Important Safety Notices

Prevention of Physical Injury

1. Before disassembling or assembling parts of the copier and peripherals, make sure that the 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 a job has started before the copier completes the warm-up or initializing period, keep hands away

from the mechanical and electrical components because the starts making copies as soon as the warm-

up period is completed.

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

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

The copier 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.

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

CÓPIA NÃO CONTROLADA

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

Laser beams can seriously damage your eyes.
