Copy machine

COPY MACHINE  – a device, which is used to copy the image and reproduce. The lens inside the copy machine focuses the original (document, book, etc.) image on the electrified metal cylinder.  In places where the image is dark, a static electrified field remains, which attracts the electrified powder from the special cartridges.

The received image is captured on the paper rotating cylinder. Modern copying machine uses additional devices: grouping, sorting, folding, stapling, leaflet production and paper supply drawers. Most commonly used size for copying a6 to a3.

History

In 1959 the first commercial copy machine appeared. The inventor Chester Carlsonas together with his friend German refugee Otto Kome created the first xerographic copier from zinc plate, low-cost chemicals and a simple lamp. The principle of its functioning was based on the fact, that by rubbing the cloth a static charge is created.

In 1971 the laser printer was created.

Health effects

When using the copier, the ozone gas may form. Ozone has a specific odor, which may be often felt when the copy device is under operation. If the concentration of the ozone in the premises, where to copier is used, increases up to some level, it may cause the irritation of nose, throat, eye mucous membranes, some headaches of  operator and other personnel who is in the room. Copiers emit some sort of noise and spread amount of electromagnetic radiation.

It is known that large concentration of ozone and aerosol may be harmful to the human health, have some negative impact on materials. Quite often happens that people use not new and modern copiers-printers, which can be potent sources of emission.  It is important that after some operation of the printer, the device would be disconnected for some short time and the premises aired, then ozone will split, in addition you will rest from the noise, and the electromagnetic radiation will not take place as well.
