In addition to cleaning the scanner glass

cleaner, run your finger tip over the glass
strip to see if you can feel anything on it. If
you feel dirt or debris, clean the glass strip
again concentrating on that area.
You may need to repeat the cleaning
process three or four times. To test, make
a copy after each cleaning.
