Clean the document cover or document
glass.

the Document Glass on page 12-12.
When scanning highly translucent
documents, dirt on the document cover
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

scanning.
Adjust the scan density.
Select the proper Original Type for the

document might not be making proper
