P-1 PL 02 · Do not modify this product, as a fire, electrical shock, or breakdown could result. If the product employs a laser, the laser beam source could cause blindness. · Do not attempt to remove the covers and panels which have been fixed to the product. Some products have a high-voltage part or a laser beam source inside that could cause an electrical shock or blindness.
· Only use the power cord supplied in the package. Failure to use this cord could result in a fire or electrical shock. · Use only the specified power source voltage. Failure to do that could result in a fire or electrical shock. · Do not use a multiple outlet adapter to connect any other appliances or machines. Use of a power outlet for more than the marked current value could result in a fire or electrical shock.
Do not unplug and plug in the power cord with a wet hand, as an electrical shock could result.
Plug the power cord all the way into the power outlet. Failure to do this could result in a fire or electrical shock.
· Do not scratch, abrade, place a heavy object on, heat, twist, bend, pull on, or dam- age the power cord. Use of a damaged power cord (exposed core wire, broken wire, etc.) could result in a fire or breakdown. Should any of these conditions be found, immediately turn OFF the power switch, unplug the power cord from the power outlet, and then call your authorized ser- vice representative. · In principle, do not use an extension cord. Use of an extension cord could cause a fire or electrical shock. Contact your authorized service representative if an extension cord is required.
P-2 Do not place a flower vase or other container that contains water, or metal clips or other small metallic objects on this product. Spilled water or metallic objects dropped inside the product could result in a fire, electrical shock, or breakdown.

1139O1620A vi Safety Information
This device must be used with shielded interface (Parallel) cable and shielded network (10/100Base-T) cable. The use of non-shielded cable is likely to result in interference with radio communications and is prohibited under 89/336/EEC rules.
The LAN port of this machine is for the indoor cable splicing. An outdoor cable cannot be used. vii Safety Information
Laser Safety This is a digital machine which operates by means of a laser. There is no possibility of danger from the laser, provided the machine is operated according to the instructions in this manual. Since radiation emitted by the laser is completely confined within protective housing, the laser beam cannot escape from the machine during any phase of user operation. This machine is certified as a Class 1 laser product. This means the machine does not produce hazardous laser radiation.
Internal Laser Radiation Maximum Average Radiat Power: 78.1 µW at the laser aperture of the upper print head unit. Wavelength: 675-695 nm This product employs a Class IIIb Laser Diode that emits a laser beam. The Laser Diode and the Scanning Polygon Mirror are Incorporated in the print head unit. The print head unit is NOT A FIELD SERVICE ITEM. Therefore, the print head unit should not be opened under any circumstances.

Ozone Release NOTE = Locate the Machine in a Well Ventilated Room = A negligible amount of ozone is generated during normal operation of this machine. An unpleasant odor may, however, be created in poorly ventilated rooms during extensive machine operations. For a comfortable, healthy, and safe operating environment, it is recommended that the room well ventilated.
REMARQUE = Placer l'appareil dans une pièce largement ventilée = Une quantité d'ozone négligable est dégagée pendant le fonctionnement de l'appareil quand celui-ci est utilisé normalement. Cependant, une odeur désagréable peut être ressentie dans les pièces dont l'aération est insuffisante et lorsque une utilisation prolongée de l'appareil est effectuée. Pour avoir la certitude de travailler dans un environnement réunissant des conditions de confort, santé et de sécurité, il est préférable de bien aérer la pièce ou se trouve l'appareil.

Moving If you need to transport the copier over a long distance, consult your Technical Representative.
Care of Copier Supplies Use the following precautions when handling the copier supplies (toner, paper, etc.).
N Store the paper, toner, and other supplies in a place free from direct sunlight and away from any heating apparatus. Keep them in a dry, clean environment. N Store paper, which has been removed from its wrapper but not loaded into the Drawer, in a sealed plastic bag in a cool, dark place. N Keep supplies out of the reach of children. N If your hands become soiled with toner, wash them with soap and water immediately. 1-3 2. Precautions for Use Chapter 1
Storage of Copies · If copies are to be kept for a long time, keep them in a place which is not exposed to light to prevent fad- ing. · If an adhesive containing solvent (e.g., spray glue) is used to paste copies, the toner on the copies can melt. Safety Notes
· The color copies have a toner layer thicker than the normal black-and-white copies. When a color copy is folded, therefore, the toner at the fold can be separated. NOTE This copier is equipped with a counterfeit preventive function that can cause slight noise on the copy image.
Useful Tip By activating the "Copy Track Functions" offered by this copier, nobody can use the copier unless he or she enters an access number that's unique to his/her account. It helps prevent dishonest use of the copier.
Legal Restrictions on Copying Certain types of documents must never be copied by the copier for the purpose or with the intent to pass copies of such documents off as the original. The following is not a complete list but is meant to be used as a guide to responsible copying.
Financial Instruments ·Personal Checks ·Travelers Checks ·Money Orders ·Certificates of Deposit ·Bonds or other Certificates of Indebtedness ·Stock Certificates
Legal Documents ·Food Stamps ·Postage Stamps (canceled or uncanceled) ·Checks or Drafts drawn by Government Agencies ·Internal Revenue Stamps (canceled or uncanceled) ·Passports ·Immigration Papers ·Motor Vehicle Licenses and Titles ·House and Property Titles and Deeds
