Background Suppression

The Background Suppression enables you to make adjustments for documents that contain poor contrast between the foreground image and the background. Background Suppression monitors the pre-scans image, to ensure the best image quality possible. In the PRODUCTIVITY mode, there is no prescan, therefore Background Suppression is done while the document is being scanned.

NOTE: Off is the only choice for Photo, Scans, and Color Scanning.

Four choices are provided:

Off This setting disables Background Suppression. It produces a document that reproduces all the characteristics of the original document with minimum alteration. 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

(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, Copy area.
