Specifications 2-4 Service Manual Disassembly and Reassembly 3 3. Disassembly and Reassembly 3.1 General Precautions on Disassembly 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. 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.
