Ricoh 920F Operating Instructions Manual page 108

• If the power cord is damaged (exposure of the core, disconnection, etc.), contact your service
representative to change a new one. Operating the machine with a damaged power cord may
cause an electric shock or fire.
• Be sure to push the plug of the power cord fully into the wall outlet. Partially inserted plugs create
an unstable connection that can result in unsafe buildup of heat.
• If this machine is not going to be used for several days or longer at a time, disconnect its power
cord from the wall outlet.
• When disconnecting the power cord from the wall outlet, always pull the plug, not the cord. Pulling
the cord can damage the power cord. Use of damaged power cords could result in fire or electric
shock.
• Be sure to disconnect the plug from the wall outlet and clean the prongs and the area around the
prongs at least once a year. Allowing dust to build up on the plug constitutes a fire hazard.
• When performing maintenance on the machine, always disconnect the power cord from the wall
outlet.
• Make sure the plug is inserted firmly in the wall outlet.
• Voltage must not fluctuate by more than 10%.
• The wall outlet shall be installed near the machine and shall be easily accessible.
