Laser radiation can prove to be harmful to the human body. The host machine's laser scanning system is completely sealed by means of a protective housing and
external covers so that its light will not leak outside the host machine as long as the host machine is used normally.

These regulations apply to laser products produced on and after August 1st, 1976, and prohibit the sale of laser products without certification.

1.1.2.4 Safety of the Toner
0016-1806
Toner in General
Toner is a non-toxic material made up of plastic, iron, and small amounts of dye.
Do not throw toner into fire. Doing so can lead to explosion.
Contact with Toner
1. Toner on the skin or clothes must be removed by washing with water immediately.
2. The use of warm water must be avoided, doing so will cause the toner to turn gel-like and to permanently fuse with the fibers of the clothes.
3. Contact with vinyl must also be avoided, as toner can readily react.
1.1.2.5 Fire Attention
0016-1807
It is dangerous to throw the parts that include combustible materials such as lithium battery and toner cartridge etc., into fire. Any used battery must always be
disposed according to the appropriate local regulations.
