A line of dots always appears in the scanned image.
Paper path guide or
document table is dusty
or scratched. If this happens on both your screen
and printout, the paper path guide of
the Auto Document Feeder or the
document table may be dusty or
scratched. Clean the paper path guide
as described on page 4-6, or clean the
document table. If the problem still
exists the guide may be scratched and
require replacement.
When using halftoning, textured patterns of dots appear
inside particular areas of the image.
