3-1 General Precautions on Disassembly
When you disassemble and reassemble components, 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 removing
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.
