IMPORTANT SAFETY NOTICES

PREVENTION OF PHYSICAL INJURY

1. Before disassembling or assembling parts of the copier and peripherals,

make sure that 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 peripherals are

supplied with electrical voltage even if the main 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.

5. The inside and the metal parts of the fusing unit become extremely hot

while the copier is operating. Be careful to avoid touching those
components with your bare hands.

HEALTH & SAFETY CONDITIONS

1. Never operate the copier without the ozone filters installed.

2. Always replace the ozone filters with the specified ones at the specified

intervals.

3. Toner and developer are non-toxic, but if you get either of them in your

eyes by accident, it may cause temporary eye discomfort. Try to remove
with eye drops or flush with water as first aid. If unsuccessful, get medical
attention.
