Comparing Phillips and Posidriv screwdrivers Table 34 on page 137 describes the screws used in the printer and provides guidelines to help determine where each type of screw is used. The screws can vary in length depending on the thickness of the material being fastened. Always note where each type of screw is located and replace each one into its original location.
