In addition to cleaning the scanner glass and glass strip with a soft lint-free cloth moistened with water, run
your fingertip 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 attempt.
When there is a spot of dirt or correction fluid on the glass strip, the printed sample shows a vertical line.
After the glass strip is cleaned, the vertical line is gone.
