3. Disassembly and Reassembly
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. Remove the print cartridge. Do not expose the cartridge to direct room light or sun light, and be careful not
to scratch the drum surface.
2. Turn the power switch off.
3. Unplug all the cables from the printer.
4. Replace with only an authorized component.
5. Do not force to open or fasten a plastic material component.
6. Be careful no obstacles are included when you reassemble components.
7. When you reassemble components, be careful small size components are located in place.
8. If you turn the machine over to replace some parts, toner or paper particles may contaminate the LSU win-
dow. Protect the LSU window with clean paper.
Releasing Plastic Latches
Many of the parts are held in place with plastic
latches. The latches break easily; release them care-
fully. To remove such parts, press the hook end of
the latch away from the part to which it is latched.
