<ul><li><p>Step by step on changing Optical Prism Take out prism from mounting </p><p>1. Take out optical sensor from reader. 2. Take out the stopper and remove the FFC cable from both side connector. </p><p> (Fig 1) </p><p> 3. Unscrew 3 screw found beside the optical sensor </p><p> (Fig 2) 4. Slowly remove away the plastic cover found on one side </p><p> (Fig 3) </p><p>Stopper </p></li><li><p>5. By using a flat and fine item (such as screw driver), slowly take out the optical prism. </p><p> (Fig 4) </p><p>6. Slowly take out the whole prism from its mount without broken the mounting itself </p><p> (Fig 5) </p></li><li><p>Install the new prism into the mounting 1. Clean the new prism slowly and make sure not dust or dirt on two major surfaces. </p><p>Refer Fig 6. (Never use rough cloth or tissue to clean the prism. This might scratch the silicon coating surface) </p><p> (Fig 6) </p><p>2. Place the prism slowly back to the mounting as shown in Fig 5. 3. Once the prism has hold firmly in the mounting, close the plastic cover and place </p><p>3 screw back to its position.(Fig 3 and Fig 2) 4. Slowly put back the FFC cable and lock it properly.
