If you feel dirt or debris, clean the glass again. 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.
