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 paper cassette(s), and 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 window. 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 carefully. To remove such parts, press the hook end of the latch
away from the part to which it is latched.
