   Caution

   • We recommend that you place the toner cartridges on a clean, flat surface with a piece of disposable paper underneath it in case you accidentally spill or scatter toner.
   • DO NOT put a toner cartridge into a fire. It could explode, resulting in injuries.
   • Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
   • To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.
   

   Note

   • Be sure to seal up the toner cartridge tightly in a suitable bag so that toner powder does not spill out of the cartridge.
   • Discard the used toner cartridge according to local regulations, keeping it separate from domestic waste. If you have questions, call your local waste disposal office.
