Screws Used in the Printer
All screws used in the printer are Phillips head, which require a
Phillips screwdriver. The following figure shows the difference
between a Phillips and a Posidriv screwdriver. Note that the Phillips
tip has more beveled surfaces.
CAUTION Using a Posidriv screwdriver will damage the screw heads. Use Phillips
only.
Figure 6-1 Comparing Phillips and Posidriv Screwdrivers
Table 6-1 on page 6-4 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.
