Toner Safety
About Toner
Toner is a nontoxic matter composed of plastic, iron and a trace of pigments.
Never throw toner in flames to avoid explosion.
Handling Adhered Toner
• Use dry tissue paper to wipe off toner adhered to skin or clothes and wash in water.
• Never use warm water for cleaning up toner to prevent toner particles from being able to
soak into fibers permanently.
• Toner particles are reactive with vinyl polymers. Avoid contacting these materials.

Replacing with wrong battery types may cause explosion.
Follow instructions to dispose used batteries properly.
