Clean the scanning glass. (SF-300 Series)


If scanned images contain streaks or scanned documents become dirty, the scanning glass inside the scanner may be dirty. Use this procedure to clean them on a regular basis.

  1. Pull the lock lever toward you and then fully open the panel unit.

    The opne/close movement of the panel unit is linked to the up/down movement of the document eject tray. Do not press on the document eject tray when you open the panel unit.

  2. Use commercially available air blower to remove any dust and paper particles that have accumulated inside the scanner.

  3. Use a clean, dry cloth to wipe any dirt off the scanning glass.

    There is one scanning glass for the front side of documents, and another for the back side. Wipe of them clean.

    Do not spray water or detergent directly on the scanner. Doing so may damage precision mechanisms, such as the light source.

    Scratches on the scanning glass may cause streaks on scanned images, as well as feeding errors.
