Handling the consumable products and maintenance parts
❏ Do not burn used consumable products or maintenance parts because they might explode and
injure someone. Dispose of them according to local regulations.
❏ Be sure to keep consumable products and maintenance parts out of the reach of children.
❏ When handling a toner cartridge, always place it on a clean, smooth surface.
❏ Do not attempt to modify or take it apart consumable products or maintenance parts.
❏ Do not touch the toner. Always keep toner away from your eyes. If toner gets on your skin or
clothes, wash it off with soap and water immediately.
❏ 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.
