Important Safety Notices
Prevention of Physical Injury
1. Before disassembling or assembling parts of the machine and peripherals, make sure that the
machine power cord is unplugged.
2. The wall outlet should be near the machine and easily accessible.
3. 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.
4. The machine drives some of its components when it completes the warm-up period. Be careful to
keep hands away from the mechanical and electrical components as the machine starts operation.
5. 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.
Health Safety Conditions
1. Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may
cause temporary eye discomfort. Immediately wash eyes with plenty of water. If unsuccessful, get
medical attention.
2. The machine, which use high voltage power source, can generate ozone gas. High ozone density
is harmful to human health. Therefore, the machine must be installed in a well-ventilated room.
Observance of Electrical Safety Standards
The machine and its peripherals must be serviced by a customer service representative who has
completed the training course on those models.
• Keep the machine away from flammable liquids, gases, and aerosols. A fire or an explosion
might occur.
• The Controller board on this machine contains a lithium battery. 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 batteries in accordance with the manufacturer's
instructions and local regulations.
• The optional fax and memory expansion units contain lithium batteries, which can explode if
replaced incorrectly. Replace only with the same or an equivalent type recommended by the
1
manufacturer. Do not recharge or burn the batteries. Used batteries must be handled in
accordance with local regulations.
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, the maintenance unit which includes developer or the organic
photoconductor 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.
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: Turn off the main switch before attempting any of the procedures in the Laser Optics
Housing Unit section. Laser beams can seriously damage your eyes.
• CAUTION MARKING:
2
The Aim of Anti-tip Components and Precautions
The anti-tip components are necessary for meeting the requirements of IEC60950-1, the international
standard for safety.
The aim of these components is to prevent the products, which are heavy in weight, from toppling as a
result of people running into or leaning onto the products, which can lead to serious accidents such as
persons becoming trapped under the product. (U.S.: UL60950-1, Europe: EN60950-1)
Therefore, removal of such components must always be with the consent of the customer. Do not remove
them at your own judgment.
Warnings, Cautions, Notes
In this manual, the following important symbols and notations are used.
• A Warning indicates a potentially hazardous situation. Failure to obey a Warning could result in
death or serious injury.
• A Caution indicates a potentially hazardous situation. Failure to obey a Caution could result in
minor or moderate injury or damage to the machine or other property.
• Obey these guidelines to avoid problems such as misfeeds, damage to originals, loss of valuable
data and to prevent damage to the machine.
• This information provides tips and advice about how to best service the machine.
