Note
In addition to cleaning the scanner glass
and glass strip with a non-flammable glass
cleaner, run your finger tip over the glass
to see if you can feel anything on it. If you
feel dirt or debris, clean the glass 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.
