Fastener Types
The following table lists the primary types of Posi-Drive screws used to
assemble the printer. The procedures provide dimensional specifications for
screws being removed.
Use care when installing self-tapping screws in plastic. To properly start the
screw in plastic, turn the screw counter-clockwise in the hole until you feel the
screw engage the threads, then tighten as usual. Always use the correct type
and size screw and properly align the screw to prevent damaging the tapped
holes. Do not use excessive force to remove or install either a screw or a
printer part.
