Safety Notices 
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 t he copier 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 copier drives some of its component s when it completes the warm-up period. Be 
careful to keep hands away from the me chanical and electrical components as the 
copier starts operation. 
5.  The inside and the metal parts of the fusi ng unit become extremely hot while the copier 
is operating. Be careful to avoid touc hing 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 discomf ort. Immediately wash eyes with plenty 
of water. If unsuccessful, get medical attention. 
2.  The copier, which use high voltage  power source, can generate ozone gas. High 
ozone density is harmful to human health. Ther efore, the machine must be installed in 
a well-ventilated room. 
Observance of Electrical Safety Standards 
The copier and its peripherals must be serv iced by a customer service representative who 
has completed the training  course on those models. 
 
ƒ 
  Keep the machine away from flammable liquids, gases, and aerosols. A fire or 
an explosion might occur. 
 
ƒ  The Controller board on this machine c ontains 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 manufactu rers instructions and local regulations. 
ƒ  The optional fax and memory expansion uni ts contain lithium batteries, which can  
						

							explode if replaced incorrectly. Replace only with the same or an equivalent type 
recommended by the 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 us ed toner. Toner dust may ignite suddenly when 
exposed to an open flame. 
2.  Dispose of used toner, t he maintenance unit which includes developer or the organic 
photoconductor in accordance with local r egulations. (These are non-toxic supplies.) 
3.  Dispose of replaced parts in  accordance with local regulations. 
4.  When keeping used lithium batte ries in order to dispose of them later, do not put more 
than 100 batteries per sealed box. Storing larg er 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. T he optical housing unit can only be repaired in a factory or at a 
location with the requisite equipment. The laser subsystem is replaceabl e 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 c hassis and laser subsystems to the factory or 
service depot when replacement of th e optical subsystem is required. 
 
ƒ  Use of controls, or adjustment, or  performance of procedures other than 
those specified in this manual may r esult in hazardous radiation exposure.  
 
ƒ  WA R N I N G : 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. 
ƒ  CAUTION MARKING:
