NOTE
All components in the HP Color LaserJet 3500/3550 and 3700 series printers use Phillips-
head screws that require a #2 Phillips screwdriver. Ensure that you have a Phillips
screwdriver and not a Posidriv screwdriver. Figure 6-1 (below) shows the difference between
a Phillips and a Posidriv screwdriver. Note that the Phillips tip has more beveled surfaces.
Figure 6-1.

Types of screws
Table 6-1, below, describes the screws used in the printer and provides guidelines to help
determine where to use each type of screw. 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.
