Operator Safety:
This machine is considered a class 1 laser device, safe for office/ EDP use. The machine contains a 5-
milliwat, 760 - 800 nanometer wavelength, GaAIAs laser diode. Direct (or indirect reflected) eye contact
with the laser beam might cause serious eye damage. Safety precautions and interlock mechanisms
have been designed to prevent any possible laser beam exposure to the operator.
The following label is attached on the back side of the machine.
Laser Safety:
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 thefield. Customerengineers aretherefore directedto return all chassisand laser sub-
systems to the factory or service depot when replacement of the optical subsystem is required.
Warning:
Use of controls or adjustment or performance of procedures other than those specified in this manual
might result in hazardous radiation exposure.
Notes:
Two kinds of size notation are employed in this manual. With this machine refer to the metric version.
For good copy quality, Ricoh recommends that you use genuine Ricoh toner.
Ricoh shall not be responsible for any damage or expense that might result from the use of parts other
than genuine Ricoh parts in your Ricoh office product.
Power Source:
220 – 240V, 50/60Hz, 6A or more

In this manual, the following important symbols are used:
Examples Of Indications
R
WARNING:
Ignoring this warning could cause serious injury or even death.
R
CAUTION:
Ignoring this caution could cause injury or damage to property.
Symbols Rmean a situation that requires you take care.
Symbols vmean “Hot surface”.
Do NOT carry out the operation represented by this symbol m.
This example means “Do not take apart”.
Symbols $mean you MUST perform this operation.
This example means “You must remove the wall plug”.

ii
R WARNING:
•
Only connect the machine to the power source described on
the inside front cover of this manual.
•
Avoid multi-wiring.
•
Do not damage, break or make any modifications tothe pow-
er cord. Do not place heavy objects on it, pull it hard or bend
it more than necessary. These actions could cause an elec-
tric shock or fire.
•
Do not plug or unplug the power cord with your hands wet.
Otherwise, an electric shock might occur.
•
Make sure the wall outlet is near the machine and freely ac-
cessible so that in event of an emergency it can be un-
plugged easily.
•
Do not remove any covers or screws other than those spec-
ified in this manual. Some parts of the machine are at a high
voltage and could give you an electric shock. Also, if the ma-
chine has laser systems, direct (or indirect) reflected eye
contact with the laser beam may cause serious eye damage.
When the machine needs to be checked, adjusted, or re-
paired, contact your service representative.
•
Do not take apart or attempt any modifications to this ma-
chine. There is a risk of fire, electric shock, explosion or loss
of sight. If the machine has laser systems, there is a risk of
serious eye damage.
•
If the machine looks damaged or breaks down, smoke is
coming out, there is a strange smell or anything looks unu-
sual, immediately turn off the operation and main power
switches then unplug the power cord from the wall. Do not
continue using the machine in this condition. Contact your
service representative.
•
If metal, liquid or foreign matter falls into the machine, turn
off the operation and main power switches, and unplug the
main power cord. Contact your service representative. Do
not keep using the machine with a fault or defect.
•
Do not put any metal objects or containers holding water
(e.g. vases, flowerpots, glasses) on the machine. If the con-
tents fall inside the machine, a fire or electric shock could
occur.

iii
• Do not incinerate used toner or toner containers. Toner dust
might ignite when exposed to an open flame. Dispose of the
used toner containers according to local regulations for
plastics.

iv
R CAUTION:
•
Keep the machine away from humidity and dust. A fire or an elec-
tric shock might occur.
• Do not place the machine on an unstable or tilted surface. If it top-
ples over, it could cause injury.
• After you move the machine, fix it with the caster fixture. Other-
wise,the machinemightmoveor come down to cause apersonal
injury.
• Before moving the machine, be sure to pull all four handles fully
out. Not doing this may result in an injury, such as getting your
fingers pinched. After moving the machine, return the four han-
dles to their original positions.
• When the optional paper tray unit is installed, do not push the up-
per part of the main unit horizontally. If the paper tray unit be-
comes detached from the main unit, this could cause an injury.
• When you move the machine, unplug the power cord from the
wall outlet to avoid fire or electric shock.
• When the machine will not be used for a long time, unplug the
power cord.
• When you pull out the plug from the socket, grip the plug to avoid
damaging the cord and causing fire or electric shock.
• If you use the machine in a confined space, make sure there is a
continuous air turnover.
• Do not reuse stapled paper. Do not use aluminum foil, carbon-
containing paper or other conductive paper. Otherwise, a fire
might occur.
• When removing misfed paper, do not touch the fusing section be-
cause it could be very hot.
• This machine has been tested for safety using this supplier's
parts and consumables. We recommend you only use these
specified supplies.

v
• Do not eat or swallow toner.
• Keep toner (used or unused) and toner containers out of reach of
children.
• This equipment is only to be installed by a qualified service per-
sonnel.
• Deliver to collection point for waste products. Do not be disposed
of via domestic refuse collection.
