Important Safety Notices

Safety

Prevention of Physical Injury

1. Before disassembling or assembling parts of the machine and peripherals, make sure that the

machine and peripheral power cords are unplugged.

2. The plug should be near the machine and easily accessible.

3. Note that some components of the machine 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.

5. If the [Start] key is pressed before the machine completes the warm-up period (the [Start] key starts

blinking red and green), keep hands away from the mechanical and the electrical components as

the machine starts making copies as soon as the warm-up period is completed.

6. The inside and the metal parts of the fusing unit become extremely hot while the machine is

operating. Be careful to avoid touching those components with your bare hands.

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

aerosols.

Health Safety Conditions

1. For the model with ozone filters installed at the factory, never operate the machine without the

ozone filters installed.

2. For the model with ozone filters installed at the factory, always replace the filters with the specified

types at the proper 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.

Observance of Electrical Safety Standards

1. The machine and its peripherals must be installed and maintained by a customer service

representative who has completed the training course on those models.

Safety and Ecological Notes for Disposal

1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an

open flame.

2. Dispose of used toner, developer, and organic photoconductors in accordance with local

regulations. (These are non-toxic supplies.)

3. Dispose of replaced parts in accordance with local regulations.

4. When keeping used lithium batteries in order to dispose of them later, do not put more than 100

batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical

reactions and heat build-up.

• The danger of explosion exists if a battery of this type is incorrectly replaced. Replace only with the

same or an equivalent type recommended by the manufacturer. Discard used batteries in

accordance with the manufacturer’s instructions.

Handling Toner

• Work carefully when removing paper jams or replacing toner bottles or cartridges to avoid spilling

toner on clothing or the hands.

• If toner is inhaled, immediately gargle with large amounts of cold water and move to a well

ventilated location. If there are signs of irritation or other problems, seek medical attention.

• If toner gets on the skin, wash immediately with soap and cold running water.

• If toner gets into the eyes, flush the eyes with cold running water or eye wash. If there are signs of

irritation or other problems, seek medical attention.

• If toner is swallowed, drink a large amount of cold water to dilute the ingested toner. If there are

signs of any problem, seek medical attention.

• If toner spills on clothing, wash the affected area immediately with soap and cold water. Never use

hot water! Hot water can cause toner to set and permanently stain fabric.

• Always store toner and developer supplies such as toner and developer packages, cartridges, and

bottles (including used toner and empty bottles and cartridges) out of the reach of children.

• Always store fresh toner supplies or empty bottles or cartridges in a cool, dry location that is not

exposed to direct sunlight.

Laser Safety

The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units

in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite

equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser

chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and

laser subsystems to the factory or service depot when replacement of the optical subsystem is required.

• Use of controls, or adjustment, or performance of procedures other than those specified in this

manual may result in hazardous radiation exposure.

WARNING FOR LASER UNIT

WARNING:

Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser beams

can seriously damage your eyes.

CAUTION MARKING:

Safety Precautions for This Machine

Before moving the mainframe:

• Disconnect all peripheral units (finisher, LCT, etc.) from the mainframe.

• Hold the four holders of the mainframe to lift the mainframe. For details, see the “Copier

Installation” in the field service manual.
