HP digital sender 9200c Manuale Di Servizio

This table describes the screws used in the digital sender 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 that is being fastened. Always note where each type of screw is located and replace each
one in its original location.

When you are disassembling the product, place the screws into the chassis holes

from which they were removed. This prevents their loss, and ensures that the proper type and
length of screw for each location is used when the product is reassembled

  Common fasteners used in this MFP

Phillips machine screw with captive star
washer

This screw is used to fasten metal to metal when good electrical contact is
needed. This screw also provides high resistance to loosening.

Phillips screw with self-tapping threads

This screw is used to fasten sheet metal or plastic to plastic frames (the deep,
coarsely spaced threads provide an increased holding capability while
decreasing the possibility of stripping the target hole).

To install a self-tapping screw, first turn it counterclockwise to

align it with the existing thread pattern, and then carefully turn it
clockwise to tighten it. You will feel resistance and hear the screw click
when it engages the existing threads in the hole. Do not overtighten the
screw. If a self-tapping screw-hole becomes stripped, repair the screw-
hole or replace the affected assembly.

Phillips washer-head machine screw
with a broad, flat washer attached to the
screw head

This screw is used to fasten sheet metal parts to the sheet metal chassis. It
spans large clearance holes and distributes the load by increasing the bearing
surface.
