Maintenance and Troubleshooting
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.
What to do
This condition is normal. The scanner
automatically mimimizes the problem
if Quality & de-screening is selected
in the Image Type dialog box.
What to do
Make sure the EPSON TWAIN
Image Type and Destination
settings are correct.
When using the Film adapter, make
sure the opening near the hinges on
the document table is uncovered, or
the Film Adapter is closed when
scanning.
