GP 8 General Disassembly Precautions

Purpose
Use these precautions when disassembling and reassembling components.
Procedure
NOTE: The close proximity of cables to moving parts makes proper routing essential. If com-
ponents are removed, any cables disturbed by the procedure must be restored as close as
possible to their original positions. Before removing any component from the machine, note the
cable routing that will be affected.
Whenever servicing the machine, perform the following:
1. Check to verify that jobs are not stored in memory.
2. Unplug the power cord.
3. Use a flat and clean surface.
4. Only install authorized components.
5. Do not forcibly remove plastic components.
6. Ensure all components are in their correct position.
7. When replacing screws into plastic components, turn the screw counterclockwise to
engage the original thread, then turn the screw clockwise. Do not overtighten. If a new
thread is cut, the plastic component will lose the ability to hold the screw. This also applies
to metal components.
