the network cable, and the telephone line from the machine,
except when performing the communication test, etc.
It may cause an injury or an electric shock.

2) There is a high temperature area inside the machine. Use an

extreme care when servicing.
It may cause a burn.

3) There is a high voltage section inside the machine which may

cause an electric shock. Be careful when servicing.

4) Do not disassemble the laser unit. Do not insert a reflective

material such as a screwdriver in the laser beam path.
It may damage eyes by reflection of laser beams.

5) When servicing with the machine operating, be careful not to

squeeze you hands by the chain, the belt, the gear, and other
driving sections.

6) Do not leave the machine with the cabinet disassembled.

Do not allow any person other than a serviceman to touch

causing breakdown or malfunction of the machine.

11) When carrying a unit with PWB or electronic parts installed to

it, be sure to put it in an anti-static-electricity bag.
It may cause a breakdown or malfunctions.

1) Be sure to connect the power cord only to a power outlet that

meets the specified voltage and current requirements.
Avoid complex wiring, which may lead to a fire or an electric
shock.
It may cause a fire or an electric shock.

2) If there is any abnormality such as a smoke or an abnormal

smell, interrupt the job and disconnect the power plug.
It may cause a fire or an electric shock.

3) Be sure to connect the grounding wire. If an electric leakage

occurs without grounding, a fire or an electric shock may
result.
To protect the machine and the power unit from lightening,
grounding must be made.

4) When connecting the grounding wire, never connect it to the

following points.
It may cause an explosion, a fire or an electric shock.

• Gas tube
• Lightning conductor
• A water pipe or a water faucet, which is not recognized as a

grounding object by the authorities.

• Grounding wire for telephone line

5)

Do not damage, break, or work the power cord.
Do not put heavy objects on the power cable. Do not bend it
forcibly or do not pull it extremely.
It may cause a fire or an electric shock.

6)

Keep the power cable away from a heat source.
Do not insert the power plug with dust on it into a power outlet.
It may cause a fire or an electric shock.

7)

Do not put a receptacle with water in it or a metal piece which

8)

With wet or oily hands, do not touch the power plug, do not
insert the telephone line jack, do not operate the machine, or
do not perform servicing.
It may cause an electric shock.

Do not install the machine at the following sites.
1)

Place of high temperature, high humidity, low tempera-
ture, low humidity, place under an extreme change in tem-
perature and humidity.
Paper may get damp and form dews inside the machine, caus-
ing paper jam or copy dirt.
For operating and storing conditions, refer to the specifications
described later.

2)

Place of much vibrations
It may cause a breakdown.

3)

Poorly ventilated place
An electro-static type copier will produce ozone inside it.
The quantity of ozone produced is designed to a low level so
as not to affect human bodies. However, continuous use of
such a machine may produce a smell of ozone. Install the
machine in a well ventilated place, and ventilate occasionally.

WARNING: If this WARNING should be ignored, a serious
