6.2 REPLACEMENT OF COMPONENTS

6.2.1 GENERAL NOTES AND CAUTIONS

While removing and installing the components, it is necessary to use extreme caution. The close proximity of
cables to moving parts makes proper routing a must. If modules are removed or replaced, any cables disturbed by
the procedure must be restored as close as possible to their original positions. Before removing any module from
the machine, note the cable routing that will be affected.

Take the following precautions whenever servicing the machine.

1. Check to verify that no documents are stored in memory. If so, wait until memory is empty.

2. Turn off the power switch and unplug the power cord.

3. Unplug all line cord.

4. Remove the recording paper cassette, all trays, toner cartridge, drum cartridge, and fuser felt.

5. Place the drum and toner cartridges in a safe place away from light.

The following are removal instructions for the major components of the fax machine. Generally, replacement
procedures are the reverse of those for removing components. Where a replacement procedure differs from the
way the component is removed, or where a particular aspect of a replacement procedure needs clarification, a
reassembly note is provided.
