5. Disassembly and Reassembly
5.1 General Precautions on Disassembly
When you disassemble and reassemble compo-
nents, you must use extreme caution. The close
proximity of cables to moving parts makes proper
routing a must.
If components are removed, any cables disturbed
by the procedure must be restored as close as
possible to their original positions. Before remov-
ing any component from the machine, note the
cable routing that will be affected.
Whenever servicing the machine, you
must perform as follows:
1. Check to verify that documents are not stored
in memory.
2. Be sure to remove the toner cartridge before
you disassemble any parts.
3. Unplug the power cord.
4. Use a flat and clean surface.
5. Replace only with authorized components.
6. Do not excessive force on components made of
plastic, they may break.
7. Make sure all components are in their proper
position.
Releasing Plastic Latches
Many of the parts are held in place with plastic
latches. The latches break easily; release them
carefully.
To remove such parts, press the hook end of the
latch away from the part to which it is latched.
