression option enables you to make adjustments
for documents that contain poor contrast between the foreground image
and the background.
Four Background Suppression choices are provided:
Off This setting disables Background Suppression . All the
characteristics of the original document with minimum alteration are
reproduced on the copy. Choose this selection when:
•
The lead edge of the document is very different from the rest of
the document (e.g., the lead edge contains a black border).
•
Maps with grayscale or color content may copy best in this
mode.
•
To retain more light color information such as light gray or yellow
NOTE: If Photo or Color 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 .
(Light) This setting works best for documents on translucent or
transparent media, such as vellum (tracing paper) or film, or with medium
levels of colored background on opaque media or for documents. Such
documents have a higher contrast between the foreground and
background than dark documents, but less contrast than normal
documents.
(Dark) Use this setting for documents with a dark background
or with medium contrast between the foreground and background. In
this mode, the background is not suppressed, but the foreground image
is improved to increase the contrast.
Auto (factory default) - The Scanner automatically adjusts the image
quality parameters to obtain the best copy.
NOTE: All three Background Suppression settings can be adjusted
further by changing the contrast setting in the Image Quality and Copy
area.
