Grounding Color Area
As Figure 4.3 shows, the top 3-mm part of the read area on each surface should be left blank
(grounding color) by specifying a drop-out color. If the drop-out color cannot be specified, select
“Photo” for the document type (linedrawing or photograph).
For details of the drop-out color, see Page 4-8.
