Safety precautions

Be sure to follow the precautions carefully to ensure safe, efficient operation:

  • Because the product weighs approximately 33.1 kg (73 lb) for EPSON AcuLaser CX11NF/CX11F, and 30.9 kg (68.1 lb) for EPSON AcuLaser CX11N/CX11, excluding consumable products, one person should not lift or carry it. Two people should carry the product, lifting it by the correct positions as shown below.

Be very careful when lifting the product as the rear side is heavier than the front.

  • Be careful not to touch the fuser, which is marked CAUTION HIGH TEMPERATURE, or the surrounding areas. If the product has been in use, the fuser and the surrounding areas may be very hot.

  • Do not insert your hand deep into the fuser unit as some components are sharp and may cause injury.

  • Avoid touching the components inside the product unless instructed to do so in this guide.

  • Never force the product's components into place. Although the product is designed to be sturdy, rough handling can damage it.

  • When handling a toner cartridge, always place them on a clean, smooth surface.

  • Do not attempt to modify a toner cartridge or take them apart. They cannot be refilled.

  • Do not touch the toner. Keep the toner away from your eyes.

  • Do not dispose of used toner cartridge, photoconductor units, or fuser units in fire, as they can explode and cause injury. Dispose of them according to local regulations.

  • If toner is spilled, use a broom and dustpan or a damp cloth with soap and water to clean it up. Because the fine particles can cause a fire or explosion if they come into contact with a spark, do not use a vacuum cleaner.

  • Wait at least one hour before using a toner cartridge after moving it from a cool to a warm environment to prevent damage from condensation.

  • When removing the photoconductor unit, avoid exposing it to room light for more than five minutes. The unit contains a blue-colored light-sensitive drum. Exposure to light can damage the drum, causing dark or light areas to appear on the printed page and reducing the service life of the drum. If you need to keep the unit out of the product for long periods, cover it with an opaque cloth.

  • Be careful not to scratch the surface of the drum and belt. When you remove the photoconductor unit from the product, always place the unit on a clean, smooth surface. Avoid touching the drum, since oil from your skin can permanently damage its surface and affect print quality.

  • To get the best print quality, do not store the photoconductor unit in an area subject to direct sunlight, dust, salty air, or corrosive gases (such as ammonia). Avoid locations subject to extreme or rapid changes in temperature or humidity.

  • Be sure to keep consumable components out of the reach of children.

  • Do not leave jammed paper inside the product. This can cause the product to overheat.

  • Avoid sharing outlets with other appliances.

  • Use only an outlet that meets the power requirements of this product.
