!
CAUTION
Turn off the main power switch and unplug the machine before starting any
of the replacement procedures described in this section.
Note that you should not turn off the main switch while mechanical parts are active,
as this may cause parts to stop out of home position. Attempting to remove or
install the PCU or other such units while parts are out of home position may result
in damage. Wait for operation to stop before turning off the machine.

3.1.2 LITHIUM BATTERIES

!

explosion. Replace only with the same type or with an equivalent type
recommended by the manufacturer. Discard used batteries in accordance
with the manufacturer's instructions.

The PCU consists of the OPC (Organic Photo Conductor) drum, charge roller,
development unit, and cleaning components. Observe the following precautions
when handling the PCU.

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.
