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 parts.
3. Unplug the power cord.
4. Use a flat and clean surface.
5. Replace only with authorized components.
6. Do not force plastic-material components.
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.
