LED Radiation Safety

This product is a copier which operates by means of a LED (light emitting diodes) exposure system. There is no possibility of danger from the LED optical radiation, because the LED optical radiation level does not exceed the accessible radiation limit of class 1 under all conditions of operation, maintenance, service and failure.

Ozone Release

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 be well ventilated.

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 environnment réunissant des conditions de confort, santé et de sécurité, il est préférable de bien aérer la pièce ou se trouve l’appareil.

✚

Be careful not to spill toner inside the copier or get toner on your clothes or hands.

If your hands become soiled with toner, immediately wash them with soap and water.

If toner gets in your eyes, immediately flush them with water, and then seek professional medical advice.
