Table 6-2 describes the screws used in the printers, 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.

Typically, plated screws are used in areas visible to the customer, and black screws are used in all other areas of the printer. Always note where each type of screw is located and replace each one into its original location.
