Copiers and printers emit more radiation than computers, and they smell like toner when they work. Those are poisonous, so open the window when using them.
Copying machine is based on the photoconductive principle of selenium drum, which is generally safe and will not endanger human health. However, due to static electricity, some ozone molecules will be produced in the indoor air during the operation of the copier.
When the copier cools the ink on the newly printed paper, it will feel a "wind" at the paper outlet, and there is ozone in this "wind". Excessive inhalation is harmful to health. Therefore, when using the copier, we should try to avoid "wind".

1. Copying machines sold in the market usually have a rated voltage of 200V to 240V, a rated frequency of 50Hz, and a working current of about 8 A. If the copying machine is connected to a power socket with too high or too low voltage, it may affect the normal operation of the copying machine or even damage the copying machine.
In addition, it is best not to connect other equipment to the power socket connected to the copier, so as to avoid the current impact on the copier and damage the working circuit inside the copier when plugging and unplugging other equipment. In addition, the socket connected to the copier must be three-phase, and the power cord must not be folded or crushed; When turning off the copier, you must first turn off the power on the control panel of the copier, and then unplug the power cord later.
2. Usually, the toner used in photocopiers is mainly composed of carbon, and many of them are composed of adhesives and resins. At the moment when copying is about to be completed, the toner will melt into paper fibers at a high temperature of about 200 degrees Celsius, and the resin component will be oxidized into an irritating gas, which is actually what we often call ozone.
