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 the 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 components when it completes the warm-up period. Be 
careful to keep hands away from the mechanical and electrical components as the 
copier starts operation. 
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 
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 copier, 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 copier and its peripherals must be serviced 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 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 manufacturers instructions and local regulations. 
ƒ  The optional fax and memory expansion units contain lithium batteries, which can  
						

							B230/B237 ii  SM 
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 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. 
 
ƒ Use of controls, or adjustment, or performance of procedures other than 
those specified in this manual may result 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:
