3. REPLACEMENT AND ADJUSTMENT
3.1 BEFORE YOU START
3.1.1 GENERAL PRECAUTIONS

If there are printer jobs in the machine, print out all jobs in the printer buffer.

Turn off the main power switch and unplug the machine before you do the procedures in
this section.
Use extreme caution when removing and replacing components. The cables in the machine are
located very close to moving parts; proper routing is a must.
After components have been removed, any cables that have been displaced during the procedure
must be restored as close as possible to their original positions. Before removing any component
from the machine, note any cable routings that may be affected.
Before servicing the machine:
1. Verify that documents are not stored in memory.
2. Remove the print cartridge before you remove parts.
3. Unplug the power cord.
4. Work on a flat and clean surface.
5. Replace with authorized components only.
6. Do not force plastic material components.
Make sure all components are returned to their original positions.
AIO
The AIO consists of the OPC drum, charge roller, development unit, cleaning components and
toner tank. Observe the following precautions when handling the AIO.
1. Never touch the drum surface with bare hands. If the drum surface is dirty or if you have
accidentally touched it, wipe it with a dry cloth, or clean it with wet cotton and then wipe it dry
with a cloth.
2. Never use alcohol to clean the drum. Alcohol will dissolve the drum surface.
3. Store the AIO in a cool dry place.
4. Do not expose the drum to corrosive gases (ammonia, etc.).
5. Do not shake a used AIO, as this may cause toner to spill out.
6. Dispose of used AIO components in accordance with local regulations.
