Cleaning the document scanner glass (top scanner glass)

Cleaning the scanner glass will remove lines from from your scanned documents. If you are scanning the documents to email or a folder, a dirty scanner glass will cause lines on your document scans. And if you copy the scanned documents you will have lines on your copies as well. Some models will have two scanner glasses (for scanning both sides of a document with a single pass) and some models will only have one scanner glass. A dirty scanner glass will not cause lines on print jobs sent from a computer because the scanner is not being used, the image is sent to the copier from the computer. If you are getting lines on print jobs sent from your computer, use the cleaning steps above (cleaning the charger grid & laser slit glass). Clean the glass very carefully. You do not want to scratch the glass. Using glass cleaner or water applied to a clean dry cloth is recommended. Do not apply glass cleaner or water directly to the glass because it could run past the glass and enter delicate areas of the machine.  It is important to remove even the smallest spec. The scanners are very sensitive and will pick up on debris that very hard for the human eye to see. The paper will be moving over the glass, so a spot becomes a line to the scanner.

Open the document feeder and push the green button to lower the scanner glass assembly.
