shows up in the output. Place a sheet of
white paper over the document before
scanning.

document glass, and shadows can
resemble dirt in the scan. Place a
transparency or transparent film under the
document before scanning.
Adjust the scan density.
Select the proper Original Type for the

Cut-and-pasted or creased parts of the
document might not be making proper
