Precautions to take when you get toner onto your hands or into clothing:

• If toner gets on your hands or clothing, wash them immediately with cold water.
• The toner sets onto hands or into clothing if you try to wash it with warm water. Once it is set, you can hardly remove the toner stains.

IMPORTANT
