When cleaning or replacing the pickup roller, feed rollers, or retard roller, use the appropriate procedure to remove and replace the rollers.

• Turn ON the power to the scanner to remove or attach the pickup roller. Be careful when working on the scanner when the power is ON.
• Do not use excessive force when removing or attaching the rollers. Doing so may damage them.

1. Turn ON the power.
   
   
   Because the pickup roller locks when the power is OFF, it will not fall forward when the upper unit is opened.

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 causing a feeding error.
   
   
3. Push up on the pickup roller to open the hook, and then remove the pickup roller.
   
   
   
4. Wipe the pickup roller with a firmly wrung cloth moistened with water.
   
   
   
   Do not use detergent to clean the rollers, since any detergent on the rollers could cause a feeding error.
   
   
5. Hold the pickup roller by sides of its shaft, and place it on the hooks.
   
   
   
   Take note of the orientation of the pickup roller. Putting it in backward and forcing it may damage the scanner.
   
   
6. Place the shaft of the pickup roller on the hooks, and then press it into place.
   
   
   
7. Make sure that the shaft of the pickup roller is correctly inserted.
   
   
   
8. 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.
