3. REPLACEMENT AND ADJUSTMENT
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.
3.1.1 CHECK POINTS FOR SERVICING
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 print 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.
3.1.2 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.
