Replacing the Consumable Product
Do not touch the toner. Keep the toner away from your eyes.
If toner gets on your skin or clothes, wash it off with soap and
water immediately.
Keep the imaging cartridge out of the reach of children.
Do not dispose of a used imaging cartridge in fire, as it may
explode and cause injury. Dispose of it 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.
