the copier power cord is unplugged.
2. The wall outlet should be near the copier and easily accessible.
3. Note that some components of the copier and the paper tray unit are supplied with
electrical voltage even if the main power switch is turned off.
4. If any adjustment or operation check has to be made with exterior covers off or open
while the main switch is turned on, keep hands away from electrified or mechanically
driven components.

To prevent a fire or explosion, keep the machine away from flammable liquids,
gases, and aerosols.
