Extended data:
All laser printers and copiers produce light ozone when they work. Ozone is an oxidant. Low-concentration ozone can be solved by disinfection and ventilation, but if inhaled too much, it will cause respiratory tract injury, decreased resistance, and easy to catch a cold, asthma and other diseases.
Genuine laser printers have undergone strict safety testing, and the ozone concentration produced is low, which will not cause harm to human body. However, many unqualified printers and copiers will release too much ozone concentration, which will have a certain impact on the body.
Offices that frequently use printers should pay attention to ventilation and disinfect the air regularly. When using the printer, you should stay away from the machine as far as possible, and then approach it after the smell dissipates after printing.
