Cleaning the Shading Boards

The shading boards are the white standard boards located behind the platen rollers. A dirty shading board may alter scanned colors or cause marks on the images.

1. Turn ON the power.

2. Hold the Upper unit as shown in the diagram, and open it slowly until it stops.
       

   
    The pickup roller is located in the middle of the Upper unit. Do not hold the protrusion on the Upper unit when you open it. Doing so may deform the pickup roller or cause a feeding error.

   
    Be sure to open the Upper unit until it stops. If it is not opened all the way, the shading boards cannot come out.

3. Press the Start Button for about two seconds.
    The shading boards come out above the platen rollers (upper and lower).
   

4. Wipe only the surface of the shading boards with a firmly wrung cloth moistened with water. Do not wipe the back side of the shading boards. Be careful not to bend the shading boards while doing so.

   
    Wipe the upper and lower shading boards. Do not spray water or detergent directly on the shading boards. Precision mechanisms, such as the light source, may be damaged.

5. Press the stop button.
    The shading board goes back in.

6. Close the Upper unit slowly. Be sure that the Upper unit is completely closed by pushing on edges with hands until you hear a click.
   

   
    Do not force the Upper unit to close. Doing so may damage the scanner.
