Kopiokoneen

Kopiokoneen, also known as the copy machine or photocopier, is an electro-mechanical device used to produce multiple copies of a document. It works by using a combination of light and heat to produce a copy of the original document. The process begins with the original document being placed on a glass plate. The light from a lamp is then reflected off the document and onto a photoconductive drum. The drum is coated with a material that becomes conductive when exposed to light. The areas of the drum that are exposed to light become conductive, while the areas that are not exposed remain non-conductive. A toner, which is a fine powder, is then applied to the drum. The toner sticks to the conductive areas of the drum, creating an image of the original document. The toner is then transferred to a blank piece of paper, which is then heated and pressed to fuse the toner to the paper. The resulting copy is then ejected from the machine. Kopiokoneen are commonly used in offices, schools, and other settings where multiple copies of a document are needed. They are available in various sizes and with different features, such as the ability to make color copies or to scan and email documents.
