1.5.3 Safety of Toner

The machine's toner is a non-toxic material composed of plastic, iron, and small amounts of dye.
Do not put the toner into fire. It may explode.
Toner on the Skin or Clothes
1. If your skin or clothes came into contact with toner, use dry tissue to remove the toner, and then wash with water.
2. Do not use warm or hot water, which will cause the toner to jell, permanently fusing it with the fibers of the clothes.
3. Do not bring toner into contact with vinyl material. They are likely to react with each other.
