In addition to cleaning the glass strips with a non-flammable glass cleaner, 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, scan a document after each cleaning attempt. | | | | | | If there is a spot of dirt or correction fluid on the glass strip it may result in a vertical line as shown in the image. | | After cleaning the glass strip the vertical line is no longer present. | |
