• EU Directive 2002/96/EC and EN50419
(European Union only)
This equipment is marked with the recycling symbol below. It means that at the end of the life of the
equipment you must dispose of it separately at an appropriate collection point and not place it in the

complies
device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the end user is encouraged
to try to correct the interference by one or more of the following measures:

with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
• A shielded interface cable should be used to ensure compliance with the limits for a Class B
digital device. Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
• Industry Canada Compliance Statement (For Canada)
This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe B est conforme à la norme NMB-003 du Canada.
Laser Safety (110 to 120 volt model only)
•
This machine is certified as a Class 1 laser product under the U.S. Department of Health and Human
Services (DHHS) Radiation Performance Standard according to the Radiation Control for Health and
Safety Act of 1968. This means that the machine does not produce hazardous laser radiation.
Since radiation emitted inside the machine is completely confined within protective housings and
external covers, the laser beam cannot escape from the machine during any phase of user operation.
• FDA Regulations (110 to 120 volt model only)
The U.S. Food and Drug Administration (FDA) has implemented regulations for laser products
manufactured on and after August 2, 1976. Compliance is mandatory for products marketed in the
United States. The following label on the back of the machine indicates compliance with the FDA
regulations and must be attached to laser products marketed in the United States.
MANUFACTURED:
RICOH COMPANY LTD, 3-6, Naka-magome 1-Chome Ohta-ku, Tokyo 143-8555, Japan
Complies with FDA performance standards for laser products except for deviations pursuant to
Laser Notice No. 50, dated June 24, 2007.
• Internal laser radiation
Maximum radiation power: 10 mW
Wave length: 780 - 800 nm

Safety Information
• Caution for Laser Product (WARNHINWEIS fur Laser drucker)
CAUTION:
When
the machine during servicing is operated with the cover open, the regulations of VBG 93 and
the performance instructions for VBG 93 are valid.
CAUTION:
In case of any trouble with the laser unit, replace the laser unit itself. To prevent direct exposure to the
laser beam, do not try to open the enclosure of the laser unit.
ACHTUNG:
Im Falle von Störungen der Lasereinheit muß diese ersetzt werden. Das Gehäuse der Lasereinheit darf
nicht geöffnet werden, da sonst Laserstrahlen austreten können.
• Additional Information
When servicing the optical system of the machine, be careful not to place a screwdriver or other
reflective object in the path of the laser beam. Be sure to take off any personal accessories such as
watches and rings before working on the machine. A reflected beam, though invisible, can
permanently damage the eyes.
Since the beam is invisible, the following caution label is attached on the laser unit.
• Definitions of Warnings, Cautions, and Notes
The following conventions are used in this manual:
Warnings tell you what to do to prevent possible personal injury.
Cautions specify procedures you must follow or avoid to prevent possible damage to the machine or
other objects.

Operating Environment
1. Put your machine on a flat, stable surface such as a desk that is free of vibration and shocks.
2. Use the

4. Condensation
machine in a well-ventilated room; use the machine within the following ranges of temperature
and humidity: temperature between 10 °C and 32.5 °C (50 °F to 90.5 °F), and the relative humidity
is maintained between 20% and 80%.
When the machine is moved from a cold place into a warm room, condensation may occur inside
the machine, causing various problems as listed below.
• Condensation on the optical surfaces such as the scanner window, lenses, the reflection mirror
and the protection glass may cause the print image to be light.
• If the exposure drum is cold, the electrical resistance of the photosensitive layer is increased,
making it impossible to obtain the correct contrast when printing.
• Condensation on the charge unit may cause corona charge leakage.
• Condensation on the plate and separation pad may cause paper feed failures.
If condensation has occurred, leave the machine for at least 2 hours to allow it to reach room
temperature.
If the drum unit is unpacked soon after it is moved from a cold place to a warm room, condensation
may occur inside the unit which may cause incorrect images. Instruct the end user to allow the unit to
come to room temperature before unpacking it. This will take one or two hours.
Power Supply
1. The AC input power supply described on the rating plate of the machine should be within ±10% of
the rated voltage.
2. The AC input power supply is within the regulated value.
3.
The cables and harnesses are connected correctly.
4. The fuses are not blown.

creating secondary problems by mishandling, follow the warnings and precautions below during
WARNING
• Always turn off the power switch and unplug the power cord from the power outlet before accessing
any parts inside the machine.
•
When opening the front cover or back cover to access any parts inside the machine, never touch
the shaded parts shown in the following figures.
• DO NOT use flammable substances such as alcohol, benzine, thinner or any type of spray to clean
the inside or outside of the machine. Doing this may cause a fire or electrical shock.
• Be careful not to lose screws, washers, or other parts removed.
• Be sure to apply grease to the gears and applicable positions specified in this chapter.
•
When using soldering irons or other heat-generating tools, take care not to accidentally damage
parts such as wires, PCBs and covers.
• Static electricity charged in your body may damage electronic parts. When transporting PCBs, be
sure to wrap them in conductive sheets.
• When replacing the PCB and all the other related parts, put on a grounding wrist band and perform
the job on a static mat. Also take care not to touch the conductor sections on the flat cables or on the
wire harness.
• When connecting or disconnecting cable connectors, hold the connector body, not the cables. If the
connector has a lock, release the connector lock first to release it.
• After a repair, check not only the repaired portion but also all connectors. Also check that other related
portions are functioning properly before operational checks.
• After disconnecting flat cables, check that each cable is not damaged at its end or short-circuited.

• When connecting flat cables, do not insert them at an angle. After insertion, check that the cables are
not at an angle.
