4-1 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 or replaced, any cables
disturbed by the procedure must be replaced 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. Move the printer cartridge to far right to cap the nozzle.
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.
